If anybody wants to see bigger tires done and has some laying around we are up for the challenge :D Next time probably with bottled nitrogen to save some time. I don't want to wait 8 hours on the bunker to tires to explode :D
to shorten the wait you could separate the filling in two stages using different compressors for each, first stage with a compressor that does high volume/low pressure, and only then moving to a low volume/high pressure compressor
This episode brings back bad memories of my first year as a mechanic. I was mounting large truck tires and nobody told me any of the safety rules, so after having mounted a few, using bars no machine, I was tired and was sitting on a tire while filling it. I didn't know that the rim was slightly warped, so it detonated at just over 100psi, sending me (250lbs) up about 4 feet and over 8 feet. The tire hit the shop wall about 30 feet away. I walked away from that with sand blasted eye balls and some bruising, I consider myself very fortunate.
I saw a truck tire explode in a cage.. even in a cage it completely bent up the cage bars.. though the cage did stay together and did stay anchroed to the floor... the blast was so strong just the blast wave broke the window from the office / waiting area of the shop.. it was a standard 11R22.5 tire.. a brand new one.. that particular tech was the only one who used the cages for single piece rims... after that occured the rules were everyone use a cage no matter what tire they were filling.. the consensus was that the exploding tire was defective... they were going up to 115 PSI with it.. the pressure was somewhere between 100 and 115.. the yhad just checled it and it showed 100 then they started ot inflater and boom.. sidewall failure
Very fortunate similar experience with me at a trucking company I had turned to get a drink of water and it sent the rim where I was standing 2 seconds earlier
@@Helo735 Had I been sitting absolutely anywhere else on the tire it would have hit me instead of throwing me. The warped part of the rim was directly under my butt, pointed at the floor.
I inflate 22.5" tires at work, I put it in a safety cage, use air regulated to 125 psi, and I walk away and work on things on the other side of the shop for about 15 minutes. This here is a great demonstration of why I do it this way.
In 1971 my father was working in a tire shop on a set of split rim truck tires when on of them blue apart. He had not secured the locking ring properly. It tore 3 fingers off of hie left hand and broke 7 ribs. Two had multiple fractures. He also had severe bruising on the entire front of his body and lost the earlobe on his left ear. Somehow his hearing recovered and his eyes were not damaged. He was told by the insurance people he was one of the lucky 1 in ten that actually survive that kind of accident. Most people are bending over the tire assembly when they blow. He had stood up and was turning to walk away when all hell cut loose. Thanks for demonstrating the incredible raw power released when these things go wrong.
I had to watch this! About 55 years ago I was mounting a 15 inch garden tractor tire on a rim so I could use it on a home made dune buggy. I was kneeling down on a concrete driveway and holding the air chuck on the valve stem. Really don't know how much pressure went in, but the bead cable/wire broke in the bottom bead of the tire. The rim and wheel went straight up in the air through an aluminum car port and probably about 20 feet higher. I was stunned and when I came to my senses I was watching the tire and wheel come back down and bounce off the hood of my '62 Chevy p/u. Then I realized I was standing where I had been kneeling and I was holding my right arm with my left hand. Both bones in my forearm were shattered and had to have surgery with pins implanted. This is entertaining to watch, but not to live through. Everyone should be really careful with tires and air pressure. I'm very thankful I was not decapitated or killed!
A man that went to my congregation had his arm blown off by this very same thing! I never talked to him because I was just a teenager, but that was what I had heard what happened to him... 😩
Thank you for sharing your experience. A day shift worker, about five years back died because of a tyre explosion. It is rather a comfort that he likely felt nothing. I saw the damage it did to the Few use the tyre cage. It has to be signed out to get it out of the equipment room, as all the heavy duty equipment had to be. Often, my signature is the only one for the entire day. What are the odds that I am the only one that changes tyres in a work day? It is unlikely. I saw the hideous damage done to the sleeper cab from the explosion, a few nights later.
i had the same thing happen to me less than a year ago. was holding the air chuck on it and i think the tire had a defect or something and it blew right up into my arm and bounced off the roof of our shop, it was so loud i couldn't see or hear anything for about 20 minutes. i'd hate to think what could've happened if i was standing just a few inches closer :(
"Where the hell the rim went?" I just love the way you speak. You seem to have grasped the English slang very well. I can understand you easily. This was me at 12yrs, but on a smaller scale. Thanks so much!
I was driving on a motorway (M6, UK) a few years back when the rear tyre of a tipper truck blew. The car the truck was overtaking suffered a broken side window (and maybe some small cosmetic damage) because the boom dislodged all the dried on clay that was lining the wheelarch. The noise, despite having windows closed and being abot 20m back from the truck, was amazingly loud. Obviously a rigid tipper is a fairly solidly built truck with metal wheel arches and a heavy chassis - there was no obvious damage to the truck and the driver kept it straight and was able to stop safely. And that was all just normal operating pressure (I assume). Also followed one of these trucks as it had a mechanical issue and something obviously jammed the drivetrain - thing stopped dead in the middle lane. I can live to tell the tale because I was keeping a safe distance!
This was quite impressive. If you do this again, I may suggest having a pressure gauge in sight so we can see how much pressure the tire is at and know when it is getting close to critical pressure.
I've experienced 2 tire explosions in my career as an automotive technician, a 16 inch split rim and a 24.5 inch HD tire. Definitely sobering experiences. I appreciated the safety equipment.
I had an E-rated truck tire blow out the sidewall about fifteen seconds after I pulled my hand away from airing it up to 120 PSI. Sounded like a mortar round. If my hand had still been there it would have been blown off.
As a tire technician, I have seen tires explode, especially with split rims, but when the technicians are airing up the tires, they are on their side, laying on the ground. It would be nice to see the explosion with the tire laying down and how high up it actually flies when it explodes, when you walk into a tire shop, take a look at the ceiling for telltale marks, now we have safety cages back then we used chains, but before that we did not have anything. Thank you for putting this on.
I worked at my Dad's gas station in the early 70's, and we didn't have a cage either. Split rims were known to kill people and we never liked doing them. When we did, we'd lower the arms of one of our hoists over the tire and rim to at least prevent it from hitting anyone.
I realize I am replying to myself When we were working on the side of the road on a transport we would wrap chains around the wheels but when you have to keep the split rim from popping out you have to keep going around the tire hitting it with your sledgehammer as you see the metal start to come up you have to hit it back down with the chains wrapped around it it was very hard to do so lots of people chose not to put the chains around it so you could see the ring better as it’s lifting Up
Reply to Ed Nobody knows when a tire is going to explode, it could be from a defect in the tire or with with what we have for safety reasons, But with the split rim, there is a little ring of metal that goes around the inside that tries to hold a bigger ring of metal in place as the tire is being inflated, and you have to keep hammering that little piece to keep it in place as it is airing up, sometimes it don’t work and explodes But I have seen one guy who could not get the rusted metal Apart so he just put the air hose on it and walked away and never told anyone else that was working in the shop. He thought it was funny when the tire exploded, there are.Ass;/&-/s like that everywhere in the world.
@@glennranger4091 Ah ha.... Did not know there was such a thing as a split rim wheel. Googled that, and now I've learned something. That's what it's all about. Thanks!
I got blown up by a rear backhoe tire when i was 19. My 2nd or 3rd near death experience. I didn't know my boss beaded the tire with ether so i was basically adding oxygen to a bomb. I can't explain how i survived. I never heard a bang or felt anything. I was instantly in an oil change pit, somehow completely unharmed. Watching this made all of the hairs on my body stand up and made it even harder to understand the outcome. It removed the roof on the shop and took the drop ceiling down in the office across the street, but somehow i was perfectly fine. I can't explain it. I'm grateful to be able to tell this story. I swear on my life it is a true story. Watching this just adds to my confusion.
Considering the circumstances, I would speculate you were placed in the oil pit by an unseen force moments before the explosion, thus explaining your miraculous survival. I have read other firsthand accounts where people are inexplicably plucked from disaster moments before certain death but cannot explain how it happened. The idea is interdimensional beings intervening on your behalf.😮
It's really crazy. I read some case studies on victims of tyre blowout. Average death rate of 19%. A force equivalent to the detonation of a landmine minus thermal and chemical effects.
