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 know of a few big thorns that I've gotten in my MTB that I had to pull out that sealed instantly. I know I've had a few punctures on my road road bike as I've seen small little holes with sealant that has leaked put. I did not even know I had punctured. I ride in South Africa and the roads are terrible in my area and they are littered with broken glass. I will never ever go back to tubes. After having about 10 punctures in 2 months on my road bike, i was ready to give up! with tubeless, going over a year without having one has been amazing!

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.

Only had to add air to the front a bit but so thankful for tubeless tech. That would’ve been a rough and long walk home through the desert if I still used tubes lol. And so far so good with 30c tubeless road rides with the crappy roads in these here parts.

Fantastic! Tubeless really can get you out of a sticky situation.

@fpainchaud350 Год назад

I have been running tubeless on my mtb and my gravel bike for quite some time now and it's almost a setup and forget type of thing. On MTB's it used to be that every time we would go on a ride someone would get a puncture (snake bite, usually). Thankfully those days are gone!

@yiannispapelis8260 Год назад

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!

@jaylumbago559 Год назад

I’ve seen a lot of these tests where the sealant works magically but I had many punctures with holes too tiny for a tire plug which still didn’t seal. And when they eventually seal at a very low pressure it rips right open again when you pump the tire back up. Am using Stan’s Race by the way.

@russellspeight5175 Год назад

Try the Mariposa sealant additive to add a some granularity to the sealant.

@danyboyno1 Год назад

i didn't find that stans worked very well on road tyres....better on wider gravel/mountain bike tyres. Continental sealant worked well but I run with Peatys now on road and i've found it works very well. With plugs......they can take some force to push through the tyre but they do work very well, again I use Dynaplug as I found the "bacon strips" just got messy and dynaplug is s neat package.

@jamesthomas2196 Год назад

I use stan’s race too, but it needs masses of shaking (at least 5 minutes) before putting it in the tyre otherwise the granules remain at the bottom of the bottle and don’t mix properly with the sealant.

@JohnnySantoDomingo Год назад

Have had several of those punctures as well. I’ve only used Stans DART plugs and the trick I’ve found was to just peel off a “leaf” from one of the darts and use the tool to work the leaf into the hole where the full plug wouldn’t get through. It’s frustrating at times but the DART seems the best tool for those punctures rather than “bacon” strips or dynaplugs. Using normal stans in 30c tires and that method has worked 95% of the time and being able to get back up to 50psi

@andrewmcalister3462 Год назад

A sidewall tear is pretty catastrophic with tubes as well.

@ProfGoodlife Год назад

@@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.

@eduardorichard4845 Год назад

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.

@erics9214 Год назад

After a few years of resisting the cost and faff of tubeless tires, I'm a complete convert. Yes, they tend to be harder to mount/dismount. Yes, they can be hard to get to seat. But as Ollie's experiment shows, they can almost eliminate those common, small puncture flats. Also, though maybe just my imagination, they give a certain suppleness and compliance to the tires that improves ride quality.

@Jean-jk4zv Год назад

Yes and the bigger tire size you go the easiest is it to mount. That's why it's hard for road tires and flawless with gravel and MTB.

@paulappleyard5832 Год назад

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.

I don't want to be stranded by the roadside trying to get a tight-fitting tyre off the rim. I like my bikes to be easily fixable by the roadside, and in the end it's no trouble to carry a couple of spare tubes and a puncture kit everywhere.

@jackothekingUK Год назад

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.

@ragwort3369 Год назад

@@jackothekingUK I bet trying to fit a tube in a flat tyre full of sealant makes a hell of a mess, though! I can't see the point of going tubeless if you still have to carry spare tubes just in case. Admittedly, Ollie's demonstration in the video shows how effective the tubeless system is, but I still can't see enough advantages to outweigh what I perceive as the disadvantages. Mind you, most of my riding is solo and not really time critical, so there is that.

