We Test Tubeless Tyres To The Extreme... Can They Survive?

[@gtn]

Are you running tubeless tyres? 🛞

[@MichaelZ-1]

Nope. Not going either. BTW; there used to be city bike tires with sealant in them, wouldn’t tubes with sealant be better compared to tubeless?

[@panzerveps]

@@MichaelZ-1 No. You'd lose the benefit of reduced rolling resistance.

[@MichaelZ-1]

@@panzerveps that wasn’t the question. I couldn’t care less about that little bit of resistance in my training rides. A tube filled with that milky substance would be cleaner to install, cleaner to remove (especially when you’re on the side of the road) and to replace.

[@bucketlist.original]

No, I'm using the TPU Tubes from Schwalbe, Aerothan and am very happy with them, no puncters yet, 1000km already.

[@csobering3108]

I tried on my gravel bikes, and I have 1/2 assed it on my wife’s bike. All of my bikes are back to tubes.

[@danpiruth6385]

test results : 2 tyre changes on the tubeless (including the initial installation) versus 4 tyre changes on the tubed. If we do the math, 2 tyre changes times 10 minutes per tyre change equals 20 minutes for the tubeless versus 4 tyre changes times 3 minutes per tyre change equals 12 minutes. You convinced me to keep my tubed tyres, thank you very much !

[@DavidFritzIII]

Just out for a group ride with six friends... two of us run tubeless four of us had tubes. There was a bit of broken glass on the road and four out of four tube riders got flats, none of the tubeless... after nearly 20min faffing about, one of the tube riders burst their tube on reassembly and then about 1km down the road another got a second flat. Another 8 min on the second stop and now 30min of my ride has been spent watching a bunch of lads change their tubes...and folks say tubes are easier than tubeless 😂

[@chrisspray8010]

Then every 3-6 months remove the tubeless tyre, clean it, replace sealant - well over an hour lost.

[@chrisspray8010]

Tubeless on road bikes 32mm and under - waste of time in UK. Sealant seals for your ride but then never fully seals. Always there’s a weep of sealant as the bike sits in the garage.

[@lpeter1172]

​@chrisspray8010 maybe the sealant you use is too thin?

[@Microbit0]

Am I wrong or they have the best job in the world. They are literally playing, hammers, nails bicycles and punctures. It's like a kids dream

[@gtn]

You're not wrong! Working for GTN is amazing 🙌

[@ryuujinusa]

I've ridden over nails with tubes, had it stuck IN my tire, rode another 10k before I noticed it. But it didn't puncture the latex. I was able to use the tube for another 5000km+ km before it finally punctured. And you guys said to use latex, but you're clearly using TPU for the tests.

[@mirkocelii5543]

Yes, I looked a TPU to me too actually !

[@KB-eb4zo]

Set up my bike tubeless (same pirelli as in the test) and found that tubeless actually sucks in most cases of glass cuts, while tubes surprisingly often survive (like in the test). Since I seldomly encounter direkt nail hits but very often small glass, I went back to tubes and never regretted

[@nickc4716]

Thing is, with Latex tubes and GP5000s I’ve had one puncture in 8+ years. So for all that faff, tubeless solves a problem I don’t have. Tubeless on gravel bike though and glad of it.

[@gtn]

That's great! It's all about finding what works for you 🙌 Are you interested in the lower rolling resistance of tubeless?

[@DigininjaRobin]

I'm tubeless on all three bikes. Last time I changed the sealant one wheel refused to stay up, the shop suggested changing the tape and it went up first time. Very happy with it all.

[@gtn]

Trust your local shops 🙌

[@DigininjaRobin]

@@gtn The guy in the shop was a bit annoyed he couldn't get it to inflate with the compressor but offered to sort it if the new tape didn't work.

[@gtn]

When the content is this good the police get involved 😉

[@Mavrik-60]

Well now i carry an extra tube with me. The thing with tubeless is any one of those holes can and will come back to haunt you at any time they can and do decide to reopen. People don't realize that leak you just got on your tubeless is an old leak reopening. Keepemcoming

Tubeles tires have increased my confidence for cycling alone as I don’t worry about getting stranded. For me it is as much about safety as comfort and convenience. Fun video GTN!

