Too much stretch and flex outside of the tire, put it back in and it will be fine.
I live in Las Vegas and thorns are a real problem. I averaged at least one flat tire per week. Then, I got five in one week. I had enough and decided to try two Slime tubes pre-filled with Slime. I didn't get a flat for 11 weeks! That was a record. When I finally did catch a thorn I could see I had lost some air, found a thorn sticking in the tire, pulled it out, heard a hissing noise and then it got a little wet as the Slime did it's thing. It was low but still had enough air to get me home. I filled it up and that was five days ago and I'm still riding. I guess you could say I'm sold.
You just sold me.i just bought a ebike and was 15 miles away from home and Yup got a flat. I guess I just buy 2 slime tubes and hopefully I'll have the same outcome.. Thanks 👍
@@scottchubb3718How did the slime tubes perform on the ebike?
I can tell you from experience that it does work. I was running sealant in my inner tubes on my Journeyman. Never even knew that I had punctured my tires until it came time to switch to my winter tires. I took the tire off the rims and the inner tubes on both tires were completely shredded. It was a headache trying to peel the inner tube from the inside of the tire because they had become stuck to each other. However, I rode 2,000 miles on them with no flats. Zero loss of tire pressure.
what brand sealant and type
Yep. Sealant in tubes works great. Only problem is snakebites. So since you have to avoid those, you can't go lower pressure and risk it. Have to ride higher pressure.
@@ZenEnduranceu doing Mountainbiking on those buddy??
amazing. I've been putting sealant in my tube as well a little over a year. The best decision I ever made. you know it works when the tire changing time comes. You see dried and liquid sealant in the tire and no loss of pressure. God is good!
I've been running sealant in tubes for a while because my OCD won't allow the chance of mess that can go along with tubeless setups. Plus, if you've ever seen what can come out of an old tubeless tyre, putting that stuff into a tube just makes sense.
V Garner I've run tubeless on over 20 k of gravel with no issues. Twice a season add sealant. 3 bikes, 4'years , no flats . And improved ride. Never had much of a mess. First seal a bit seeps while the tires takes its shape. Wipe it off and go., best improvement in 5'decades of riding
Been doing this for years after a massive thorn experience on a tour. I never seem to get flats anymore! Sometimes they get low but i just pump'em back up. When changing my tires for winter, i notice all the places the tube is stuck to the tire which would have needed flat repair otherwise.
I have been running sealant in innertubes for a while. In my experience it doesn't help me if I get a pinch flat. But it takes care of all the other little punctures that I seem to get (thorns, glass, thumbtack, staples, little shards of wire from car tires). By the times I get something big enough that I have to pull the tube and swap a new one in on a ride, I usually find that I have to pull out several thing from the tire so I won't puncture the new tube.
I’m from Arizona and I either run with sealant or I walk.
Seriously
So many thorns in AZ, you'll catch a flat before you even leave the house!
Those darn goatheads....tiny spiky doom stars
When you removed the tube and added air and added air again later, the hole was stretched and it needed to be sealed again, that is why the sealant leaked each time. The tire carcass keeps the tube from stretching more. Also, inner tubes are made from butyl rubber which has no rebound like natural rubber or SBR, so running tubeless will give better riding. (Make a slingshot with an inner tube and with a piece of surgical tubing to see the difference. Each flex of the tube going around the wheel is like pulling on a slingshot, the other rubbers bounce back while the butyl rubber is like a shock absorber.)
So which one makes you go faster on farmland and can a tubeless get punctures to the point you can’t ride?
I can't make a slingshot with a tubeless tire, where's the rebound ?
@@gamingofthelegend3907 tubeless will suffer flats .... Airless will not
Wow. A very good explanation to explain the “performance factor” of tubeless tires
It's a fun look into your life behind the camera when you include the thumbnail capture and go, "ohh youtube" ha
Russ, I love these kind of experiments you're doing there, even if something like that doesn't work out. Always inspiring seeing you breaking the rules.
My brief experiment with pre-filled slime tube came to an end when I got a snake-bite puncture on the ...er..inner part of the tube i.e. where the tube meets the rim. centrifugal force means the sealant only covers the outer part of the inside surface. When I took out the tube and tried to manipulate it I ended up with a messy tube that patches wouldn't stick to .. and then I walked home because I forgot a spare tube...
