When you get a puncture on a tubeless tyre it can be tempting to take the old tyre off and simply replace it with a new one. But it doesn't have to be this way! Alex shows you how you can not only fix the puncture but also keep your tubeless tyres going like new!

Issue I have with this - Self adhesive repair patch is specifically designed to patch the tube and depending on brand, most of them work absolutely great. But I would really like to see long term test of sealant on the glue, because I would imagine that in time, sealant can weaken adhesion of the glue and wash the patch off. It was never designed to be coated in sealant. As a get you home - fine. But restoring your damaged tire back? Also I used tire boot from ParkTool in the past and it works great to save the tire, BUT - adhesion to tire is not easy as tire is not best contact material. Main reason why tire boot works great is that tube is holding it in place and creating constant pressure on the spot. Without a tube and with sealant theoretically spoiling the glue, I can’t see it would work without longer term data.

It _might_ work. The difference I see is that, when you patch an inner tube, air pressure is working to push the patch away from the hole; when you patch the tyre, air pressure is forcing the patch into the hole. However, I too am suspicious of the advice to use a self-adhesive patch. They're great to get you home after a puncture but I don't see any reason to use one when you're sitting at home with a full choice of available materials.

Oh just give it plenty of pressure during curing by puting it under a table leg for 2-4 hours.

This is the first time I have attempted to repair a tubeless bike tyre. Where I live, we have a lot of road hazards, especially glass. and I ended up with a 3/8 cut in the wear area of my rear tyre. This repair went better than I expected. I used a good grade Upholstery thread, A medium-sized slime patch, Cleaned the area with Isopropyl alcohol, reinstalled the tire on the rim, with a tube installed. and aired up to 30 psi. I will let it sit for 24 Hrs. Thanks for your video, It Helped. Can’t Wait to see how well this repair holds up. Reply

As much as I love the feel of tubeless tyres on a road bike I’ve reverted back to inner tubes. In the last 12 months I’ve gone through 3 tyres all due to sidewall cuts. Patching is hit & miss. They all fail due to higher pressure that you need to run road tyres vs gravel & mtb tyres. If the technology improves I’ll jump back in but for now I’ll run tubeless on my gravel & mount bikes.

I’ve had good results using the sidewall of an old racing tire (the part that says Pzero in this video) as a patch. Glue inside to inside using conventional vulcanization cement or contact cement. The hole I patched was about the same size as the one shown here but it was in an ordinary tire (Conti 5k) with a tube. The tire sidewall is thin, flexible and butyl coated, yet remarkably strong and stretch resistant, so it makes an excellent emergency boot, as well as a patch, when glued in from the inside.

Gorilla tape! I had a little slash from some sharp piece of city street debris that wouldn't seal, even after I jammed a Stans Dart in. Took it home, cleaned the inside as Alex has, just put some gorilla tape over the dart on the inside. 2 years later, it's still going strong even though I've ridden plenty of rooty and rocky trails. Honestly for something like a slice where you don't have a chunk of missing material (and in that case you would want to use a plug), just gorilla taping it seems like the way to go, it'll hold the structure of the tire together better than these smaller patches. Sealant will manage any pinholes.

Alex you are an Ace at repair! Absolutely stellar! Repair rather than replace. Its better for your purse and the environment. That is all great but a flat on the road with tubeless is a different challenge. I tell tubeless enthusiasts to carry a tube for the on the road repair when their sealant has dried up or the hole is too big for the sealant to meet expectation. I tell long distance riders (tourist), gravel adventurist and mountain bikers who use tubes or go tubeless a side wall cut can be a disaster. There is road repair if you are prepared. Get an old smooth tire, cut a section about 8 inches ( 20 cm ) long. Cut off the bead. Make sure it will reach from one bead to another on your tire. Carry it with your spare tube and tools. When you get a side will cut, put your tire casing between the side wall cut on your tire and inner tube. It may not be ideal but it will let you ride home. When you are out in the boonies your cell phone is not always a backup solution. Walking your bike home is never fun!