@jackothekingUK Год назад

@@ragwort3369 I used to think the same thing, still got to carry tubes and a pump, what's the point?

I have done over 20,000 miles on tubeless. Only had to stop to put in a worm 4 times in all those miles and always got home. Putting a worm in the tyre is much easier than changing a tube (especially when you have cold hands in the winter), and you don't need to take it off the rim. Other than those 4 times, I haven't had to stop once for a puncture in all that time. It's a no-brainer

@chris1275cc Год назад

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.

@csabakrisztan2300 Год назад

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...

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.

Congratulations. Your tire sponsor will give you new tires now. Clever👏

@larsholst6147 Год назад

impressive. might convince me to switch from inner tubes at some point. i just wonder, since this test was run in dry weather, how the sealant would have performed in rainy conditions?

@IAMsterdam1071 Год назад

Tubeless is nice for people that have regular flats. For riding on the road here in the Netherlands they are just overkill. I have a flat maybe once a year and probably less.

@khazza930 Год назад

I'd be curious to see how things go if you kept riding right after the punctures. Would the sealant still manage to dry up and seal the tyres under the pressure of a rider's weight?

It works

@richdyer2000 Год назад

been riding tubeless on my mtbs for around 7 years. Had to use a plug a couple of times, but never had a ‘proper’ puncture in that time.

Was that genuine Ollie B blood on the GCN stinger?! Thanks for your service brother!

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)

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

@haraldbleck440 Год назад

how old is the sealant? will it work after 4 or 5 month or in the winter?

What sold me was the time I rode to the top of our hill to take a photo, looked down and I was in the midst of a big prickly pear cacti patch.

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 want to know what happens when Granny comes back in the Mini: will her tyres survive the GCN Mega Stinger of Doom - that Ollie helpfully left in the alley - also?!

@rg807 Год назад

Tubes: 5 mins to change a tube once or twice a year. Tubeless: giant mess, need to "top-off" sealant. Need to very carefully clean the rim before mounting a new tire or it won't seal, and finally, sealant spraying all over my bike. Gravel, mtn, sure. Road, no, not worth the hassle.

@marty197666 Год назад

I thought I had a sealant failure last year. But when I got home and looked closely it had been a sidewall fail on my Michelin tyre. Back to conti!

@HumdingerB Год назад

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 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.

@glensmall1 Год назад

Tyre pressure matters for sure. I had muc off in a set of p-zero tyres, but at 110psi (I'm chunky), and the pressure just pushed all the sealant out. After I dropped down to 80psi, I'd say it performed better.

@piandbash442 Год назад

110 PSI is well above the max recommended pressure for the P-Zero tyres even for a heavy rider. Stick with your 80 PSI, much better all round (so to speak).

@martinarnsten4203 Год назад

The TL fails I had was not like a circular hole but like a rip.

@kannibalkev Год назад

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!

@jimjamesi1598 Год назад

What sealant did you use?

Been riding tubeless for about 4 years now. Last season was the first time I tried Muc-off. Worst season I have had in terms of punctures. Back to Stans for me

Can you do a video on beryllium bike? Will it be lighter than carbon fiber? (carbon comes after beryllium on periodic table so i think it will be lighter).

@chrisfromfrome9016 Год назад

Love tubeless, even the old getto versions when they worked!!.. Ps. You should of ridden the pothole in the other direction!....

@clarklowe5632 Год назад

I had a nail go through my tire and rim once. Held air. Though not fun to ride on plus needed a new wheel since my carbon rim was destroyed.

@xtrailz Год назад

70 that's still very high for that meny punctures. I still prefer road cc´s test thy did. The Silka sealent seald a hole from a 7mm screwdriver. that was impressive

@driventomadness117 Год назад

I run tubeless front and tubed rear - the only flat i had in three years was the tubeless. After WWIII trying to remove the tire i finally manage to stick a tube into the sticky mess and kept riding.
