We Tried To Destroy Tubeless Tires & This Is What Happened!

Рет қаралды 94,256

Tubeless tires are designed to fix punctures on the go, by filling small holes in the tyre with a liquid sealant which then sets to plug the surface wounds. But just how good are they at preventing punctures? How big would a hole have to be for the tubeless system not to work? Can we destroy tubeless tires? There’s only one way to find out…

I’m riding 12,000 miles per year and just don’t get many flats. When the tubeless fails, you’ll need tubes or patches and you’ll ride home with a low spot unless you can reseat the tire. You’ll never get the rush of air to refill it on the road. And good luck getting the tire off. I got rid of all my tubeless wheels. Also only riding rim brakes. Discs are a pain in the neck.

I've been running tubeless tires for a while now (4-5 yrs with a total three pairs of tires). Although I did enjoy all this time with tubeless tires there is one big caveat which is seating the tires onto the wheels. Honestly, it's a mess and most times you won't manage to get the tire properly in place. Even in bike shops I've seen mechanics struggling to seat the tires. Other than that and occasionally spraying sealant to your friends it is great indeed. While riding on highways in São Paulo I once got home with three or four tiny pieces of metal that would have punctured my tires if it wasn't for the tubeless set up. So my take is, if you ride where punctures are very common I'd recommend going tubeless, if that is not the case in your area sticking to inner tubes might be easier and cheaper.

@yiannispapelis8260 Жыл бұрын

This is very timely for me, I just came back from a metric century during which my tubeless tire completely failed. These tires were somewhat old (a bit over 3000 miles on them) and the last time I inspected them I noticed they were getting soft and thin in a few places but I put them on, added sealant, and was ready to go. I definitely noticed sealant coming out of a bunch of places but it sealed and all was good. About halfway into my ride, it felt as if a spray hose had turned on under my legs, hissing and spraying orange sealant was everywhere. It turns out there was about a 1.5 inch by 1 inch portion of the tire that was popping up like a balloon! As the sealant blocked the small puncture in the middle of that section, the balloon "inflated" and the hole became larger, spraying sealant and losing air. If I tried to put my finger on the hole, the soft portion kept growing to the point it seemed as if it would literally pop like a toy balloon. No repairing that for sure. However, I did finish the ride simply by adding a tube in the tire; I kept the pressure a bit lower to ensure the tube itself would not push through the soft portion of the tire and tried very hard to avoid any gravel or other "danger" zone. The moral of the story is that indeed, as Ollie mentioned several times, you just don't even realize just how many times tubeless tires save you, and in my case, I just became compliant and kept riding with 3000+ mile tires even though after cleaning and refilling them with sealant they were oozing sealant from a bunch of places. I guess that should have been a sign!

Tubeless works really well for me and adds a level of comfort you can't get with tubes. Normally you never even notice you've had a puncture until you get home. Only ever had one puncture that I've actually noticed and that just slowly let air out over the ride although I didn't need to add any air. Only reason I noticed was the wheel jizz all over the bike and you could see it squirtting out when out of the saddle. I tyre patched that one after a few more rides. The ONLY downside of tubeless is setup because it can be really frustrating if you have a rubbish low volume pump. I have a tank and it's now so easy. Originally had pro ones and now on GP5000 TR(?) Which mounted up really easily unlike tubed GP's where you normally need thumbs of steel.

Have a "quick" fix for the glass shard issue (the very big ones never seal and plugs might won't work due to the size of the cut). Commuting in Lndn for many years, conti GP5k TL and TR in the last 3 years. Move the puncture to the top, no need to remove wheel if not in the mood... Remove shard. Deflate tyre if there is any air left. Grab your tyre leavers and open up that bit, as much as you need to access hole from the inside. Wipe it down thoroughly. Apply a park tool GP-2 "glueless" patch from the inside after a bit of sanding. Pop back tyre, inflate, and good to go. If you don't carry a CO2 inflator or a track pump, it's a good idea to do this near a bike workshop where you can use their track pump. I had to do this maneuver 3 times so far, and those patches hold. You can use classic cemented patches as well, but it takes a lot more time and they are more rigid so you really want to wait for them to properly bind, otherwise they detach in some parts and you lose pressure again. MucOff glueless patches unfortunately don't work at all in tubeless in my experience, they detach instantly, but you can use the lovely box to keep the Park Tool ones...