Goo Gone Pro Power (not Goof Off). Dissolve sealant thoroughly w/ Goo Gone. clean that residue off w/ Dawn. Wipe area well w/ Acetone. you should now have clean rubber ready for scuffing, gluing and patching....or self stick if you like. Happy riding.

This procedure will also work on a clincher tire if you are worried that the hole will cause your tube to bulge out of it. If I need a boot, I use what is left of a cotton casing from a 1980's Tub with the tread pulled off. (Back in the 80's, Vittoria Tubs had their treads glued on, so it was easy to pull them off without wrecking the casing....Tubs now have their treads vulcanized on)

@phil_d
@phil_d Жыл бұрын
Having a hole that the sealant cannot plug is the worse thing about tubeless tyres in my experience ... until now! Having to pull the tyre off the rim breaks the seal made by the sealant to keep the system airtight. Most sealants are natural latex and as they dry it becomes a tedious job to clean the rim in readiness for re-installation. The worst sealant for this is Silca's with it's carbon strands that bond to the rim. Awful stuff for road tyres. If you use a synthetic latex sealant it stays liquid for longer and cleans with good ol' water. Pop the bead, run a hose inside the tyre and you're pretty much done. I use milKit which also has fibres within the sealant and the pressure retention is amazing with Hunt alloy rims (that leak air on the butt joint without sealant) and Hutchinson Fusion5 Performance.

I wanted to inform you that a lot of Part cleaner sprays are very combustible and this information comes from the Wikipedia (Under Danger) Rubber and some types of plastics are decomposed by brake cleaners by removing binding components. This has the consequence that the rubber will appear unchanged at first; however, it will become brittle, and after a few weeks to months cracks and fractures appear. Years ago, I also used a parts cleaner on a chain and after a month the plating came off completely and the chain rusted. I will never use a parts cleaner on a Bicycle ever again. Save the parts cleaner for your car’s metal parts ok.

I tried this exact method a month ago in a MTB rear tire (maxxis ikon skinwall) 3 times (40 to 60 psi max). 3 different hole size. It didn't work. Well, it worked for about a week, then the sealant starts to degrade the self sticky patch adhesive I guess and start leaking until it gave up and blow up like a proper unsealed puncture. Have to plug then again. The maxxis ikon are like this pirelli p zero inside. It's like a "threaded semi rubber cloth ish" texture and the patches don't stick too well. I guess that maybe in a all rubber inside tire, it may work fine, and even with a classic inner tube patch kit. I'm not saying it won't work, that was my experience with this. Maybe for some combination of tire/patch it works just fine.

Nice video as usual Alex, but here's my question...if tubeless is all it's cracked up to be why does a puncture that's too small to see not just seal by itself!?. I recently spent 20 minutes at the side of the road waiting for my tubeless tire to seal, but eventually had to put, yes, an inner tube in the thing!. It was a tiny thorn puncture and it wouldn't seal. Now we've all seen the GCN videos where tubeless is put to the test by 6 inch nails and M4 screws - and the tire seals every time!!. So what gives?. Is it just a crap-shoot whether tubeless seals or not, or do some tire/sealant combinations work better than others?. Thanks

Hi Tony, thanks for your comment. Tubeless tyres are not without their downsides too and one of those is that with so many tyre and sealant options and variables such as the volume/age of the sealant used everyone will get a slightly different experience, for better or worse than we see online. The punctured tyre example i used in the video was of a reasonable size and i hoped/expected it to seal at the time, it did, but only enough for me to limp the 15min ride home and wouldn't hold air at high pressure. Just like most products there will be some you have a great experience with and others not so much. In my experience, always carry an inner tube for back up as i have had little successes with roadside plugs. Hope this helps you out. Cheers

In videos where tyres get repeatedly stabbed by larger and larger objects this is a good way to test the sealants theoretical ability to repair a hole. However in these videos none of the tyres have any loading on them. When the tyre is loaded (ie sat on your bike pedalling along) the tyre is constantly being loaded and unloaded in unequal amounts. This causes the tyre casing to flex. This flexing of the casing has the effect of repeatedly reopening the hole the sealant has just fixed, so it tries to fix it again and again and again. This combined with the low volume / high pressure of a road bike tyre means in reality sealants struggle to reliably repair anything larger than a pin prick. I run tubeless in my mountain bike and gravel bike but it will be a very long time before I decided to try road bike tubeless tyres again…

This method doesn't work on road tubeless tyres: 1. inner tube patches cannot hold the pressure and will pop out under high pressure. 2. self adheisive patches cannot withstand the corrosion of tubeless sealant and will debond after a while(they only work when sandwiched between inner tube and outer tube). The method that does work is using vehicle tyre patches glued with vulcanizing fluid.