I'm an F-15 aircraft maintainer, and in our technical school training we are shown a gruesome picture of "Hamburger Man." He used a method of filling a tire called the "hot shot." Without a pressure regulator or gauge assembly, he used the high pressure (up to 4,000 PSI or 272 BAR I think) side of a nitrogen servicing cart to fill am aircraft tire. He miscalculated and the tire did a rapid unscheduled disassembly, which greatly increased the unfortunate bastard's surface area many times over.
You should try a split rim wheel. They fail more catastrophically. Also, I think if you put a drying tube on the high pressure compressor input, you shouldn't get that cloud that obscures everything. The drop in temperature when the air expands causes the water vapor to condense.
@@mrwilson7617 They're on military vehicles, farm vehicles and industrial vehicles (i.e. not regular road vehicles) all the time. If you look up pictures of HMMWV wheels, they're pretty much all split rims unless the million bolts around the inside of the wheel are for show. (not "humvee" though. the civilian garbage is garbage). But I know what you mean. When I was changing tires a long time ago as a job, I didn't even know they existed until someone brought in a 1950s box truck with left threaded studs on half the wheels. I didn't know left threaded studs existed either.
@@htomerif HMMWV wheels arent a "split rim" in the same sense as the old RH5 where they basically snap-ring together. the HMMWV wheels are a 3 piece double beadlock with a inner, an outer, and a "clamping hoop" for lack of better term. the double beadlock sandwiches both the inner and outer beads positively by having the "clamping hoop" between the two beads when the outer wheel parts are bolted together. with the o-ring between the wheel halves clamping surfaces they dont run tubes and hold air pretty good and can be run offroad down to zero psi without risking losing a bead.
@@bert5003 Yeah, I know. There's two kinds. The kind you're talking about, the locking ring or clamping hoop or whatever its called is only held in place by 8 or 12 bolts or something. The vast, vast, vast majority of HMMWV wheels are the two piece, 24 bolt split rim and the only deviation you're going to see are the ones with the pry bar hole attached. Are they being replaced? Probably. TBH, I have no idea how the ones with the locking ring work or how they fail. At the motorpool I worked in everything had to be put in the inflation cage after assembly.
@@htomerif idk, i got a set of the 24 bolt ones re-centered with custom cut pvc clamping hoops to run on my jeep and theyre pretty solid. i only wish they were a 17" wheel. the big thing though is that the bolt together wheels arent a "split rim" rather a multi-piece wheel. they arent dangerous unless you explicitly start unbolting the halves under pressure. some proper split rim pressure testing for all the danger would be super cool though
Changed my first truck tire at 12 years old, and I have done thousands of tires. Never had one come apart, giving GOD all the thanks for that. Old suicide wheels were probably the most dangerous from a mechanical standpoint. Split rings, 2 and 3 piece. Off-road heavy equipment split rings. I remember a Dart Clark loader at Cottonwood Arizona that had an ejector bucket, 50 ton bucket fulls. I don't remember the tire size, maybe 365/65R35. I know it took half an hour to let the air out the tire.
You might want to look into getting your hands on some rupture discs for the next test. They can tell you definitively whether or not the shock waves themselves are lethal to a human where they're placed.
When I was in my 20's I worked for a repair shop that also did big truck tire's and military vehicle tire's. I was asked if I was willing to help if needed, I said yes. So we had to take a safety class on changing the tires on a 6 and 8 wheeled military vehicle. During that class they showed a video of when the bead of the tire fully seated to the rim, with the tire laying flat on the ground and a Honda Civic sitting on top of it. The Honda jumped about 12 feet into the air!! We had a full steal cage we put the tires into while we aired them up. After 30 or so of those tires, it was trash!! There was an incident with something exploding, but fortunately I was doing my normal job at the time. It sounded like a bomb went off!! Shook the entire building, knocking off dirt and dust from the ceiling. Crazy stuff!!
I sell and repair high pressure breathing air compressors, including Bauer like the one you are using. I have been asked about air chuck attachments for the reels on the systems. While low pressure regulators are available this is a clear demonstration of why I will not install them on systems without those and proper relief safety valves. In an inclosed space this would be even more devastating. Great job!
I can tell you from personal experience, that as simple as blowing up a MTB tire is EXTREMELY loud. Blew up in my face and my ears were ringing for a solid minute after. Almost shattered the windows of the building as well
I worked in a tire shop for a few months years ago. We had a safety cage for inflating split rim tires in, made of very heavy gage tubing. It was notably buckled out from a previous tire explosion. I used it religiously.
I work with an older farmer in the neighborhood. I stopped by one day to see a 60 year old man laughing like a kid. Once I figured out he had an old tractor tire connected to the air compressor on the driveway in front of the shop, with the regulator turned up as far as it would go. The first compressor maxed out at 120 psi, the second compressor maxed out close to 200 psi. It set outside the garage with 200 psi on it for over an hour. When it came apart it shook the barn and probably went 30’ in the air. The tractor tire was an 18.4 x 38 Tractor tire. It was old and dry rotted and all he wanted was the rim for a burn pit ring. Once of the sketchiest things I have ever been around. He wants to try another one in the center of a field with air and propane mix on a fire. Great Video, Thanks from Michigan.

You had me at, "this professional arrangement." Never before have I seen such an excellent demonstration of why a beard net is important. I pity the calendars.
This happened at my 1st job at a lawnmower shop. The service manager, Mack ''The Crack'' was filling a small tractor tire sitting on the bench. He was sitting on a shop stool with his belly up against the bench. He just kept putting more air in, checking pressure by squeezing the tire. My job was to drain the compressor in the basement every morning. So I knew the pressure was 150 psi. About the 3rd time he added more air everybody yelled for him to stop. When he started to put more air in everybody ran. It EXPLODED 💥 Good thing his huge belly put some distance between him and the exploding tire. Dazed and covered with tire debris but not seriously hurt. We then called it ''The Mack Method''. Fill tire till it explodes. Then lower 10 psi.
PSI doesn't sound like much until you start counting all of those inches. A standard house door has about 3,000 sq/in. A nuke has an overpressure wave that does most of the damage and it crushes heavy concrete buildings at 7PSI over atmospheric. That's 21,000 lbs on your front door. Great content guys!!
That first explosion shows that it's not just the force of the blast but where the debris goes. You can see how the tire snags under his arm and around his head, taking them both with it as it continues on.
My comrade friends, I do this with basketball ago many years, yes. Done in a station for refueling of car. Strapped to the basketball was the hose for air. On lever was belt for air to go. Me and good friend stand back and watch ball explode. Very loud. Rubber pieces fly far. Basketball no good for the playing of basketball no more.
My family owned a construction company since the 1970's. In the early 80's an 18yr old kid was changing a split rim and didn't put the safety chains over it. It exploded and decapitated him. My grandfather, who owned the company and was a great man, never forgave himself for the accident even though it wasn't his fault. I'm a mechanic and refuse to do anything with a split rim because of all the horror stories I was told about them growing up.
My father said the same thing to me when I was a kid, don't mess wih split rims, they will kill you. I've always wondered why (because I've seen the Pakistan/India guys go flying up in the air), if the ring is seated properly? I guess the saftey cage is about the best people can do, but both I and you have probably seen these fully inflate only to blow apart while being rolled over to or mounted on the truck. It must be that the ring isn't fully seated, or it's over inflated? I'm not sure but I don't like them either...
@dc6233 Yeah neither do I man. I just have it planted in my brain to leave em alone. That accident happened in 1982 and to this day a piece is stuck in the ceiling of the one garage. Crazy the amount of force that comes from them.
This is a very serious issue for those that inflate tires for a living. Years ago I was at my local pub and two gents were looking very sullen. They just watched their pal get cut in half by a tire that exploded during inflation. No, they did not use the proper guarding.
I personally know a guy who was a mechanic - he had BOTH of his feet severed at the ankle when a truck tire went. He sells wheelchairs now, no joke. Air pressure is the only thing that scares me as much as centrifugal force and that demon electricity.