Some years ago I decided to give this a try on my skinny tire commuter bike. I took the tubes out and disassembled the valves then poured in about an ounce of sealant in each tire then reassembled the valves and put the tires back together again. I then rode that bike for two or three years until I eventually got a large gash that allowed the tube to poke out from the tire and it rubbed through. I couldn't see the gash because of my full length fenders so I was not able to replace the worn tire in time to save the tube. I replaced both the tire and tube without the sealant and since have gotten about three flats so far. The last time I got a flat I replaced the tube and put an ounce of sealant in it and have not had any issues nor flats since. One thing to note is that my tires seem to hold the air better with the sealant in them where without the sealant I would need to pump air into the tires once every two or three weeks to not needing to pump more than a few PSI every few months.
Tubeless works best for fat mountain bike tires running low pressures for better traction since low pressures on a tubed tire can lead to pinch flats.
Wow Pete that was a ton of info I am gonna try to remember all that when I am on the trails in Montana
After my last flat, I put sealant in all my tubes and then carry a patch kit just for back up or large holes. So far hundreds of miles with no issues/ flats.
I used to run the original "Slime" in all my tubes before tubeless came around, worked like a charm but that stuff is so thick and heavy for the first 5 mins of a ride on a cold day you could really feel an imbalance in the wheels until the thick goop had spread itself around the tube. Getting it into a presta valve tube was always a hassle too.
Yep Slime. Im in Phoenix AZ. In the Summer heat,slime forms into balls or marbles. You can hear them rolling around! And they do not melt back down. It's 111f today.
I still have slime in tires. Definitely not as good as stans but does work
I understand that the Slime can cause corrosion on metal parts.
I stopped to help a guy with a flat. I was going to patch as he was 26" and I was 700c. I took the tire off and that slime crap was EVERYWHERE. I couldn't help him. What a mess. If I'd ever considered using it I was over it after that.
@@freedomwon2004 I never had that problem, 111f ain't something we have to worry about in the UK (yet), but I can imagine it, seeing as how that stuff sets.
Was doing this with slime tubes 20 yrs ago, works great! Slime had high fiber content, and the green slime made punctures visible on the tread, no guess-work. When I run.out of my stans I'm going to try slime again.
4:17 My guess is that when thorn or something punctures the inner tube with its tire sealant, I mean by science that sharp object also acts like a seal around the sim or seem while the air is pushing the tire sealant into that sim creating double sealing effect.
I put sealant on the tubes and just finished touring from Tijuana to Can Cun. 6000 kilómetros with CERO flats. It works believe me.
I just tried this today. It worked well. It was only a temporary fix since I have a tubeless tire I plan on switching to eventually
If nothing else, a little sealant is insurance and may give you just enough of a boost to get back home/ to the car so you can change the tube out in comfort and not on the side of the road/trail. Nice!
Use stans in the tubes for two years. Works great. Normal pump and patch if needed. But i have not had a flat yet.
I've had good success with sealant in tubes plugging all the little pin-pricks you get here in S. Arizona. But when you get a big thorn or other large puncture, I've found you can't really use bacon strips to pug the hole, and so you still have to pull the tube & patch it. Decent trade-off, for the usual little punctures, though, especially when you're running older rims that take a lot more work to make tubeless-ready.
I bought a tube that came pre-filled with a green sealant (Slime?). It seemed to hold up to mountain biking in Sedona and all those cactus thorns. But these days, I would just go tubeless. Especially now that we have tire plugs.
Half my bikes are tubeless. The other half I've wondered about this. I knew if I waited long enough someone would do it. Hahaha Thanks atb, Tony
I used orange seal in a literal combat zone, between shrapnel in the sand and goat heads I was flatting out twice a week. Got some Orange seal in the mail and added it to the tubes, got several orange streamers (sealant coming out) but no flats over the next 9 months.
I tried this experiment sort of by accident and poured a full 2oz bottle of Stans-NoTubes into a hybrid tire tube (without removing the tube from the tire) and filled it to 60psi. prior to adding the sealant, the tube was completely flat even after a Bike Tech had inspected it the day before and said it was good to go, but went flat overnight. did not spend much time spinning the tire around to spread the sealant and it has been sitting idle for a few days now and it’s still rock hard…
i used to put sealant in the inner tube of my tubeless ready mtb. i had a pinch flat in spite of the sealant. more importantly, i could not patch the tube. the sealant leaking in the area did not let the glue and patch stick. i converted it to tubeless after that. no problems with cactus spines and had to put in bacon strips once 2 years ago for a larger sidewall laceration that wasnt sealing on it's own and that fixed that. I'm still using that tire 2 yrs kater with the bacon strip still in place.