[@nemure]

If safety is you're concern then you should never use tubeless 😅

[@gtn]

That's awesome! It's great when you have confidence in your tech 🙌

[@zachn6844]

@@nemure just carry a tube with you in your repair kit and do a swap like you would have to anyway with a normal tubed flat. Tubeless is great tech, especially if you have an air compressor it really takes very little time to do maintenance every 6 months or so.

@@zachn6844 every 6 months 😂😂😂😂😂😂😂😂😂😂😂 Latex dries out really quick if you don't make maintenance daily!

[@purelyrecovery]

I use tpu tube in a tubeless tyre. Seems to work quite well. I’m thinking about adding a small amount of sealant to a tpu tube in a tubeless tube, less mess! 🙂

[@elka2palka]

I have tubeless, love it.

[@CS-pz8wq]

Okay I laughed a the end -- getting to purposely mess up bikes as a job sounds like fun, but the idea of doing it to Ollie and Alex's bikes just adds to the enjoyment of it all.

[@larrylem3582]

You have to add sealant every 3-4 months no matter how much you ride. And then it's expected that you wear out and replace your tires every year. If not, you ought to remove the tire to remove the dried sealant that has built up.

[@Bobby-wn5yr]

Day to day yes it is - the reduction in punctures is awesome. However long term, Urgh it’s such a faff lol to deal with lol.

[@MikeRaymond91]

6:40 you actually managed to ride through the gap. Fair play

[@gtn]

Who said triathletes don't have skills 👀

[@SonnyDarvishzadeh]

Tubeless can be mounted fast by knowing the right techniques. Newer ones are tight and need to seat both sides in the middle, then a lever might not be even needed, which you wasted quite some time on it. Used and old tires can get very loose, making them really hard to seat, especially on wider rims.

[@donball370]

Did go tubeless but have returned to tubes. Far easier to deal with the puncture that tubeless didn't seal ... no mess and easier to get tyre off and back on

[@Ocean38Ger]

I took my gravel bike on some forest trails today and got a flat tire. I'm definitely going tubeless next time so I can ride fast again. I hit a top speed of 48 km/h, but had to brake hard on the gravel which resulted in a snake bite. I ended up walking out of the forest 2km with my road bike shoes, was no fun and my friend picked me up at the road. Lesson learned! Stay hard, ride fast🎉

[@chevystuffs5971]

I have run tubeless in two 70.3 tri’s, two Escape from Alcatraz tri’s and Rock Cobbler 10. No flats. Switching to Fillmore valve stems was a help. All my training rides are tubeless as well. It works.

[@andrewword6802]

I love my Gp5000 tubeless!

[@Gixer750pilot]

No squirt of air to get the tube inflated to stop it pinching ?

[@jonasvieth]

Never mind tubeless or tube. The most important thing is that you guys used an Erdinger bottle 👍

you can buy tubes filled with sealant, so it is way more puncture resistant than normal tubes then

[@veganpotterthevegan]

They're terrible at sealing

[@gtn]

You don't get the added advantage of low rolling resistance 👀

[@JimCullen]

My bike came with tubeless and I used it for a while. But the first time I got a puncture, it failed to seal. Rather than deal with that mess, I replaced it with a standard tube. Not very long later, I got a puncture in the other tyre which also failed to seal. So basically, I'm 0/2 for tubless' famed puncture resistance doing its job. So I've completely switched back.

[@veganpotterthevegan]

There's a huge chance you had punctures that sealed so quickly that you never noticed them

[@erikmmartens]

I've had a set of Reynolds rims that came with the bike including tubeless valves. Tried to set it up with Schwalbe Pro One TLE tires but they wouldn't seat. Went back to a bike shop to have my rim tape replaced even though the factory one was tubeless ready. I bought a Topeak air tank and eventually a compressor and when the tire did finally seat, air was still leaking out elsewhere from the rim. A year later sealant was still flowing out from the rim's inner cavities through the spoke holes. Currently I'm using Continental supersonic race tubes. They are butyl but super thin and only weigh 50g. Perfect tradeoff between price and performance, as they cost 9-10€. I notice no difference to aerothan tubes on my TT bike. I rarely get flats and when I do it predominantly is because of glass where I get these nasty holes that not even a tubeless repair kit can plug. At that point I would have to put a tube in to get home, but imagine all the mess with the sealant then... On a Gravel bike or MTB snake bites are a thing, but it only happened to me twice in the last 4 years. You just have to be wary of the lower tire pressure, most of the time you can avoid obstacles that would result in a pinch flat. Unless you are super hardcore downhilling with speed, but personally I am not. I'm riding these bikes too infrequently anyway and then especially I'd have to keep rotating and maintaining the tires if they had sealant in them. BTW with butyl tubes you can totally fill sealant into them to contain the mess and have protection just like with tubeless. Only thing you miss out on is the rolling resistance.