For small cuts that did not damage the structure I use Pattex Power Repair. First I clean the cut with brake cleaner, then I fill the gap with glue (the tire is mounted on the rim and slightly inflate it with 45 PSI), then I wrap some tape around the tire and the rim, then I inflate the tire with approx. 90 PSI (so the cut is pressed together). After the next ride I cannot find the cut again. Where can I get these patches with inner tube material mentioned at 00:01:41? Does it have some kind of structure, so it is possible to repair even larger cuts? Even those Park Tool boot patches don't have any structure, so they are just good for getting home, but not for repairing the tyre, as they will pressed through larger cuts. I still use Continental Supersonic tyres in combination with Vredestein latex inner tubes (dugast latex inner tubes seem to be the same), and as they unfortunately are not longer produced any more, I don't want to throw them away before the tread of the tyre comes through. Any repair kits for tubeless tyres are just the same as the patches for inner tubes - just some rubber, no structure like the tyre has.

I tried the shoe goo after Doddy made this video years ago. It did work and last for 3 months on a Vitoria corsa speed. Of course it let go when I was loading my bike to go to a race where I scrambled around like a madman getting a new one mounted. But it does not work on a GP5000 or a Schwaben pro one (previous generation). Whatever about the inside of those tires that is different it won’t stick.

Same way he showed. It depends on the sealant, but if you're using Stan's, you can wipe it out of the tire pretty easily and remove any dried that's remaining. Then just use alcohol or brake cleaner to remove any residue. I just did this a couple months ago on a tire. Patch is holding perfectly.

Hi Alex, the same thing happened to me so I want to fix my almost-new tyre. Trouble is, I needed to get 2 things I didn’t have, flexible glue and tyre patch material sheet (everything else mentioned I have). I went y to several bike shops but none of them had these things or TBH knew what I was talking about, they just said to buy a new tyre. So can you tell us where to get the patch material and the glue (or even tell us the name of glue). Thanks.

Why no vulcanizing cement? Also, for all types of patches, always “stitch” the freshly applied patch by rolling the edge of a coin over it, do it again at 90°. A knurled edge U.S. quarter (~1” dia) fits in a patch kit, I'm sure every currency has a suitable coin. Ask the old guys you've been having on, they know.

I patched up a tubeless tire a few weeks ago and got a special tubeless repair kit for the job. The stuff to glue on the patch was blue and seemingly different from the vulcanising solution you get in normal tube repair kits. Would the vulcanising solution also work on a tire?

@Martin Arnsten what @@chrisridesbicycles said! Use the "Special Blue Cement" Tip Top do kits The blue stuff is the same as what car tyre places use to fit tyre plugs etc, it is diff due to tyre rubber and inner tube rubber are different and "inner tube patch glue" doesn't work well on tyres. So always use the blue stuff on tyres. I also use inner tube feather edge patches on road tyres as they thinner/light, as holes are gen smaller one road tyres. MTB tyres I use the patches that come with the Tiptop kit. I also patch a hole if I notice (lose of pressure/sealant lose) even if the sealant did it job in the end.

I would love to see a roadside repair of tubeless road tyres for when the hole is too much for sealant alone. I know tyre worms exist but I can't understand how you'd be able to push one through the tyre carcass without either damaging the rim tape breaking the bead meaning that I probably couldn't reinflate the tyre on the roadside. Knowing my luck I wouldn't be able to remove the tubeless valve to fit an inner tube either. Thankfully, despite having ridden several thousand miles on tubeless road tyres to date, I've yet to have a puncture that the sealant didn't seal. 🤞🏼