Its far too easy to get lax about safety because you easily get used to working around very dangerous stuff. I worked in a lumber yard in a millwork shop through HS and college, and at first I was very wary of the machines. After a while they're nothing, you're not intimidated by steel belts with sharp teeth grabbing boards from your hands, not so scared of the giant cross cut saw, etc. At that point you have to fight yourself to always be aware of proper safety, which can be mentally taxing when you're doing work that has become second nature to you.
Former tire tech here, I loved the job but this is something I do not miss. Even for a smaller truck tire, it bows out the cages we used. If they were run flat with no signs of inner casing wear after repair, they typically go boom between 70-85psi.
I don't miss slamming a run flat on the ground, getting the tire bar with lube and jamming it into the bead to break it. Thankfully I survived and never had an accident but what the fuck was I doing man lmfao
A guy was killed where we had our truck tires serviced in the 70's from filling an uncaged two piece rim. I was drawn to this video from that old memory...
I remember about 50 years ago reading about a mechanic who was killed by an exploding tyre he had left on a compressor. The shape of his body was printed in the grime on the garage ceiling.
I used to change and fill tires on split rims in the Airforce for c130s and a10s. We had to put them in a cage before inflating them for obvious reasons. You should try this experiment with a split rim wheel and only use a couple bolts so it will fail. It will be much more devastating than a traditional wheel and tire.
I can confirm this is how it happens irl. I had two semi rims pop off back in my last life, the tire stays and launches the rim across the shop. Both times it happened immediately after checking pressure at 85-90 psi, put chuck back on and turned away, boom. Both also were aluminum rims, the outside lip folded over on both.
Fill the tires with inert gas from welding gas bottles,like Co² so it's not making mist,because there is no moisture in it. There is way enough pressure to blow up tires in those bottles,very fast.
A guy in the next town from here was killed while filling a huge tractor tyre. The force threw him about 15 metres in the air and about 30 metres away. Every organ in his body ruptured with the force. What it did to him was not pretty, necessitating that he had a closed box funeral. That tyre shop now has a reinforced safety cage to accommodate huge tractor tyres as well as updated ones for truck tyres. Respect from South Africa 🇿🇦
@@yankees29 good-ish.. it all depends on how one sees things. A pessimist will see a half tumbler of water as half empty. An optimist sees it half full. A realist will put two shots of whisky and some ice and say "Cheers!" I'm a realist..
A friend of mine worked at a truck shop many years ago. One day a tire for an 18 wheeler exploded (locking ring wasn´t properly seated) it blew out several windows in the shop and also damaged the roof. Luckily they were at lunch break in another building when it happened.
There was an incident at a mine here years ago. One of those massive dump trucks was parked next to a hut, used as a break room. I can't remember the exact specifics but along the lines of the locking ring failed and it was flung at the hut with such force that it more or less demolished it. Fortunately no one was in it at the time. Site rules were updated to state that vehicles must be parked away from the huts and positioned such that if anything went wrong bits would go flying in other directions.
Walking to work one morning a lot of fire and police activity, where the rugby club ; a timber brick and glass structure; used to be was an open space, the building was scattered all over the field. A safety valve on the boiler for the showers had failed , a few hours earlier the club was occupied by a few hundred people at a disco, very lucky indeed.
Simultaneous dual bead break! When servicing aircraft wheels, you must stand to the front or back (treads), not facing the side (axle nut), facing the side when a wheel fails is instant death or dismemberment.
Awesome idea! I have heard/read about the damage exploding bus and truck tires have caused. In those cases, it's usually damaged tires that explode under normal pressure. Get a non damaged tire to explode by overfill it, will make the explosion bigger as the pressure will be much higher when they let go. So i knew this was going to be great!
The scary thing about this video is that around the world there are set ups like this but with real mechanics who end up being a statistic. Great fun video but also educational and could save a life by raising awaeness of the danger of over pressured tyres.
We had a really big and old towmotor forklift where i worked. i think it was from the late 60's, anyway on the front it had 2 wheels per side. Each rim was a split rim and you had to pay attention when changing them because you could see then bolts that held the ri together and the ones that held the wheels on. One day the wheels had to come off because the brake shoes needed relining. We would get younger guys that were in the local universities automotive course to help out around the shop doing cleaning, or oil other small tasks. The boss showed him what bolts to not touch and how to get the forklift set up to get the gear box out and how to lock the forks ram for safety since several lines had to be undone to get to the gear box. i look over 10 minutes later and he has the 1 inch impact, full throttle really struggling to get the wheels off so i go to offer some help and i get about 5 foot away and he has the correct bolts undone but i guess the wheel was stuck and he is loosing the bolts holding the rim together. i grabbed him before he even seen i was walking over and literally drug him as fast as i could around the back of the forklift since the counter weight on the back was like a 4 ton block of cast iron. (not sure of actual weight just saying it was massive.) and asked him what he was doing. he told me the rim was stuck, he had not let any air out of the tires and he figured the boss was joking with him about not taking those bolts out. needles to say we had a bit of a problem. we used video chat to call another cell phone and rigged it onto the end of s pipe and from a distance examined the wheel. kid was lucky the air pressure was so great it made the bolts next to impossible to get undone. of those 5 bolts he got one out completely and the other 4 loosened enough that it had a small gap between the 2 rim halves. we had no idea how to deal with it, or it get it safely deflated, or anything and made some calls. we ended up welding a steel spike onto the bottom of the bucket on an excavator the boss borrowed from his brother and just stabbed the tire of the one wheel. that was when it was decided to get the non split rims they sell for them before anything worse could happen. i know it may seem like we were chickens or way too cautious or what ever but we felt best to be on the safe side. we even called the large local tire shop that does all the heavy equipment and farm implements in the area and the first thing they said was get the hell away from it which we were and that even tho they had a mobile unit for going to farms their would be no way in hell any of their guys would go anywhere near it. they suggested shooting it. that was what led to thinking if we had a long spike to stab it but that would still mean somebody would have to hold it and then the bosses teenage son said we needed a real life transformer and that is how we ended up at an excavator. has anybody else been in any thing like that before or any better ideas?
This is probably my favorite channel on UA-cam. I have yet to be disappointed. Anyway, I’ve seen a 19.5 tow truck tire take out an entire 20’x 20’ garage door. I’m just glad I was on the other side of the building when it happened. Y’all should try the biggest tractor tire you can find or even an old split rim, those things are nasty when the ring comes off. Stay safe and keep em coming, I await my notifications.
I remember about 60 years ago seeing a picture of the aftermath of a tractor tyre doing this somewhere in Italy. The ceiling had the imprint of a farmer, who had forgotten what he was doing, and went back to disconnect the airline.
Jeez, I can only imagine the force an exploding tractor tire would exert. Truck tires are scary enough, but tractor tires are designed to handle absolutely absurd amounts of axle torque so they are built very heavy and thick
@@thecrazyfarmboy Actually I'd much rather be near an exploding tractor tyre. They blow at much lower pressure, mine blew at 40-45 PSI while trying to get the bead to seal properly. Truck tyres handle much higher pressure and are much worse when they blow.
As an AMS in the Navy, the first thing they teach you is AMSs are only afraid of 3 things, tires, ejection seats, and a pink mist. All 3 of them will fk'in kill you.
The energy being produced by the motor running the compressor is being stored inside the tire. When it blows, all that energy is released in a small fraction of a second. It is like when a firecracker explodes. The electrical energy it took to separate the aluminum from the oxygen atoms in the aluminum ore, gets released as heat, as the finely powdered aluminum metal is burned by the oxygen released by the decomposing potassium perchlorate oxidizer, which provides the oxygen to send the aluminum metal back to white aluminum oxide smoke. The 7:3 (by mass) mixture of potassium perchlorate and aluminum powder is quite dangerous to mix, since a static electric spark can ignite it.
The idea the rim in the second one passed *effortlessly* thru the entire bead on the back side, and ripped thru the wall, to leave notable marks in dirt a distance away...
Excellent Video. I once exploded a bicycle tire while inflating it at a gas station. Damaged my eardrum! I can imagine what these explosions sounded like. Great job!
