Been working aircraft since 1978. 23 years military and the rest as a certified A&P AMT. There is no such thing as an emergency tire repair. You change the damn thing and be done with it.
So true. There have been dangerous times with tires. always deflate the tire. Some dangerous times. When wheel half bolt fail. When enough bolts fail the wheel will burst when the axel nut is released. Or when the bead edge cracks the tire could jump the rim. I have seen a mechanic remove the shrader valve. I did not have that nerve. I would get the spike.
@@jayreiter268 I don't like to remove the valve either, way too noisy. I made a tool, I just screw a screw in a cap and drill 2 holes in the side to let the N2 escape. Work fine.
Where to start? "Solid tires" means non -pneumatic, not used on aircraft. No airplane has payload of 250 tons. Somebody does not understand the difference between aircraft gross weight, useful weight, and payload. Impact on landing is not a major factor in tire wear. The highest stress on an aircraft tire occurs on takeoff roll, and most tire wear occurs during braking after touchdown. I have never heard of tire replacement rules based on number of landings. Aircraft tires are probably the most common example of what is known as on-condition replacement. It may need replacement after one landing, but usually it is tread wear limits, flat spots from skids or hydroplaning, low pressure, cracks in sidewall, or even having been on the same axle as another tire that was found to be at low pressure, increasing the load on the remaining wheel. In the real world, a tire may continue in service for an extra day after reaching the tread wear limits because the mechanic has a hangover or does not want to change a tire in sub-zero temperatures. "Rupture during touchdown" is going to occur only if the tire is damaged or at low pressure OR the touchdown was so severe that the whole airframe will have to be inspected for damage. Once again, the tires are under maximum stress at takeoff, not landing. Aircraft wheels do not "bolt to struts." They typically contain bearings that slide onto the axle, and are retained by a threaded nut on the end of the axle. On many aircraft, the axle is not an integral part of the strut, but is clamped into a boss in the strut. On trains, wheel screech is caused by friction between wheel flanges and rails on curved sections of track. Flat spots on tires (yes, steel tires are still tires) cause an obvious thump-thump sound as the wheel rolls.
I'm a locomotive engineer for a large US railroad, and you are 100% correct about train wheels. I came here to say what you said, but you beat me to it haha
Well, the An-225 could actually take 254 tonnes of cargo but a few weeks ago, the only aircraft of its kind was destroyed by the damn Russians so now you are right about that.
As a licensed American A&P Mechanic I can honestly say that in my 30+ years of Aircraft Maintenance, I have NEVER ONCE "repaired" an aircraft TIRE!!! AND, it's just not done! The tire is either "good to go" , OR you replace it!!!
Even someone only going through any decent A&P program should be able to tell you that. The only time any aircraft tires are "repaired" are when the manufacturer is doing a refurb, similar to how props are serviced. Very very few general mechanics will "repair" a tire or prop even though we are technically allowed to, unless you work at a specialized facilty. I've replaced quite a few tires, depending on where/what you work and the owner/operators wishes, sometimes you might replace only the tire and keep the wheel or replace the entire wheel assembly
As an EASA licensed engineer I can confirm that. Aircraft maintenance is performed under part 145 while the repair of components is performed under part 21 subpart G. We are not allowed to preform any repairs on components, we can only replace them with new or refurbished ones.
Flats on train wheels occur when the wheel is locked by a brake, and the car is dragged along the track. It makes a distinctive “bam, bam!” When the brake is released and the flattened wheel rolls. - Old ConRail Engineer
I’m not so sure they were using “FLAT TIRE” in that context. They were referring to the angle of the wheel as it gets FLATTENED from use /wear. All train TIRES ( they call them that ) and like a cone. This centers the wheels / axle assembly on the rails and keeps the flanges off of the inside of the rail. In conjunction with the shape of a proper tire face… is the Rail itself as it is angled slightly to the center of the track gauge
@@francisschweitzer8431 I was also led to believe the `tyres` had a cone shape to allow for the slightly different rotational speed on a set of wheels as it goes round a bend and the `screeching noise` due to the wheels sliding slightly in one direction to compensate.
The use of “emergency” tire change in this video is overblown. Except for a rare tire blown on landing or perhaps a rejected take off, wheel and tire assembly replacement is very routine maybe maintenance. The in fact, the vast majority of tires on large aircraft are replaced at well before reaching any any safety limitations to facilitate recapping them.

They also ignored the fact the tires and wheels were only ground flat in one area, meaning they were not rotating.
@@robertheinkel6225 So, did they have the PROOF shoved down their throat? A flat spot on all 8 tires is a huge indicator of what the real issue was!!!!
I find there is a constant mix up between the concepts "tire" and "wheel". A tire as what you mount on a (tire)rim, and at that point you have a wheel. Note that at some time during the train section (ca. 6:55 and 8:00), the word "tire" is used.