I use Kenda tubes with sealant at 100 psi on my road bike. It got me out of a jam. Returned home after a 50 km ride and discovered I punctured. It never flatted and I was none the wiser. In the end, I had to replace the tube because sealant kept oozing out. It will get you home.
during the late 90s I put a "car sealant" in my inner tubes, the car sealant was so thick that I did not have a puncture for many months , so by the time my John Tomac tires was so worn out the inner tube holes glue itself to the tire wall, I did the same using bike and motor cycle sealant but it did not work at all.
i experimented with sealant in tubes in a pair of gravel tyres. ran them for half a year and totally forgot about the sealant. when i swopped them back to commuter tyres, i was surprised to find the rear tube covered with dried sealant, so it did seal a puncture that i had hitherto been unaware of. because the sealant had smear and dried all around the tube, i'm not even sure where the puncture is!
I started putting Stan sealant into my tubes and installed the tube into the tire, which still has a lot of life when I could seat my tubeless tire anymore.
btw, do you need to refresh stan sealant inside tube like you would if you were running tubeless like every 4-6 months? Does sealant dry inside the tube?
i wonder how much you need. This is good to know. In DK I expect to run tubeless, but if a problem exists insert a tube. So if another problem exists, you could put sealant in the tube too, if you have enough. I would be willing to try this out if nothing else is working, in order to keep pedalling. thx.
While a tubeless set up may avoid snakebite punctures, when running low pressure you still run the risk of burping air and flatting.
I used to do this on my road bike, and it totally does work, but with some caveats of course. The sealant does seize up the valve cores after a while, and eventually you will get a hole it can't seal, and then find yourself riding home with a horrible sticky mess of sealant-covered inner tube in your jersey pocket. My ghetto setup failed finally when it punctured in the rain and couldn't seal.
These days for road riding, I went from Conti GP 4000's with the inner tube sealant hack to slightly heavier duty Conti Grandprix GT's with puncture protection strips added between the tube and tyre, and 1,500Km later still haven't had a flat. Feels much the same, but won't have to faff around with sealant when it inevitably does puncture.
So for me, I'd either go tubes without sealant for road, or fully tubeless for MTB/gravel, but the inner tube sealant hack totally does work and is worth a try. Assuming you have tubes with removable valve cores of course :)
I don't know about the kind of sealant you're suing here, but I have found on the tubes where I've used Slime or Fix-a-Flat sealant, the valve eventually fails to hold air. A little bit of the sealant ends up fouling the seal at the valve, and I end up replacing the tube. However, the sealant has gotten me out of a few jams, and I would have replaced the patched tubes eventually if I had patched them instead. No real loss.
I use to use Slime in my Mtn bike tubes back in the 90's, worked most of the time. Nowadays my new Trek Roscoe 8 is setup tubeless and it has already proven to work. One of my local trail networks has alot of thorns and I have found several stuck in my tires upon cleaning my bike.
Flat out works really well in a tube, it has Kevlar fibers
In my experience stans Sealant in tubes works sometimes and othertimes not so much. Good to have options in case it fails. Ie still carry a spare tube and patch kit.
I developed tyre sealants 30 years ago before the tubeless systems was there.I have 17 brands over the world ,same s!t different labels. I push the nozzle directly through the tube a drop of superglue and a small piece of tissue paper on the glue...works perfectly.
keep in mind. like you said, the tube will be inside the tire. you have the pressure against tire and the fact the tube isnt expanding... the holes when inflated outside of the tire are SIGNIFICANTLY more free to open up and allow air out without resistance. I put STANS in ALL my tubes now. NEVER have flats
I've always ran sealant in my tubes. Maybe that's why I never understood why people hate inner tubes so much!
The problem with sealant in tubes seems to be that the valves clog, at least on the Slime brand self sealing tubes that I have used.
You can take the valve cores out and clean it all up
I helped a guy with a flat and his valve was stuck open due to so much dried slime in it. I would not bother with sealant in an inner tube.