Well buddy, you dodged a bullet there. That stupid stunt has killed quite a few. Spokes become flechettes and can go straight through you. Or anybody stood close. Why would anybody do such a thing?
i used to do this for work before i got injured and had to get out of the trade. i was always EXTREMELY careful while filling up the larger tires. i would love it if you guys could do a loader tire on a 5 piece rim. if you could get your hands on a 23.5R25 or bigger, just to show how absolutely lethal they are when they go off, i would greatly appreciate it! (ive had coworkers brag about using vice grips to hold lock rings in place while airing them up, and it always made me cringe. if any components were ever compromised, i would always install new, instead of risking my life)
BACK IN THE 90'S.... I had a MEGACHAD customer bring me a huge slick that he had mounted by hand but couldn't seat the bead and inflate it. Fortunately, I safely mounted the rim so when the bead broke, I only got a black eye, bruised tailbone, and reminder of why I payed attention in the Safety Class. We became buddies and he turned into a great customer when later, I let him watch me mount a tire properly.
Those truck tires are no joke, even at normal pressures. There's video of a mobster slashing a box truck's tire, and it blew him into the air and shredded his clothes.
This actually serves an important purpose. People often take for granted how dangerous a tire can be if over-inflated. Even a small car tire will tear your face off if you were as close as the mannequin in this video was. Semi tires are like bombs if they explode.
Tyres don't have to be over inflated. If driven at low pressure, the heat can weaken the sidewall and fail when reinflating, especially larger vehicle tyres running over 100psi.
I worked at Sears Auto 20 years ago and whenever we got a tire that had an egg in the sidewall we would put it aside to blow up later at night. It was dangerous as hell but we laughed so fucking hard every time and the sound of the weakened sidewall rupturing was so LOUD. I still remember the first time a coworker intentionally did it during the day and chunky tub (asset protection manager) waddled over from the main store to see what the loud boom was.
"So if anything goes to sheet it doesn't matter" 🤣 I love this channel so much. I'm Canadian so I sound stupid to most of the world but I love Finnish pronunciation of English language.
Another great video! One of your best!. I worked a couple of years in a tire shop. Big truck tire do fail from the rims and side walls. We were required to air them up in a cage. Very dangerous!
Yep. I witnessed the explosion of one truck tire before... It opened a hole in the ceiling of the work shop... (concreted 2 floor building) The flying wheel is like a missile, it is extremely deadly
I had a skidder tire explode beside me just as I turned away from looking at it. It was pushed in off the rim a bit and we had an airline from the logging truck putting air in it. The boss had forgotten to mention the tire gauge sort of stuck at 110 PsI. The truck compressor cutout at 120. It blew the plastic side of the shop out and the cold steam from moisture in the tire completely soaked me through coveralls and clothing. That was close.
This happened to me when i was working in tire shop. Was filling old truck tire and it exploded just before 8 bars. I was not hurt because of safety rules were followed but my ears were ringing for 2 days. Also drywall wall next to the tire moved like 10cm inside. Crazy blast.
Yup. And those were "only" 8 bars. These reached over 45 bars. I'd willing to bet that the pressurewave alone could probably have killed you the first couple of meters.
If you come across some ag tires, I'd use a pressurized cylinder and a dump valve to pre-fill those. It'd also be great to have a way to monitor the areal pressure, like an accelerometer on the tire, or even passive rupture discs that are pierced in air at various psi ratings.
@@joetaylor486 Every safety device can be disabled. If there is a plug, you probably just need something pushing against it from the other side. Or to cover it with tape before the tire is mounted. I do not know how exactly they are built but there is certainly a way to prevent it from preventing an explosion.
The manichean looks like Rasputin. This skit should be used as a Russian version of the Discount Tire Commercials. Instead of an old lady tossing a tire through a shops window we'll just use Rasputin getting blown up by a tire if your not satisfied.
I couldn't stop laughing after the first explosion, it was insanely powerful. Just to show how dangerous these actually can be. A tyre of an airliner would be nice for the next test, these can hold back really high pressures. I have seen a video of one tested inside a bunker and it blew around 90 bar when I remember right.
I bought my daughter a portable electric air pump to keep in her trunk for emergencies. A few months later she had a low tire and insisted she knew how to use the pump without help. After about 10 minutes she came inside and asked me why it was going so slowly. I went to the garage to see what was wrong, the air pump was still on, and looked at the gauge. She had accidentally switched the reading from PSI to BAR. Her 35 PSI tire had 9 BAR in it. I don't think she realized the seriousness of her mistake but I made sure she knew to set the pump to PSI each and EVERY Time before using it again.
@@pappi8338 You really don't know?? Because in the USA we use PSI as a pressure measuement, that's the spec that's molded into the side of the tire, or written in our owners manuals. 9 BAR is well over 100PSI, if a person doesn't know what BAR pressure represents it could get them killed.
PSI never confused me. But, one of my "Nerd" friends is into that BAR, Kilogram, kilometer, meters, liters and all that other foreigner scientist jargon. Pisses me off to no end. But I piss him off with my quarts, Gallons, feet & Yards. So I reckon we're 1-1 on that. Paces are another one that I get him with because 1 pace is roughly 3ft. So 15 paces is 45 feet, give or take a little for terrain. 😁 Converts to like 9 or 12ish meters. I despise the metric system because the bastard spawn of Satan, the 10mm socket is never there. Swear that 10mm socket blips into and out of existence. Schrodinger's 10mm socket. Never where you need it, until you don't. Then it's everywhere.
When I was 16 y.o. I worked at a full serve gas station in Sacramento California. As an inexperience attendant I was tasked with plugging punctured tires and checking tire pressures as requested by customers. One morning a customer in a U-Haul Box Truck asked me to add pressure to the rear (dually type) tires. To reach the inner tire Schrader valve I needed to reach through the hole in the outer rim. While filling the tire it exploded! My ears where ringing from the blast, and my hand felt like I got hit with a bat, Customers from the adjacent businesses rushed out and found me laying confused on the service station driveway. I feel lucky that it was the inner tire that failed and not the outer tire. The manager let me rest for about a half hour then it was business as usual. Back to work. At 53 now I still relive that incident every time I top off a tire.

Try a Boeing 747 tire to explode
you need to glue the tires to the rim so you don't have pressure failure and have actual rubber failure
But you should modify the rim to prewent tire from slipping from it. Then it will be big explosion :)
You guys should put these tires into of a van of some sort and pump them up! Or a car. Those Michelin truck tires are made well!
to shorten the wait you could separate the filling in two stages using different compressors for each, first stage with a compressor that does high volume/low pressure, and only then moving to a low volume/high pressure compressor
This episode brings back bad memories of my first year as a mechanic. I was mounting large truck tires and nobody told me any of the safety rules, so after having mounted a few, using bars no machine, I was tired and was sitting on a tire while filling it. I didn't know that the rim was slightly warped, so it detonated at just over 100psi, sending me (250lbs) up about 4 feet and over 8 feet. The tire hit the shop wall about 30 feet away. I walked away from that with sand blasted eye balls and some bruising, I consider myself very fortunate.
Saw a tire wall failure rip the shirt clean off a mans back. 😂
Vat da fack. Holy shit dude, you're lucky to be alive.
I saw a truck tire explode in a cage.. even in a cage it completely bent up the cage bars.. though the cage did stay together and did stay anchroed to the floor... the blast was so strong just the blast wave broke the window from the office / waiting area of the shop.. it was a standard 11R22.5 tire.. a brand new one.. that particular tech was the only one who used the cages for single piece rims... after that occured the rules were everyone use a cage no matter what tire they were filling.. the consensus was that the exploding tire was defective... they were going up to 115 PSI with it.. the pressure was somewhere between 100 and 115.. the yhad just checled it and it showed 100 then they started ot inflater and boom.. sidewall failure
Very fortunate similar experience with me at a trucking company I had turned to get a drink of water and it sent the rim where I was standing 2 seconds earlier
@@Helo735 Had I been sitting absolutely anywhere else on the tire it would have hit me instead of throwing me. The warped part of the rim was directly under my butt, pointed at the floor.