[@Dimashoey]

In my case tubeless tires were very hard to remove. So I converted back to clincher with TPU

[@gtn]

When did you make this choice? The tech has come a long way recently 👀

[@coverchick]

Tubes. I know how to change a flat, it's no big deal. The setting up and maintenance of tubeless is a deterrent for me.

[@panzerveps]

I love tubeless on road bikes, but my lbs (and my local online bikeshop) has been sold out of my preferred tubeless tire for a while.

[@gtn]

What tyre is that?

[@larrylem3582]

Statistics, what is the rate of punctures in the pro peleton now vs. 10 years ago? Hmmm, maybe they were riding tubulars then. I still see the pros puncturing, ruining their races. What stats can be gathered, tubed clincher vs. tubeless clincher?

[@tenaheffernan1368]

I believe the best tubes option would be TPUs rather than latex.

[@nicktaylor1550]

Did I miss the double blind test where you see if you can tell the difference by feel?

[@dylanhunt5368]

I have a bike with a 20 year old tyre and the innertube could be 20 years old too since I don't remember changing it the past 15 years. Then again, I have no need for weak expensive lightweight stuff 😂. Zero punctures and lots of cycling. Another bike had a gaping big hole held together by threads where you could see the innertube, and the tube didnt balloon out and explode until after a whole month of constant bike touring. And it was still possible to repair the innertube and put it back in so im gonna say innertubes are pretty sturdy and simple way to go.

[@nissenalf]

I've been running tubeless tires for four years now and have never had a flat, despite the abundance of sharp flintstones here in Denmark. It's much easier to set up on MTB tires though!

[@knitrundig4663]

It's flint around here that causes the problem with inner tubes. It's hard to see when you puncture and then if you don't remove it from the tyre it's phone for a lift time.

Tubeless on my mountain bike when I'm riding where there are lots of goat heads, otherwise tubes with Slime. Tubes with Slime on my road commuter. Tubes with Slime on my road bike for everyday rides, but TPU tubes when speed matters. Slime works surprisingly well--and doesn't need refreshing in hot weather as often as other sealants.

[@douglasdavis1455]

I decided to go tubeless one afternoon. After a few hours and a lot of mess gave up. Naturally, there is an advantage to tubeless but man it's tricky. Haven't wanted to try again yet

[@mirkocelii5543]

Never had tubless so far, but with my new bike with tubeless ready wheels I really struggle to place the tyre after puctures. I'll probably convert to tubeless soon :)

[@maxLufter]

Did an ironman 70.3 Aix-en-Provence last Sunday. On one of the steep downhill turns hit something sharp on the side of the road and my tire immediately blew up (I had a tube). There was literally a hole on the side of the tire - if it were tubeless tires, my race would be over. In my case replaced the tube and even though the tire needed replacement in the end - I still managed to finish the bike course and had overall a great race. After this experience - only tubes!

[@KS-go2ig]

But you can put a tube into a tubeless tire as a back up, just need to unscrew the valve.

[@veganpotterthevegan]

Why would your race be over?😂 I'd throw a plug in there and I'd be set. If a plug didn't work, I'd use a tube.

[@uaproman]

In my location Tribulus creeping grows and it's a GIGANT problem for the tubes. So, I used sealant in my tubes but this war bulky/heavy/slow. So this year I moved to tubless. And already got a little cut with glass (had to put a patch on inside as it didn't hold heigh pressure) and a few self sealed punctures. Anyways, I'm happy I moved to tubless.

[@robertowen758]

Surely the problem with tubeless is the lack of standards; rim profile vs tyre bead. Is that still the case? I use much treasured Mavic UST.

[@gtn]

That seems to be less of an issue now. There is certainly can be some compatibility issues but it is much better than it used to be. We would recommend giving tubeless a try 🙌

[@DamirUlovec]

Latex inner tubes are no-no when weather is hot. They tend to "puncture" themselves, heard and seen by myself.