@DFW rider Yeah, that happened to mine too, they were bulging. I remember winding fishing line around one once because I was worried it would burst and I couldn't replace it right away.
When I install Slime, I must put a dab of oil on the valve stem threads or it will be a bear to untwist later.
@@tjrioux3059 Silicon grease on the valve thread is what you want 👍
Doesn't affect rubber.
The benefit of sealant in a tube is to buy you time. Usually you'll get a slow leak that could be repaired or replaced at a more convenient or safer time and place.
Great video man
Coagulating is the correct term but I like the other one better. "Bugger up", definitely more fitting and visceral.
Awesome video
Yes indeed. I use orange sealant in 3 bikes in tubes. Works as well as tubeless and the sealant doesnt dry up near as quick in a tube...Ive actually never had a flat running sealant in a tube. Centrifugal force plays a roll in sealant doing it's job. And yeah tubes are inside a tire usually.
Orange seal is the best ! Have never put it in tubes though
I have three bikes. A Specialized Rock Hopper hard tail, a Salsa Mukluk, and a Specialized 2018 AWOL. The Rock Hopper is tubeless. It's great. But at too low of pressure I burped it once and lost a lot of sealant. (I learned not go too low!) But the Mukluk I've never done away with the tube. (Lazy maybe?) I've had probably thousands of tiny punctures, but so far nothing horrible. It does make for a heavier ride though. And currently I'm still running tubes in my AWOL (with Orange Seal). So far, even on chunky gravel, I haven't had a problem with pinch flats (yet). But, I'm soon going to upgrade to 42 mm, instead of the 38's I'm running now, so I may go tubeless then. Not sure. I was glad that you had luck with the inner tube sealing up. I will say that if you get too many tiny punctures with sealant in the tubes, that it will eventually migrate between the tube and the tire casing, and it can be a mess when you do take the tube out. But it's not been a huge issue for me. Thanks for this look at the tubes and sealant issue. I've been doing that for a long time.
I tried to convert to tubeless my (tubeless wheel + non-tubeless tire) and i did seal the system,
but yesterday it popped off, so now, i injected tubeless sealant in each inner tube, and tried to cause some punctures and it sealed just fine,
I don't know how will it work overtime but for now works exactly as tubeless setup, minus the messy caused by the sealant inside the tire... worrying about the tape sealing perfectly, tubeless ready tires price... we shall see
Yep, kinda works for tiny pin pricks while the tube is supported by the tyre. It will significantly slow thorn punctures. Fundamentally though, the tube is too stretchy. Air pressure can force the sealant grit through even a tiny hole in a tube.
With a tyre, the webbing that stops the rubber from ballooning under pressure also stops pinholes expanding much beyond the size of the thread pitch. If you slash the tyre, the sealant can't work because it just gets pushed through. Even repair noodles are only good up to a certain size of hole.
You can patch a slashed tubeless tyre but if the parches are rubber only (no webbing) you also need to stitch the gash together first. Otherwise, the patch with prolapse out of the cut.
hi can you use inner tube sealant on a tubeless wheels? i bought a muc off inner tube sealant instead of a tubeless sealant, i wonder i can still use them for my tubeless wheelset
Slime makes sealant specifically made for tubes! Ask me how I know??
I put sealant in a tube with a pinhole In it . The tube not installed in the tire . It sealed the hole . days now . So I put it in the front and rear tubes .
4 days ,30 miles ago .
And counting .
Using sealant in my tube since 2013. The stuff is different than the one I'm using in my MTB tubeless setup! You need tube specific sealant in this case.
I use car sealant .
It pumps the tyre and seals.
Given the opportunity, replace the tube when you get a leak. Even old fashioned patching isn't a sure thing. And the 'new' self-adhesive patches? Every one I've ever tried has failed, albeit not immediately. If you do patch a tube, use the 'old' style of doing it, but take time to do it right.
If you're caught in a rain storm or losing light, then the sealant can be used as an emergency back-up. Otherwise, replace the tube with a new spare, or one that has been patched prior under the best of circumstances, and left inflated for weeks to prove the viability of the patch. Something I've learned by cycling for over half a century is to buy quality adhesive and patches, and the smaller and thinner quality patches are almost always best, as they stretch with the tube, not leaving thumping flat spots.