0where did the truck wheel end up?????😱😱😱😱
I inflate 22.5" tires at work, I put it in a safety cage, use air regulated to 125 psi, and I walk away and work on things on the other side of the shop for about 15 minutes. This here is a great demonstration of why I do it this way.
In 1971 my father was working in a tire shop on a set of split rim truck tires when on of them blue apart. He had not secured the locking ring properly. It tore 3 fingers off of hie left hand and broke 7 ribs. Two had multiple fractures. He also had severe bruising on the entire front of his body and lost the earlobe on his left ear. Somehow his hearing recovered and his eyes were not damaged. He was told by the insurance people he was one of the lucky 1 in ten that actually survive that kind of accident. Most people are bending over the tire assembly when they blow. He had stood up and was turning to walk away when all hell cut loose. Thanks for demonstrating the incredible raw power released when these things go wrong.

@@johngibson3837 That's what you do now. This guy's father was doing it in 1971. Your comment is irrelevant.
I had to watch this! About 55 years ago I was mounting a 15 inch garden tractor tire on a rim so I could use it on a home made dune buggy. I was kneeling down on a concrete driveway and holding the air chuck on the valve stem. Really don't know how much pressure went in, but the bead cable/wire broke in the bottom bead of the tire. The rim and wheel went straight up in the air through an aluminum car port and probably about 20 feet higher. I was stunned and when I came to my senses I was watching the tire and wheel come back down and bounce off the hood of my '62 Chevy p/u. Then I realized I was standing where I had been kneeling and I was holding my right arm with my left hand. Both bones in my forearm were shattered and had to have surgery with pins implanted. This is entertaining to watch, but not to live through. Everyone should be really careful with tires and air pressure. I'm very thankful I was not decapitated or killed!
A man that went to my congregation had his arm blown off by this very same thing! I never talked to him because I was just a teenager, but that was what I had heard what happened to him... 😩
Wow thank god you survived. That’s some crazy shyt!!!😮
Thank you for sharing your experience. A day shift worker, about five years back died because of a tyre explosion. It is rather a comfort that he likely felt nothing. I saw the damage it did to the Few use the tyre cage. It has to be signed out to get it out of the equipment room, as all the heavy duty equipment had to be. Often, my signature is the only one for the entire day. What are the odds that I am the only one that changes tyres in a work day? It is unlikely. I saw the hideous damage done to the sleeper cab from the explosion, a few nights later.
i had the same thing happen to me less than a year ago. was holding the air chuck on it and i think the tire had a defect or something and it blew right up into my arm and bounced off the roof of our shop, it was so loud i couldn't see or hear anything for about 20 minutes. i'd hate to think what could've happened if i was standing just a few inches closer :(
Yeah there's no way you could be thankful if you were dead.

“If anything goes to shite… it doesn’t matter” truer words have never been spoken.
"Where the hell the rim went?" I just love the way you speak. You seem to have grasped the English slang very well. I can understand you easily. This was me at 12yrs, but on a smaller scale. Thanks so much!
What you should do is do this while the tires are on a vehicle and see what it does to the car/truck.
How about inside a car?
I was driving on a motorway (M6, UK) a few years back when the rear tyre of a tipper truck blew. The car the truck was overtaking suffered a broken side window (and maybe some small cosmetic damage) because the boom dislodged all the dried on clay that was lining the wheelarch. The noise, despite having windows closed and being abot 20m back from the truck, was amazingly loud.
Obviously a rigid tipper is a fairly solidly built truck with metal wheel arches and a heavy chassis - there was no obvious damage to the truck and the driver kept it straight and was able to stop safely. And that was all just normal operating pressure (I assume).
Also followed one of these trucks as it had a mechanical issue and something obviously jammed the drivetrain - thing stopped dead in the middle lane. I can live to tell the tale because I was keeping a safe distance!
Slight annoying damage and nothing else.
Put it inside of car!!
Like NASCAR, tears up bodywork, although composites used now, much less damage.
This was quite impressive. If you do this again, I may suggest having a pressure gauge in sight so we can see how much pressure the tire is at and know when it is getting close to critical pressure.
I've experienced 2 tire explosions in my career as an automotive technician, a 16 inch split rim and a 24.5 inch HD tire. Definitely sobering experiences. I appreciated the safety equipment.
Split rims scare the crap out of me.
(40.64cm and 62.23cm)
@@pappi8338 Rim sizes are measured in inches (R14, R15, etc) while the tyre/tire width (fatness) is measured in mm.
I had an E-rated truck tire blow out the sidewall about fifteen seconds after I pulled my hand away from airing it up to 120 PSI. Sounded like a mortar round. If my hand had still been there it would have been blown off.
As a tire technician, I have seen tires explode, especially with split rims, but when the technicians are airing up the tires, they are on their side, laying on the ground. It would be nice to see the explosion with the tire laying down and how high up it actually flies when it explodes, when you walk into a tire shop, take a look at the ceiling for telltale marks, now we have safety cages back then we used chains, but before that we did not have anything. Thank you for putting this on.
I worked at my Dad's gas station in the early 70's, and we didn't have a cage either. Split rims were known to kill people and we never liked doing them. When we did, we'd lower the arms of one of our hoists over the tire and rim to at least prevent it from hitting anyone.
I realize I am replying to myself When we were working on the side of the road on a transport we would wrap chains around the wheels but when you have to keep the split rim from popping out you have to keep going around the tire hitting it with your sledgehammer as you see the metal start to come up you have to hit it back down with the chains wrapped around it it was very hard to do so lots of people chose not to put the chains around it so you could see the ring better as it’s lifting Up
As a non-tire technician, why are you even filling a tire to the point of explosion?
Reply to Ed
Nobody knows when a tire is going to explode, it could be from a defect in the tire or with with what we have for safety reasons,
But with the split rim, there is a little ring of metal that goes around the inside that tries to hold a bigger ring of metal in place as the tire is being inflated, and you have to keep hammering that little piece to keep it in place as it is airing up, sometimes it don’t work and explodes
But I have seen one guy who could not get the rusted metal Apart so he just put the air hose on it and walked away and never told anyone else that was working in the shop. He thought it was funny when the tire exploded, there are.Ass;/&-/s like that everywhere in the world.
@@glennranger4091 Ah ha.... Did not know there was such a thing as a split rim wheel. Googled that, and now I've learned something. That's what it's all about. Thanks!
I got blown up by a rear backhoe tire when i was 19. My 2nd or 3rd near death experience. I didn't know my boss beaded the tire with ether so i was basically adding oxygen to a bomb. I can't explain how i survived. I never heard a bang or felt anything. I was instantly in an oil change pit, somehow completely unharmed. Watching this made all of the hairs on my body stand up and made it even harder to understand the outcome. It removed the roof on the shop and took the drop ceiling down in the office across the street, but somehow i was perfectly fine. I can't explain it. I'm grateful to be able to tell this story. I swear on my life it is a true story. Watching this just adds to my confusion.
Considering the circumstances, I would speculate you were placed in the oil pit by an unseen force moments before the explosion, thus explaining your miraculous survival. I have read other firsthand accounts where people are inexplicably plucked from disaster moments before certain death but cannot explain how it happened. The idea is interdimensional beings intervening on your behalf.😮

It's really crazy. I read some case studies on victims of tyre blowout. Average death rate of 19%. A force equivalent to the detonation of a landmine minus thermal and chemical effects.
I'm an F-15 aircraft maintainer, and in our technical school training we are shown a gruesome picture of "Hamburger Man." He used a method of filling a tire called the "hot shot." Without a pressure regulator or gauge assembly, he used the high pressure (up to 4,000 PSI or 272 BAR I think) side of a nitrogen servicing cart to fill am aircraft tire. He miscalculated and the tire did a rapid unscheduled disassembly, which greatly increased the unfortunate bastard's surface area many times over.
As a former 2A672 that maintained those SGNSC's, this checks out. Hamburger Man is real.

The obvious next step is a quarry truck tyre. Those really aren't cheap though!
Maybe get a scrap one that's worn too thin to be fixed?
A farm tractor tire would be a nice in-between step, and those are very cheap.
Scrap ones can hold air still definitely! buying a new tire would not be worth it at all.
