View Full Version : Repair Tubeless Tire with Sidewall Cut ? ...

So I have done some searching online and found plenty of folks patching tires what have experienced tears/punctures, beyond which stans will not seal.

Sadly I experienced one of these such tears at the Mohican race this weekend, luckily I had a tube, and after about 5 minutes lost, tubed the front wheel and kept trucking.

So that brings me to the tire, it really is pretty new and does not have much in the way of use, and I would like to try and extend its life some, I think that would be swell.

Have any of you had any luck using rubber patch kits and patching the inside of the tire? I am worried that with being on the sidewall its "risky" to the integrity of the tire to do. I can see patching a large puncture, that wouldnt be to bad I wouldnt think, however the sidewall has me thinking that I might just have to "junk" this tire, which is a bummer...Maybe the EXO sidewall on this Maxxis Ikon didnt help that much.

Any way here is and image of the cut, chime in if you would like with any experiences.

That's a tough spot to fix. I've had success using a tube patch on both sides of a tire, but that was on the tread, not the sidewall. Give it a shot, and try it out. But the days of it being tubeless are gone.

I've patched tire like that before. Mine was cut more parallel to the rim so is didn't extend towards the tread, but it looks like most of the damage near the tread is superficial. The actual cut on the side wall and relatively small. My tire had a much larger cut and it held up fine.

I patched the inside of the tire and used the tube for the first ride so that the patch would be held against the tire. Then I pulled the tube and went back to tubeless. No issues at all.

Even though I run tubeless with sealant, I carry 2 Park Tool Tire Boots (http://www.parktool.com/product/emergency-tire-boot-tb-2) in my CamelBak at all times (with a spare inner tube) - they have saved me from long walkouts twice. They are very light but super tough and they hardly take up any space.

Way back in the day, I used to carry a couple of cutout sections of an empty toothpaste tube that served the same purpose - place inside the tire, insert spare tube & inflate and ride on.

The Park Tool Tire Boots even have adhesive on the back side so they stay in place while you insert the tube and inflate.

With your particular trauma though, even if I was able to boot repair it trailside and ride out, I still think that would be my last ride on that rubber...