When it comes to plugging road tyres I found that the thicker, usually black "worms" (or using 2 thin ones at the same time) stay in place and seal better than the thinner brown ones, and the thinner ones work fine for off road pressures where the thick ones are overkill. Kind of goes against what you would expect but if you think about it it makes sense, its all about the pressure.

You can always carry tubes if you ride with tubeless tyres. The tyres are easy enough to get off the rims to fit tubes if deflated, they just push off with your thumb. I carry two tubes on my tubeless gravel bike, not needed them though, found two holes in the rear tyre that I didn't know I had, deflated to top up and noticed them as the seal broke when the pressure released. Topped up, pumped the.back up, sealed again.

I have run tubeless for seasons now and had 3 flats which were unfixable. All three were torn open side walls. 2 with Conti GP5000 S TR and 1 with Schwalbe Pro Ones. The best sealant doesn't help if the sidewalls just burst open. Will go back to inner tubes now.

A sidewall tear is pretty catastrophic with tubes as well.

@ProfGoodlife Жыл бұрын

@@andrewmcalister3462 True! However, I can just change the inner tube without much hassle, perhaps with a bar wrapper in between inner tube and tire to prevent the tubes from bulging through the tear. I could do the same with a tubeless setup, but it's a huge mess with the sealant. At this point I don't see the advantages of tubeless anymore if I still have to carry around spare inner tubes. The weight and rolling resistance thing is negligible for a recreational rider.

@@ProfGoodlife True that on the mess. I accept that risk for the benefit of fewer punctures overall, but others may make different trade-offs depending on their local conditions.

Great video! What do you carry in your pack under your seat when running a tubeless setup? For my clincher tires I used to carry co2, inner tube, and tire levers. Do you still carry inner tubes?

@heidijarvis777 Жыл бұрын

I still carry one inner tube as a safety measure plus C02 and levers but not had to use the tube

Rode across the US in 2016 on a CX bike. Mechanic friend persuaded me to run tubeless and built up the wheels using Stans i23 MTB rims… 5200km later: I wore the rear tyre out and only had one puncture on the rear that wouldn’t seal (turns out it was a cracked rim) popped a tube in and finished the trip. Front wheel had no puncture and no drama. Have run tubeless ever since

When you say tire plugs don't work, you should try the Dynaplugs. I've had bad experiences with bacon strips but the Dynaplug work really well on road bike tires (and gravel tires as well)

I went tubeless (and hookless) two weeks ago. In the week before that I had a run of 5 punctures in 4 rides! Loving the lower pressure in the tubeless setup and I’m smashing lots of my personal bests on Strava. I’ve bought a small hand pump and a dynaplug thingie and that’s all I carry on a ride now.

Some of the screws seem to have failed to penetrate the tire because they got either moved to the side or the tire went over it. They are slightly less sharp hence the zone 2 was more efficient at making the holes. Still it's also true for the real world scenario hence the test is perfectly legit. Thanks! I wonder how would be the results with a bit worn out tire.

Been riding tubeless for over a year now without issues. Until a few days ago when I crashed in a roundabout, as it turned out caused by an almost flat front tyre... It did seal itself back home when I refilled some sealant. Hard lesson learned: keep topping up that sealant regularly, running dry works only as long as you don't puncture!

I run tubeless tires on two of my four bikes (carbon road bike and e-gravel bike) and have ridden both bikes a total of 16,000km with just two flats. Both times, after taking the tire off, I realized that I had waited too long before adding more sealant, because the inside of the tires were 95% dry. Lesson learned for me-don't wait too long before topping up my tubeless tire with more sealant.

I've been running tubeless for almost two years on my road bike and have had success with the exception of 1) a small brad nail that punctured the tread and then went on the skewer the sidewall so no help there and 2) caught a horseshoe nail that went in halfway and stayed there while the sealant was spraying all over me and the frame. Overall, they are a keeper!

@adamgosztolai1502 Жыл бұрын

So the puncture seals, but will it still seal a week later? I often find that TL seals but the seal keeps braking when I inflate back to higher pressure or after some more riding. Also, fitting tolerances differ, so not all TL tires will work with your rim. Some will just slowly leak air and you’ll end up pumping your tire twice per day. I’m strongly considering going back to tubes as a result.