@@fxui Of course. But even the scrap ones are expensive, and you'll need a rim as well.
Tractor tires could be a good intermediate.
You should try a split rim wheel. They fail more catastrophically.
Also, I think if you put a drying tube on the high pressure compressor input, you shouldn't get that cloud that obscures everything. The drop in temperature when the air expands causes the water vapor to condense.
Only split rims I see are on decommissioned box trailers used for storage.
@@mrwilson7617 They're on military vehicles, farm vehicles and industrial vehicles (i.e. not regular road vehicles) all the time. If you look up pictures of HMMWV wheels, they're pretty much all split rims unless the million bolts around the inside of the wheel are for show. (not "humvee" though. the civilian garbage is garbage).
But I know what you mean. When I was changing tires a long time ago as a job, I didn't even know they existed until someone brought in a 1950s box truck with left threaded studs on half the wheels. I didn't know left threaded studs existed either.
@@htomerif HMMWV wheels arent a "split rim" in the same sense as the old RH5 where they basically snap-ring together. the HMMWV wheels are a 3 piece double beadlock with a inner, an outer, and a "clamping hoop" for lack of better term. the double beadlock sandwiches both the inner and outer beads positively by having the "clamping hoop" between the two beads when the outer wheel parts are bolted together. with the o-ring between the wheel halves clamping surfaces they dont run tubes and hold air pretty good and can be run offroad down to zero psi without risking losing a bead.
@@bert5003 Yeah, I know. There's two kinds. The kind you're talking about, the locking ring or clamping hoop or whatever its called is only held in place by 8 or 12 bolts or something. The vast, vast, vast majority of HMMWV wheels are the two piece, 24 bolt split rim and the only deviation you're going to see are the ones with the pry bar hole attached.
Are they being replaced? Probably. TBH, I have no idea how the ones with the locking ring work or how they fail.
At the motorpool I worked in everything had to be put in the inflation cage after assembly.
@@htomerif idk, i got a set of the 24 bolt ones re-centered with custom cut pvc clamping hoops to run on my jeep and theyre pretty solid. i only wish they were a 17" wheel.
the big thing though is that the bolt together wheels arent a "split rim" rather a multi-piece wheel. they arent dangerous unless you explicitly start unbolting the halves under pressure. some proper split rim pressure testing for all the danger would be super cool though
Changed my first truck tire at 12 years old, and I have done thousands of tires. Never had one come apart, giving GOD all the thanks for that. Old suicide wheels were probably the most dangerous from a mechanical standpoint. Split rings, 2 and 3 piece. Off-road heavy equipment split rings. I remember a Dart Clark loader at Cottonwood Arizona that had an ejector bucket, 50 ton bucket fulls. I don't remember the tire size, maybe 365/65R35. I know it took half an hour to let the air out the tire.
This was a great collaboration... Sean from Bikes and Beards was pretty brave for holding those tires like that.

When I was in my 20's I worked for a repair shop that also did big truck tire's and military vehicle tire's. I was asked if I was willing to help if needed, I said yes. So we had to take a safety class on changing the tires on a 6 and 8 wheeled military vehicle. During that class they showed a video of when the bead of the tire fully seated to the rim, with the tire laying flat on the ground and a Honda Civic sitting on top of it. The Honda jumped about 12 feet into the air!! We had a full steal cage we put the tires into while we aired them up. After 30 or so of those tires, it was trash!! There was an incident with something exploding, but fortunately I was doing my normal job at the time. It sounded like a bomb went off!! Shook the entire building, knocking off dirt and dust from the ceiling. Crazy stuff!!
I sell and repair high pressure breathing air compressors, including Bauer like the one you are using. I have been asked about air chuck attachments for the reels on the systems. While low pressure regulators are available this is a clear demonstration of why I will not install them on systems without those and proper relief safety valves. In an inclosed space this would be even more devastating. Great job!
I can tell you from personal experience, that as simple as blowing up a MTB tire is EXTREMELY loud. Blew up in my face and my ears were ringing for a solid minute after. Almost shattered the windows of the building as well
I worked in a tire shop for a few months years ago. We had a safety cage for inflating split rim tires in, made of very heavy gage tubing. It was notably buckled out from a previous tire explosion. I used it religiously.
I work with an older farmer in the neighborhood. I stopped by one day to see a 60 year old man laughing like a kid. Once I figured out he had an old tractor tire connected to the air compressor on the driveway in front of the shop, with the regulator turned up as far as it would go. The first compressor maxed out at 120 psi, the second compressor maxed out close to 200 psi. It set outside the garage with 200 psi on it for over an hour. When it came apart it shook the barn and probably went 30’ in the air. The tractor tire was an 18.4 x 38 Tractor tire. It was old and dry rotted and all he wanted was the rim for a burn pit ring. Once of the sketchiest things I have ever been around. He wants to try another one in the center of a field with air and propane mix on a fire. Great Video, Thanks from Michigan.

This happened at my 1st job at a lawnmower shop. The service manager, Mack ''The Crack'' was filling a small tractor tire sitting on the bench. He was sitting on a shop stool with his belly up against the bench. He just kept putting more air in, checking pressure by squeezing the tire. My job was to drain the compressor in the basement every morning. So I knew the pressure was 150 psi. About the 3rd time he added more air everybody yelled for him to stop. When he started to put more air in everybody ran. It EXPLODED 💥 Good thing his huge belly put some distance between him and the exploding tire. Dazed and covered with tire debris but not seriously hurt. We then called it ''The Mack Method''. Fill tire till it explodes. Then lower 10 psi.
PSI doesn't sound like much until you start counting all of those inches. A standard house door has about 3,000 sq/in.

My family owned a construction company since the 1970's. In the early 80's an 18yr old kid was changing a split rim and didn't put the safety chains over it. It exploded and decapitated him. My grandfather, who owned the company and was a great man, never forgave himself for the accident even though it wasn't his fault. I'm a mechanic and refuse to do anything with a split rim because of all the horror stories I was told about them growing up.
My father said the same thing to me when I was a kid, don't mess wih split rims, they will kill you. I've always wondered why (because I've seen the Pakistan/India guys go flying up in the air), if the ring is seated properly? I guess the saftey cage is about the best people can do, but both I and you have probably seen these fully inflate only to blow apart while being rolled over to or mounted on the truck. It must be that the ring isn't fully seated, or it's over inflated? I'm not sure but I don't like them either...

Its far too easy to get lax about safety because you easily get used to working around very dangerous stuff. I worked in a lumber yard in a millwork shop through HS and college, and at first I was very wary of the machines. After a while they're nothing, you're not intimidated by steel belts with sharp teeth grabbing boards from your hands, not so scared of the giant cross cut saw, etc. At that point you have to fight yourself to always be aware of proper safety, which can be mentally taxing when you're doing work that has become second nature to you.
Former tire tech here, I loved the job but this is something I do not miss. Even for a smaller truck tire, it bows out the cages we used. If they were run flat with no signs of inner casing wear after repair, they typically go boom between 70-85psi.
I don't miss slamming a run flat on the ground, getting the tire bar with lube and jamming it into the bead to break it. Thankfully I survived and never had an accident but what the fuck was I doing man lmfao
@intruative hey man we all had to start somewhere, it was a fun job, took out alot of anger swinging that duck bill.
A guy was killed where we had our truck tires serviced in the 70's from filling an uncaged two piece rim. I was drawn to this video from that old memory...
I remember about 50 years ago reading about a mechanic who was killed by an exploding tyre he had left on a compressor. The shape of his body was printed in the grime on the garage ceiling.
I used to change and fill tires on split rims in the Airforce for c130s and a10s. We had to put them in a cage before inflating them for obvious reasons. You should try this experiment with a split rim wheel and only use a couple bolts so it will fail. It will be much more devastating than a traditional wheel and tire.
They need to pick up some used military surplus airplane tires. I can’t imagine what those are designed to resist!
Wow those are my two favorite military aircraft. Ty for your service to our country. You literally made the wheels spin!😂
07:43 everyone sing along ... 'you picked a fine time to leave me loose-wheel'
I can't imagine a better vacation than doing stuff like this. Thank you so much for the video!!!