Yes this bothered me to no end. Though technically the wheel (rim) is considered a wheel regardless of whether it has a tire installed. I laughed when she said the C-17 tires were $40k ea. You could outfit the whole C-17 for $40k lol. The wheels might be ~40k ea, but even that seems high
@@597ryan6 I'm an old fart - a 'wheel' has a 'rim' meaning the lip around the edge. Like the 'rim of a glass'. When I hear people say something like 'those are nice rims' my first thought is 'what, you don't like the rest of the wheel?'. Somehow today "rim" has become interchangeable with "wheel". But hey, it that's the biggest thing I have to complain about in the world that's no so bad.
In the language of technical documentation, they're replacing the "tire/wheel assembly". The tire is mounted on a "wheel assembly". That's because aircraft use 2-piece wheels or "split rims". The wheel assembly consists of a number of parts, including two wheel halves, an o-ring to seal the halves, and a number of tie bolts, washers and nuts.
@@donhappel9566 You're not an old enough fart. Look at a Model T: the wheel is similar to a bicycle, it has separate hub, spokes, and a rim. Structural wire wheels were common through the 60's, and are found on motorcycles and bicycles today.
Had a roll by with a coal train and told the crew to stop and check it out…they did not due to green lights for home…in conclusion a foot long section of the train had broke off and every rotation of the wheel cracked the rail. Crew was fired and millions in repairs to the rail. Old rear brakemen report (78/79 era)
Flange squeal and flat spots are two different things..... You'd be surprised just how big a flat spot can be before it gets changed out. Changing wheels cost money in time, manpower and equipment. It's even more so on a Locomotive (traction motors are another animal).. Flat spots on cars, are usually precipitated by not releasing the handbrake and dragging the car for a distance. A flat spot on a loaded Coal car is like running a jackhammer on the rail..... You'll know it when you hear it, and it isn't good for the rail.
3:00 That wheel brake system is built like a top fuel dragster clutch. There are plates splined to the wheel, and sets of discs and the piston caliper slows down the wheel. Most powerful brake I've ever seen.
This is why hydraulic failure in the landing gear is so bad. The aircraft brakes function like truck breaks where you need hydraulic power to *stop* breaking. If the tires don't move, then the plane spins out. And the landing gear isn't designed to take many tens of tons of force *sideways*. This is the cause of the cargo plane crash that happened in colombia.
Those brake disc float inside the wheel hub, when hydraulic pressure is applied all the disc squeeze together. Most brakes on aircraft are made of a new composite compound that never heats up when applied.
@@patrickskelly7520 that is what I said. Nearly identical function as a dragster clutch. Dragster clutches are steel, and they do weld themselves together.
@@patrickskelly7520 Oh, Patrick, I wish such a magic compound existed. Basic physics: Any vehicle braking system system slows the vehicle by converting part of its momentum to another form of energy. With hybrid or all-electric cars, some of the energy is used to turn generators to convert momentum to electrical power for charging batteries. Airplanes do not have such generators. On ANY friction brake, no matter what the material used in its construction, the energy is converted to heat, either directly through heating of brake components or indirectly by heating a cooling medium. Pilots have access to apps in the performance computer to tell them how many pounds-foot of energy was generated during an emergency stop from a particular ground speed at a particular weight, so they generally know what is going to happen before it happens: braked wheels may require a long cooling time before the airplane can be dispatched, or the thermal fuse plugs in the wheels are going to melt very soon and flatten the tires, or the crew needs to call for immediate assistance from the crash trucks to mitigate the damage as the brakes begin to melt down. Composite brakes are lighter and can withstand higher temperatures than metal, but the exact same heat is generated by braking with any friction brake.
It’s better to keep the parking brake set until we install the wheel it will avoid the brake disks to move and keep them align to facilitate the wheel to slide easily through the brake disks until the last one then we can release the parking brake to spin the wheel before final torque Thanks Aircraft engineer
Aircraft tires are to be changed when they are worn, cut or pressure in the tire which if it is low enough might require the other tire on the same axle to be replaced and has nothing to do with time or landings. Also, emergency or not, the process is the same. Half the video is about train wheels and I'm sure there is a lot of wrong info with that.
I'm pretty sure the video being shown at 6:08 is from the 2013 Metro-North accident in the Bronx that was determined to be due to excessive speed brought on by the engineer having a sleep disorder and nothing at all to do with flat spots on the wheels.
The big aircraft tire replacement caught my eye, but I like trains as well, and was very much interested in the segment on trains. It takes a lot, to keep up with the preventive maintenance, on both the trains & the planes.
Congratulations, Earl, on using the word "preventive" correctly. It seems that half the world does not know that there is no such word as "preventative."
As an AMT of 38 years I've never heard of any aircraft that use solid tires commercial or military! Also I have never heard of any kind of a tire "repair" if a tire doesn't meet serviceable conditions it gets changed not repaired!!! Also never heard of the 120 landing's rule?¿ As far as I know a tire can remain installed on the a/c untill it is " worn to limits" or it has damage of some sort. Most tire wear is caused by pilots over breaking and taxing too fast and cornering too tight! Not the actual touch down. Also the tire n wheel assembly is attached to the Axel not the Strut as stated in the video. And the Axel is attached to the Bogie beam or truck and that is attached to the strut.