I'm a fan of those little self adhesive patches. They have been good to me.
For me, the adhesives worked without failure ever since I tried them. I applied at least 10 for sure, from different brands too (lezyne, park tool, topeak). The circular shaped patches are superior among these.
Maybe you had bad luck? I wouldn't dismiss them yet.
We have tried Park, Topeak (which are both clear square stickers) and Scabs (can't remember the brand of those) which are round black foamy stickers. Park have been the best but none of these last forever and if you read the small print it says they should be considered temporary. Still get 6 months or so (maybe more) out of them by which time I'll have at least 5 repairs and decide it's time for a new tube anyway. The scabs drop off after a fairly short time so I avoid those.
Agree none last as long as a properly applied glue type but they are quicker and cleaner. Generally if something can get in my eye it will (seriously - 5 trips to eye casualty so far!) so personally I avoid the glue versions on a trail as it might take me a while to get my eye looked at when I squirt glue in it in the middle of a forset.
I’ve been using “Slime” since I was a kid in my mountain bikes! I’ve heard the rhetoric many times about Slime attacking valves etc. because it’s a petroleum product but I’ve a problem!!!
I’ve had great results with *Southwest Sealant” but it’s been discontinued!
If you wanna run tubeless run tubeless with your favorite sealant but DON’T put tubeless sealants in your tubes!
Run Slime
After a few goathead thorn flats, I tried sealant in the tube on some of our bikes a few years ago. (I was using Orange sealant also.) A few months later, I had multiple failures where the tube blew out at the valve stem. The tube blew open so far it could not be patched. There is some internet chatter that the sealant "eats" away at the glued joints at the tube's valve stem. Not sure if that is true, but I gave up on sealant in tubes after several nasty failures. I now run tubes or conventional tubeless.
In japan people with those commuter bikes use slime sealant in their inner tubes. It does work.
By far the sealant I've had the best luck with is Bontrager. I use it in TLR and inner tube set-ups and it works great.
Looking forward to the update video. I was interested in the Muc-off inner tube sealant but if this works it's probably a cheaper alternative.
Hi, anyone tell me, i have normal road bike and i don't have tubeless tyres so i want puncher sealant in my inner tube, so is that possible so use puncher sealant in inner tube and how can we use? And how we put the sealant in inner tube?
It's basically the same idea as Pannenschutzspray. People will have a canister of this stuff in case they get a flat on their Holland style bike. It's basically compressed gas and sealant in one "shot."
I use it in the tube on tours. It has worked for me when I hit many goatheads thorns, for miles and no amount of patches would.
However it doesn't mix with patches, because it eats the patch and leaks again, in a short time.
Recently found your channel and enjoy the content!! Although, I would appreciate a video about drop bar shifters and comparability. I am working on converting my old Trek 8700 Pro Composit into a drop bar gravel bike. Cheers!!
Ok, that's a cool experiment but I'm wondering how will it perform when a thorn goes thru the tyre and stays in? Will the sealant be able to cope? I think that's what usually happens once u ride over sth sharp - it tends to stay in the tyre constantly going thru the tube.
If seal not working should i repairs in the workshop?but you know if you wanna repairs in the work shop you should make a hole for coating. Is that good same like another inner tube without sealant inside?
Should probably be running some higher pressure then that with tubes, 40-60 is as low as I would go weighing 150 pounds. Haven't had snake bite in years.
That would be WAY to high for 650b x 48s.
I'm 200 lbs
The low pressures skinny guys talk about running are ridiculous for riders of my size.
@@PathLessPedaledTV Works fine in my 27.5x2.2 mtn bike tires.
Jonathan Benn I’m 192 and i run 35 in the front 45 in the rear on 700c x40 tubeless. For mixed riding
@@PathLessPedaledTV Snake bite only occurs when tire pressure is to low or you case a jump, I don't think you took that cool alt bar bike off any sick jumps, so I'm gonna go with tire way to low.
I only ride tubes, I only ride my mtn 100 ish miles a year, so sealant isn't worth it to me.
I'm in the excluded bunch that likes to go fast so I usually ride a road bike, but I'm getting the vibe I'm not even welcome to watch anymore.
Abiut your community post the other day, you are the definition of hipster, forgot about your Brompton days? That was less then a decade ago....