I can confirm this is how it happens irl. I had two semi rims pop off back in my last life, the tire stays and launches the rim across the shop. Both times it happened immediately after checking pressure at 85-90 psi, put chuck back on and turned away, boom. Both also were aluminum rims, the outside lip folded over on both.
Fill the tires with inert gas from welding gas bottles,like Co² so it's not making mist,because there is no moisture in it.
There is way enough pressure to blow up tires in those bottles,very fast.
A guy in the next town from here was killed while filling a huge tractor tyre. The force threw him about 15 metres in the air and about 30 metres away. Every organ in his body ruptured with the force. What it did to him was not pretty, necessitating that he had a closed box funeral.
That tyre shop now has a reinforced safety cage to accommodate huge tractor tyres as well as updated ones for truck tyres.

A friend of mine worked at a truck shop many years ago. One day a tire for an 18 wheeler exploded (locking ring wasn´t properly seated) it blew out several windows in the shop and also damaged the roof. Luckily they were at lunch break in another building when it happened.
There was an incident at a mine here years ago. One of those massive dump trucks was parked next to a hut, used as a break room. I can't remember the exact specifics but along the lines of the locking ring failed and it was flung at the hut with such force that it more or less demolished it. Fortunately no one was in it at the time. Site rules were updated to state that vehicles must be parked away from the huts and positioned such that if anything went wrong bits would go flying in other directions.
They were fortunate, safety regulations are all too often written in blood.
Walking to work one morning a lot of fire and police activity, where the rugby club ; a timber brick and glass structure; used to be was an open space, the building was scattered all over the field. A safety valve on the boiler for the showers had failed , a few hours earlier the club was occupied by a few hundred people at a disco, very lucky indeed.
If you have to call any structure a "hut", you already know you're in danger 🤣
Simultaneous dual bead break!
When servicing aircraft wheels, you must stand to the front or back (treads), not facing the side (axle nut), facing the side when a wheel fails is instant death or dismemberment.
Great training and educational video on airing tire safety. This is why tire cage is important for safety purposes.
I did not expect the rim to just go flying like that. But with the second tire the air blast actually blew out the wall before the rim could hit it.
Are you sure you want to quit without saving? 📎
Awesome idea!
I have heard/read about the damage exploding bus and truck tires have caused. In those cases, it's usually damaged tires that explode under normal pressure. Get a non damaged tire to explode by overfill it, will make the explosion bigger as the pressure will be much higher when they let go. So i knew this was going to be great!
Or undoing the wrong bolts on a split rim.
lauri this was one of your best ideas ever
Man that is scary shit. I had no idea the damage a tire exploding off a rim could do. Thanks for the enlightening info.
3:43 even the compressor was laughing. 😆
The scary thing about this video is that around the world there are set ups like this but with real mechanics who end up being a statistic. Great fun video but also educational and could save a life by raising awaeness of the danger of over pressured tyres.
The worker was so dedicated he even tried to stop the tire from rolling away after the explosion. Impressing!
Hard to get good help like that. Especially conscientious employee! 😂
Aaron Kaufman would do nothing less...
3:35 This is the ONE time EVER where the normal speed is BETTER than the high speed!!!
We had a really big and old towmotor forklift where i worked. i think it was from the late 60's, anyway on the front it had 2 wheels per side. Each rim was a split rim and you had to pay attention when changing them because you could see then bolts that held the ri together and the ones that held the wheels on. One day the wheels had to come off because the brake shoes needed relining. We would get younger guys that were in the local universities automotive course to help out around the shop doing cleaning, or oil other small tasks. The boss showed him what bolts to not touch and how to get the forklift set up to get the gear box out and how to lock the forks ram for safety since several lines had to be undone to get to the gear box. i look over 10 minutes later and he has the 1 inch impact, full throttle really struggling to get the wheels off so i go to offer some help and i get about 5 foot away and he has the correct bolts undone but i guess the wheel was stuck and he is loosing the bolts holding the rim together. i grabbed him before he even seen i was walking over and literally drug him as fast as i could around the back of the forklift since the counter weight on the back was like a 4 ton block of cast iron. (not sure of actual weight just saying it was massive.) and asked him what he was doing. he told me the rim was stuck, he had not let any air out of the tires and he figured the boss was joking with him about not taking those bolts out. needles to say we had a bit of a problem. we used video chat to call another cell phone and rigged it onto the end of s pipe and from a distance examined the wheel. kid was lucky the air pressure was so great it made the bolts next to impossible to get undone. of those 5 bolts he got one out completely and the other 4 loosened enough that it had a small gap between the 2 rim halves. we had no idea how to deal with it, or it get it safely deflated, or anything and made some calls. we ended up welding a steel spike onto the bottom of the bucket on an excavator the boss borrowed from his brother and just stabbed the tire of the one wheel. that was when it was decided to get the non split rims they sell for them before anything worse could happen. i know it may seem like we were chickens or way too cautious or what ever but we felt best to be on the safe side. we even called the large local tire shop that does all the heavy equipment and farm implements in the area and the first thing they said was get the hell away from it which we were and that even tho they had a mobile unit for going to farms their would be no way in hell any of their guys would go anywhere near it. they suggested shooting it. that was what led to thinking if we had a long spike to stab it but that would still mean somebody would have to hold it and then the bosses teenage son said we needed a real life transformer and that is how we ended up at an excavator. has anybody else been in any thing like that before or any better ideas?
This is probably my favorite channel on UA-cam. I have yet to be disappointed. Anyway, I’ve seen a 19.5 tow truck tire take out an entire 20’x 20’ garage door. I’m just glad I was on the other side of the building when it happened. Y’all should try the biggest tractor tire you can find or even an old split rim, those things are nasty when the ring comes off. Stay safe and keep em coming, I await my notifications.
I remember about 60 years ago seeing a picture of the aftermath of a tractor tyre doing this somewhere in Italy. The ceiling had the imprint of a farmer, who had forgotten what he was doing, and went back to disconnect the airline.
Jeez, I can only imagine the force an exploding tractor tire would exert. Truck tires are scary enough, but tractor tires are designed to handle absolutely absurd amounts of axle torque so they are built very heavy and thick
That is not the way I want to leave my mark.
@@thecrazyfarmboy Actually I'd much rather be near an exploding tractor tyre. They blow at much lower pressure, mine blew at 40-45 PSI while trying to get the bead to seal properly. Truck tyres handle much higher pressure and are much worse when they blow.
I remember that, it looked like a shadow.
I used to be a semi mechanic and was told a similar story. Guy was leaning over a split rim and it blew. His body was imprinted in the ceiling.
That pipe stand you made couple years ago has stood up well to many explosions. Prrriiti Guud. 👍
It has seen a lot :D
And this is why you do pressure tests with water and not air 💥
I think we have to also test some steel containers :D
@@Beyondthepresssee if you can explode a BBQ gas cylinder.
@@Beyondthepress Easiest way to do that would probably be to ad water and heat it till it blows! 😎

Again, a good experiment with explosions. Thanks.
As an AMS in the Navy, the first thing they teach you is AMSs are only afraid of 3 things, tires, ejection seats, and a pink mist. All 3 of them will fk'in kill you.
It's terrifying how much energy is released when those tires fail.
The energy being produced by the motor running the compressor is being stored inside the tire. When it blows, all that energy is released in a small fraction of a second. It is like when a firecracker explodes. The electrical energy it took to separate the aluminum from the oxygen atoms in the aluminum ore, gets released as heat, as the finely powdered aluminum metal is burned by the oxygen released by the decomposing potassium perchlorate oxidizer, which provides the oxygen to send the aluminum metal back to white aluminum oxide smoke. The 7:3 (by mass) mixture of potassium perchlorate and aluminum powder is quite dangerous to mix, since a static electric spark can ignite it.
Not at all to me....
The idea the rim in the second one passed *effortlessly* thru the entire bead on the back side, and ripped thru the wall, to leave notable marks in dirt a distance away...
@@billsimpson604thanks nerd.

Excellent Video. I once exploded a bicycle tire while inflating it at a gas station. Damaged my eardrum! I can imagine what these explosions sounded like. Great job!