[@rkirbyie]

Tubeless or lates tubes - I'm stuck and maybe you can help? I have Ironman California coming up in a few months; a perfectly flat course. My TT bike has 55mm carbon wheels, running 23mm tyres and latex tubes. The 55mm Vision wheels are tubeless ready, but at my weight, on 23mm tyres, my recommended PSI for tubeless would be over the max pressure for hookless rims. On my road bike, I run a super comfy tubeless 28mm tyre on 45mm carbon wheels - where my weight just about recommends a PSI under the max 73 PSI for hookless rims. My dilemma is: do I stick with the aerodynamics of the 55mm wheels with 23mm tyres on the TT bike for IM California, or swap over the shallower tubeless wheels from my road bike, sacrificing the aerodynamics for the lower rolling resistance of the tubeless. A first world problem, I know - but what would you recommend? #gtncoachescorner @gtn

[@mpvsystems9302]

I've never raced on anything except tubulars and have no plans to change. The tire + rim is a lot lighter, they are livelier, they are more flat resistant (no pinch flats), and far more comfortable than a clincher or tubeless of the same diameter. Patching the inner tube is more time consuming, but maintenance is not a performance factor so it does not influence my choice for a competition setup.

[@veganpotterthevegan]

You have a far bigger chance of a pinch flat with a tubular than tubeless

[@jamesmcguckin6288]

TPU tubes all the way,although I did get a faulty one that leaked between the valve and valve stem. They’re great when they don’t leak.I also like latex tubes for the cushy ride quality. Couldn’t be doing with a tubless set up, faffy & messy. No thanks to them.

@@Brkchey Yes, but with my avg 1 puncture a year for the past 10 years (avg 3000-4000km/year) I only have to change my inner tube once a year, and not 2-3 times per wheel to clean the old sealant and put in a new, while also making a mess in the process. I am wondering why does not Continental use their puncture protection ContiSeal tech they have in their car tyres.

[@marinetartenpion]

I would definitely go for tubeless if it would not require a blast pump or CO2 cartridges on the road, and when it happens, then you better be good at seating your tire rapidly

[@veganpotterthevegan]

It's not hard to treat it like a tubed tire in the case of a tire that won't seal. That said, Dynaplugs are incredible. In 80k miles, I've only needed 3 tubes but need a plug every 2-3k miles.

Tubeless is great until the pressures go up. If you’re running higher pressures more than likely you WILL be plugging. Then the sealant will seal around the plug. But sealant at high pressure won’t last immediately

Besides, are all road wheels compatible with tubeless? I think that mine are not but I don’t understand why they aren’t even if I put the rim tape.

[@veganpotterthevegan]

I have a lot of goatheads where I live. Enough that I've double flatted a couple times a year before going tubeless and rarely went more than a few days without a flat. This is with durable, conti 4 seasons. With tubeless, I still get those goatheads but I get maybe 3 flats a year

This crap bullshit again? First let's go with tube tyres. You have on the market bullet proof tyres made tu run with tubes, nails won't go in those, so puncture resistance is waaaaaaay better than tubeless They have little to no maintenance and can be used whenever u need. Cheap and easy to set Now tubeless, they have way weaker and more expensive tyres, they need specific and more expansive wheels and they're dangerous. They can go off the rim since are hookless which is a death trap They have problems sealing higher pressure means sealent sprays and never blocks the hole, cause you know, not everyone run 32mm wide tyres on road The sealent has a LOT of maintenance, you can't leave the bike quite for couple of days or sealent starts to dry out and make a paste inside the tyre that is just solid latex making the wheel ride worst, slower and heavier altering the center of gravity The sealent is toxic, more often than not front wheels punctures get people to get latex sprayed on their face And lastly, on real world you won't find any of these things on the road, you may find a bolt or a nail every now and then if you're unlucky. Is not the common thing and you can always avoid them if you pay attention where you're going on Ps it's IMPOSIBLE to pinch flat a tube if you're pressure is set properly, pump you're tubes always before going for a ride and you'll never get 1 Tubeless can't pinch flat indeed, but who needs a pinch flat when you're whole tire gets separated from the rim causing a guaranteed crash? Oh don't forget if you ruin you're tubeless tyre and you need to put a tube inside to go back home and pump it you won't be able to do it with a hand pump, some people is able to do so after a very extend, long and exhausting effort but not always forcing you to spend even more money on co2 bottles and plugs to seal the bigger holes that yet again, won't happen on a regular puncture resistance tyre like the continental super sport plus 😅