You also posted review's a year ago when you still wore lycra.
How long did the orange seal stay flowing adequately inside the tube before thickening and hardening? Once coagulated inside the tube, do you have to throw the tube away?
I might have to try this out. I could never get ghetto tubeless to work, thanks!
I’ve been doing this for years and it has always worked great.
how often do you change the inner tube? regards
Santi del Estero around 4-6 momths
I've been putting slime style sealant in my road bike tires for years. The hikes that I put it in never received punctures ever again. So I put in all my tubes. Literally I've got a bile that has had sealant in since 2016 it's now 2022 and still never went down. I ride 23c tyres over bumpy trails and then jump back on the road. Bump up and down curbs with a little bit of care but without sealant would have got flats lol been out on rides with friends and they have had to stop because of flats and I've never had one in any of my bikes since putting sealant in
.. I've never changed tyres and inners so wouldn't know what they look like on the inside but in my opinion it definitely works. Never had an issue with valve clogging up but I always blow down them after putting sealant and make sure that no other air gets down them while putting the valves back in. Apparently sealant isn't toxic and if I ever got a taste of it I spit it out before swaloing it lol.
I've never had the chance to buy new tires.
Today I got a piece of shrapnel in my tire it was still at full pressure and showd the guys in the shop and they never seen anything like it. I always pour twice the amount they state on the sealant. It makes your tire a little heavy but I don't care if I never have to change a tube by the road in the cold.
Today I pumped up the tire in an old bike I haven't used for about 2 years and the sealant seemed to sit still in the tube for a while but after it got spinning it was absolutely fine. They say it lasts two years but I've got a tire that has all tred gone down to beading and still never had a puncture lol.
Fill up the tube, put it in the tire and job done
You might as well just ride a solid tire.
@@PathLessPedaledTV its not that bad lol they say use half a bottle for bikes but I can't judge a quarter bottle so its easier to use half lol 😉 ... I nearly bought solid tyres but apparently they don't handle well. Have you ever tried one? Half a bottle is barely anything lol
what's the point to test sealing tubes when they aren't inside the tire?
??? I dunno to show you on video because I don't have a magical microscopic camera to put in a tire.
I’ve run sealant in my tubes a couple of times, and they worked pretty well when I picked up small holes. Biggest issue was gumming up the presta valve.
Do you think that could be prevented by making sure you keep the valve pointing up when parked/stored? So any sealant in the valve drips back into the tube?
@@Dominik-vn6lo I'm thinking maybe grease the inside of the valve and core with a pipecleaner to try stop it sticking
I look at this method as having run flats on a car. It’s not the end all be all solution but will get you home where you can then replace the tube with a new one if you don’t carry one on you.
I have used orange endurance in three bikes with tubes, and it works quite well. I wore out a gravel king tire, and when I changed it, found a wire in the tire but never lost air in the tube.
I've used sealant inside inner tubes for years and I can confirm it definitely works. But the inner needs to be in the tyre to stop the hole stretching. But it's sealed loads of punctures on my bikes and is easier to use if taking your bike on a plane.
I did the opposite and went from Orange Seal back to Stan's because Orange seal evaporates way too quickly at least down here in the Florida heat.
I switched from Stans to Orange and noticed the Orange dries up pretty fast but the Stans would always start bleeding through the rear tire after 500 miles or so.
Just use the Orange Seal Endurance formula.
@@watertankhikes It's not much better.
Sealant in tubes will definitely take care of slow leaks and pinholes, but in gravel or road tires, it has the same problems as road tubeless: the pressures are just too high. That's why tubeless is the norm for MTB, but tubeless is still hit-and-miss for roadies... 80-100psi just blows the sealant through anything bigger than a pinhole.
So it seems like sealant in inner tubes gives you a bit of puncture protection, but doesn't give you the ability to run low pressures like a full tubeless setup would. I guess it's a decent tradeoff for someone who hates seating tubeless tires.
I know this was posted three years ago, but does anyone know what type of air pressure gauge he was using? He said it was the Rolls-Royce of pressure gauges but never said the brand name of the gauge.

@@PathLessPedaledTV Thank you Thank you sir!!