Well buddy, you dodged a bullet there. That stupid stunt has killed quite a few. Spokes become flechettes and can go straight through you. Or anybody stood close. Why would anybody do such a thing?
I did the same thing when I was a young-ling... I failed to understand that the pressure gauge did not read the internal pressure while inflating.
Me too. Young enough to not know tire inflators put out WAY more pressure than a 10 speed pump.
Long walk home too.
i used to do this for work before i got injured and had to get out of the trade. i was always EXTREMELY careful while filling up the larger tires. i would love it if you guys could do a loader tire on a 5 piece rim. if you could get your hands on a 23.5R25 or bigger, just to show how absolutely lethal they are when they go off, i would greatly appreciate it! (ive had coworkers brag about using vice grips to hold lock rings in place while airing them up, and it always made me cringe. if any components were ever compromised, i would always install new, instead of risking my life)
BACK IN THE 90'S.... I had a MEGACHAD customer bring me a huge slick that he had mounted by hand but couldn't seat the bead and inflate it. Fortunately, I safely mounted the rim so when the bead broke, I only got a black eye, bruised tailbone, and reminder of why I payed attention in the Safety Class. We became buddies and he turned into a great customer when later, I let him watch me mount a tire properly.
Good times 😅
TIL that I shouldn't inflate my car tires to 700psi. I'll keep them at 500psi in the future to be safe.
Those truck tires are no joke, even at normal pressures. There's video of a mobster slashing a box truck's tire, and it blew him into the air and shredded his clothes.
I was maybe 6m away on a footpath when one blew out on a multi wheel trailer going past, and that was loud enough.
This actually serves an important purpose. People often take for granted how dangerous a tire can be if over-inflated. Even a small car tire will tear your face off if you were as close as the mannequin in this video was. Semi tires are like bombs if they explode.
Tyres don't have to be over inflated. If driven at low pressure, the heat can weaken the sidewall and fail when reinflating, especially larger vehicle tyres running over 100psi.
I worked at Sears Auto 20 years ago and whenever we got a tire that had an egg in the sidewall we would put it aside to blow up later at night. It was dangerous as hell but we laughed so fucking hard every time and the sound of the weakened sidewall rupturing was so LOUD. I still remember the first time a coworker intentionally did it during the day and chunky tub (asset protection manager) waddled over from the main store to see what the loud boom was.
"So if anything goes to sheet it doesn't matter" 🤣 I love this channel so much. I'm Canadian so I sound stupid to most of the world but I love Finnish pronunciation of English language.
Another great video! One of your best!. I worked a couple of years in a tire shop. Big truck tire do fail from the rims and side walls. We were required to air them up in a cage. Very dangerous!
If you try this again, you should get some burst discs and place them at several distances to see how far away someone would have to be to survive.
Yep. I witnessed the explosion of one truck tire before... It opened a hole in the ceiling of the work shop... (concreted 2 floor building) The flying wheel is like a missile, it is extremely deadly
I had a skidder tire explode beside me just as I turned away from looking at it. It was pushed in off the rim a bit and we had an airline from the logging truck putting air in it. The boss had forgotten to mention the tire gauge sort of stuck at 110 PsI. The truck compressor cutout at 120. It blew the plastic side of the shop out and the cold steam from moisture in the tire completely soaked me through coveralls and clothing. That was close.
This happened to me when i was working in tire shop. Was filling old truck tire and it exploded just before 8 bars. I was not hurt because of safety rules were followed but my ears were ringing for 2 days. Also drywall wall next to the tire moved like 10cm inside. Crazy blast.
Yup.
And those were "only" 8 bars.
These reached over 45 bars. I'd willing to bet that the pressurewave alone could probably have killed you the first couple of meters.
116 psi. is that the normal pressure for that tire, or was there some kind of regulator failure?
@@itoibo4208116?
What a treat ! Greetings and love from Boston, Massachusetts.
There was actually coffee in the Starbucks cups on the table. That kind of attention to detail is exactly why I love this channel.
If you come across some ag tires, I'd use a pressurized cylinder and a dump valve to pre-fill those. It'd also be great to have a way to monitor the areal pressure, like an accelerometer on the tire, or even passive rupture discs that are pierced in air at various psi ratings.
Aircraft tyre/wheel? Airliner tyres are run at pressures up to 400 psi in service. I bet they can take a whole lot more before they give up!
Aircraft stuff often has a lower safety factor tho.
And will be replaced much more often..good idea.
The rims have plugs in them. The plugs leave on an over pressure and melt during a hard brake application like during an aborted take off
@@theairstig9164 fair point. Hmm maybe this safety device could be defeated?
@@joetaylor486 Every safety device can be disabled. If there is a plug, you probably just need something pushing against it from the other side. Or to cover it with tape before the tire is mounted. I do not know how exactly they are built but there is certainly a way to prevent it from preventing an explosion.
Please... A moment of silence for the calendars....
The manichean looks like Rasputin. This skit should be used as a Russian version of the Discount Tire Commercials. Instead of an old lady tossing a tire through a shops window we'll just use Rasputin getting blown up by a tire if your not satisfied.
I expected the truck rim to split in half after I saw that happening in another video.
An idea for the next tire exploding video: have one camera up somewhere high so we can see where the rims are flying :D
I couldn't stop laughing after the first explosion, it was insanely powerful. Just to show how dangerous these actually can be.
A tyre of an airliner would be nice for the next test, these can hold back really high pressures.
I have seen a video of one tested inside a bunker and it blew around 90 bar when I remember right.
I bought my daughter a portable electric air pump to keep in her trunk for emergencies. A few months later she had a low tire and insisted she knew how to use the pump without help. After about 10 minutes she came inside and asked me why it was going so slowly. I went to the garage to see what was wrong, the air pump was still on, and looked at the gauge. She had accidentally switched the reading from PSI to BAR. Her 35 PSI tire had 9 BAR in it. I don't think she realized the seriousness of her mistake but I made sure she knew to set the pump to PSI each and EVERY Time before using it again.
Why would you set it to PSI?
@@pappi8338 You really don't know?? Because in the USA we use PSI as a pressure measuement, that's the spec that's molded into the side of the tire, or written in our owners manuals. 9 BAR is well over 100PSI, if a person doesn't know what BAR pressure represents it could get them killed.
PSI never confused me. But, one of my "Nerd" friends is into that BAR, Kilogram, kilometer, meters, liters and all that other foreigner scientist jargon.
Pisses me off to no end. But I piss him off with my quarts, Gallons, feet & Yards. So I reckon we're 1-1 on that.
Paces are another one that I get him with because 1 pace is roughly 3ft. So 15 paces is 45 feet, give or take a little for terrain. 😁 Converts to like 9 or 12ish meters.
I despise the metric system because the bastard spawn of Satan, the 10mm socket is never there. Swear that 10mm socket blips into and out of existence. Schrodinger's 10mm socket. Never where you need it, until you don't. Then it's everywhere.
When I was 16 y.o. I worked at a full serve gas station in Sacramento California. As an inexperience attendant I was tasked with plugging punctured tires and checking tire pressures as requested by customers. One morning a customer in a U-Haul Box Truck asked me to add pressure to the rear (dually type) tires. To reach the inner tire Schrader valve I needed to reach through the hole in the outer rim. While filling the tire it exploded! My ears where ringing from the blast, and my hand felt like I got hit with a bat, Customers from the adjacent businesses rushed out and found me laying confused on the service station driveway. I feel lucky that it was the inner tire that failed and not the outer tire. The manager let me rest for about a half hour then it was business as usual. Back to work. At 53 now I still relive that incident every time I top off a tire.
This guy is great. He takes the stuff that the kids do on you tube, way up to an adult level. Serious business for sure. Great video and you have a new subscriber! Thank you. J Poll.
I wanna see more different types of Tyres. like different Bike Tyres, Kart, Motorbike, Dirtbike, Kidsbikes... etc. that would be nice.
You can pop those yourself with an ordinary pump (takes about 15 minutes). I did it before by accident (it kicked my shoe). XD
He is obviously balancing the tire 😂