One of the reasons I became flight crew in the USAF after being in aircraft maintenance was because I got really tired of someone bringing me something broke to fix. I much preferred being an operator over a mechanic, but I get it some people like the mechanical aspect.
what is 'hypnotic' about aircraft tire repair... i don't even remember seeing any aircraft tire repairs in the video... and although interesting, what's with train wheels..?
Agreed. They should be a little more careful with their definitions of a flat spot. At least two definitions: 1) the train wheel looses its conical shape and thus becomes flat, 2) a section of the wheel goes flat because the wheel brake prevented the wheel from turning and the spot contacting the rail was ground down. Subsequent use of the wheel causes a thumping sound when the flat spot comes in contact with the rail head.
Thank you for sharing this informative video and most importantly, you used a professional voiceover lady instead of the crappy robot voices used by so many others in their videos. It was a pleasure to listen to her speak.👍👍😀😀🇦🇺🇦🇺
Rubber tires on train wheels? Rare. Mainly used on relatively light load passenger trains/streetcars. IF you design with only one axle at each end of a rail car you can significantly reduce the adverse loads on the wheels, but you end up with at least twice as many railcars to carry the same load.
Germany tried that on their first high speed trains, the rubber could deteriorate, then the metal tire would shatter, one came up through the floor and would have the passengers, the seat was empty.
I am fairly certain that tires are not „repaired“. They get swapped out, period. It’s not like you can pop a can of fix-a-flat in there or slap on some flex-seal and call it a day. If anything, the tires might get sent back to the manufacturer who carefully checks and re-treads the tires if they are still viable. (Maybe there are mechanics around here in Comment-Land who can chime in here as I am out of my depth on this topic).
Aircraft tires are re-treaded around 10 times during their life. The tire life is tracked and tires exposed to high heat locations have shorter lives while tires in colder climates get more life extensions through re-treading. The carcass of a commercial aircraft tire has 14 belts for strength and to serve as a wear indicator. When a belt is showing, it is time for a retread. Some tires have the most critical inner belts colored red. Any exposure of red belts ends the tire's life.
This video only shows "CHANGING" aircraft tires, no repairs, and then the rest is about railroad wheels. Who titled this bogus video?
TV

At least two definitions: 1) the train wheel looses its conical shape and thus becomes flat, 2) a section of the wheel goes flat because the wheel brake prevented the wheel from turning and the spot contacting the rail was ground down. Subsequent use of the wheel causes a thumping sound when the flat spot comes in contact with the rail head.
why did this go from dealing with aircraft tires too train wheels??
LOL. That's the same thing I was thinking too.
Hi Airforce Team
Plz fit Front side Extra Tyre section
Meens front side only 2 tyres is there only Extra 4 weels is safe lading 100% 👌👍
Thank you for sharing this informative video and most importantly, you used a professional voiceover lady instead of the crappy robot voices used by so many others in their videos. It was a pleasure to listen to her speak.👍👍😀😀🇦🇺🇦🇺
Just a random collection of plane and train video, maybe 30seconds of changing a tire on a plane
Interesting, if not a bit meandering
Rubber tires on train wheels? Rare. Mainly used on relatively light load passenger trains/streetcars. IF you design with only one axle at each end of a rail car you can significantly reduce the adverse loads on the wheels, but you end up with at least twice as many railcars to carry the same load.
Germany tried that on their first high speed trains, the rubber could deteriorate, then the metal tire would shatter, one came up through the floor and would have the passengers, the seat was empty.
....... good thing that rail grinding train carries 500 gallons of water!!! Now I can sleep at night.
@6:18 That's what the Germans learnt the hard lessons after the devastating ICE train crash in 1998 that demolished the entire road bridge in Eschede.
Aircraft tyres are reused after new tread is fitted by the manufacturer several times before it is scrapped.
I am fairly certain that tires are not „repaired“. They get swapped out, period. It’s not like you can pop a can of fix-a-flat in there or slap on some flex-seal and call it a day. If anything, the tires might get sent back to the manufacturer who carefully checks and re-treads the tires if they are still viable. (Maybe there are mechanics around here in Comment-Land who can chime in here as I am out of my depth on this topic).
Aircraft tires are re-treaded around 10 times during their life. The tire life is tracked and tires exposed to high heat locations have shorter lives while tires in colder climates get more life extensions through re-treading. The carcass of a commercial aircraft tire has 14 belts for strength and to serve as a wear indicator. When a belt is showing, it is time for a retread. Some tires have the most critical inner belts colored red. Any exposure of red belts ends the tire's life.
Got planes, trains....
Where the hell are the automobiles?
Dropped a B52 tire/wheel assy and it dented the concrete as in not a crack, a 3/4 in impression.
Ooo nooo
Nice❤❤ sharing my friend iam new friend
What do train wheels have to do with aircraft tires that was dumb
Interesting
The leap from aircraft to trains was a bit much. They should have been separated but interesting none the less.
I'm too drink for this video right now
I was waiting for the hypnotic effect of an aircraft tyre change… I blinked and suddenly it was about trains? 💁🏻

How about spinning the tires up to speed by some means before contact with the runway?

Aircraft Tire Repair! I didn't know aircraft fly on rails.
Cadê as aeronáveis de outros fabricantes?