I use slime car stuff when I have very little time to patch up my commuter. It works for a few days, then it unseals if the tires aren't rolling. This solution is pretty great if you were gonna change the tube anyway, because it's thicker than bike tubeless sealant, so it seals up quicker and doesn't spray everywhere (+you can get it in hardware stores or even big supermarkets). Doesn't work well with patches though
the stuff leaks, when you ride it and it also can freze and when that happens it tears your tube.
How about these on a 2.6 wide tire with a tube?
I've been running Muc-Off sealant in my two bikes with knobbies. I just yesterday hit a decently large chunk of glass in the front tire of one of my bikes, resulting in a hissing puncture. I popped out the glass with a guy and it kind of settled out, and then went home to patch it. While checking my tire for anything else I found a thorn and a piece of wire, both of which has already punched through and not resulted in a flat. I think of the glass had been smaller and less of a small slash in the tube I wouldn't have found myself patching it.
I ran an inflated and patched tube through a bucket of water and couldn't find the other punctures, so I am concluding they sealed so well I don't need to patch them.
I'm impressed.
May want to mention that not all Presta valves have removable inner cores. It’s good to check this when buying tubes if sealant is to be used. Cheers
Hello, your mistake was to use Stan's no tubes sealant, I think there are better sealants and it would have been better to use a Foss brand tube that works much better. Greetings from Colombia 🇨🇴 👍🏻 😃
I've heard that the sealant works best as you ride or spin the tire because the centrifugal force forces the sealant outward into the puncture.
It does. My 16" tubes were leaking through the valve cores. Splooshed in 10 oz each of Stan's and the problem went away. It does help that the tyres are Marathons.
BTW, what's the Rolex of bike tyre gauges again?
I thought about going tubeless mainly because I have arthritis in my hands and can't always get the tire back on the rim. However, my lbs suggested I try sealant in tubes and so far so good. I had flat on my hardtail that sealed fine after I pumped it up and haven't yet had a puncture on the gravel bike as far as I can tell.
You have to give it time. Move the puncture to 6 o'clock. If sealant can stop punctures on tires, why wouldn't it seal a tube? Answer? It does. I speak from experience. Aloha. 🤙
I had a flat due to a nail on the road; I actually put some sealant in the inner tube after that, rode a bit and its actually fixed now. It does need a bit of riding with the sealant, the first two days it just lost air completely but I didnt ride with it. The third day i decided to ride with it regardless and then it holds it air really good. Used a regular sealant, not a specified inner tube sealant.
It definitely fixes most sidewall punctures.
rolex of pressure gauges...for me that doesn't sound as super accurate since rolex is far from accurate when it comes to watches :))
I've done this for years and it work perfectly
On a tube tire you hope it works. I had it work on small wire punctures picked up on the highway from worn radial truck tires. Nothing bigger. I have a high speed ebike and it throws the wheel out of balance. I replaced tube with no slime and it was fine.
I use Michelin's own sealant filled tubes, when I want to play it safe (like with commuter bikes). personal.garrettfuller.org/blog/2019/03/01/michelin-protek-max-test-the-results/
Thanks for doing this experiment. My guess is that when you shake to tube, it flexes enough to break the seal.
My guess is that the inner tube is dimensionally less rigid than any tire (it expands quite a bit when pressurized), and the sealant isn't a patch, so any changes in puncture hole size caused by, for example, pumping the tube up while it's outside the tire, or extensive flexing of tube, will cause the seal to fail. When used normally, the tube is constrained inside a rigid tire, and therefore would allow the sealant to work as if it's inside a bare TL tire.
Despite the fact that sealants should work in tubes (see: Slime and Slime tubes), you should do additional tests to verify the efficacy of non-Slime sealants in tubes. For example, install a sealant-enabled tube as per normal, and try to puncture the tire/tube with an awl, like with Stan's NoTubes demos (ua-cam.com/video/FTlZvOVG8zs/v-deo.html).
Thank you, I had no problems what so ever using sealant in a tube but leave it in the tire.
Guy at my LBS just recently was telling me he had sealant in his tubes and I was skeptical. This is poifect.
Thanks for thinking about and doing this test! Especially with a real live almost flat.... Good work!!
one would think the tire needs to be rotating as if you were riding to spread the sealant.I see many reviews with someone holding the tire
Does the sealant dries out inside the inner tube? Would I lose the tube then or can I just clean it?
Eventually would dry out and need replacement.
Orange sealant would have been awesome to
See.
