Tubeless tire repair
 

Long story short, I punctured my rear tire on my road bike at some point, but I became aware of it on a 160km ride about 40km in and every 20-30 minutes thereafter I’d get a short blast of sealant all over my leg, and of course the seat tube and rear triangle, with the puncture ostensibly sealing in between these “blasts.” Not to mention, several of the guys I was riding with commented that they had also been sprayed with the “milk”…and I had to endure a few bad jokes about certain types of movies at the pub after the ride. I put a bacon strip in it, and proceeded to take off on a group ride with he clubs yesterday, and 2.5km in, the bacon strip came out of the cut, and the tire deflated.

There is plenty of tread left on the tire, and I don’t want to bin it if at all possible, but I am not inclined to retry the bacon. I did a quick search on repairing tubeless tires (using a tube patch applied opt the inside of the tire, sanded down, cemented in place), has anyone tried this hard any experience? It strikes me that if there is a good bond so air and sealant can’t sneak past and come out of the puncture hole, this should be fine, since the air pressure will certainly continue to keep the patch in place. I’ve already applied a patch, and am going to let it sit for a day or so, then remount the tire…unless there is some definitive experience that this is a bad plan. Of note, the tires are Tubless ready and are being used a hooked tubeless rim (crotcheted).

It sounds like you have already done it. Yes, I would be putting a patch on the inside of the tire.

Right. Have you personally done this, or are you just offering a helpful bit of advice on where to place the patch?

I have personally patched the inside of numerous tubeless tires and never had a failure of the patch. At least two of them had two patches side by side, because of a pinch flat, on MTB tires. I don't like to leave the bacon strips in the tires, so I usually take them out when I get home and patch the tire on the inside. I clean the area of any sealant, abrade lightly and wipe with acetone before applying cement and the patch.

Exactly what I did. Good to hear. I will remount the tire this evening, and get it refilled with sealant. Thanks!

I will do this for very small patches, but would use a tubeless-specific patch on a larger hole. I prefer the dynaplug to bacon strips, and have never lost one after installing. If I were to have a hole that the plug could not hold, I would want a fabric-reinforced patch that would resist separation in the tire. This would be especially true for the higher pressures in a road tubeless setup. A regular patch could potentially herniate through the tire casing like a regular tube.

Thank for the link. The patch I applied “looks” exactly the same as their patches they show in the picture…not sure if they are identical, but they sure look very similar.

The standard Rema patches have an orange border.

I don't think that you would have the fabric-reinforced patches on accident.

Patch it from the inside, don't leave a plug in. Yes I have done it more than once.

Definitley not. The patches had an orange border but no fabric that I can see, just butyl/rubber.

Had a little problem last year:

Horrible clattering noise but the tire didn't lose air

When I pulled it out it turned out to be one of these
Got a patch for car and motorcycle tires (like the kind you get at an auto parts store), cemented it on the inside, and ... 1200 miles later I'd completely forgotten it was there until this post reminded me of it.

That’s good to know…I had heard of folks doing this with MTB and larger volume gravel tires where the pressures are much lower than the 72-75psi I was running on the road. But, conceptually I don’t see it being different, just wanted to make sure I wasn’t undertaking a fools errand trying to patch tires that will run at higher pressures…also good to know about the fabric reinforced patches. I ordered some yesterday. Thanks for all the replies.

Nice that Rema have got with the program and made smaller bicycle tubeless patches,

I'm running 78 and 87 psi. My current rear tire has two patches on the inside. The trick is to make sure you clean and rough up the inside where the hole or small cut is, use rubber patches and vulcanizing cement. Also put a dab of cement in the hole/cut on the outside if you can. Some are hard to find. After it's totally dry, mount and add sealant. I have 100% confidence on my patch repairs.

I use this. No mess. No glue.

I had good success patching a 3/8" sidewall cut in a WTB Resolute. I superglued the cut and used a large automotive tubeless patch from Autozone which was thicker than an inner tube patch but more flexible. It bonded so well you could see the black patch through the gum sidewalls. Be very careful sanding/roughing the inside so as not to cut through the threads. I have also used a inner tube patch on a smaller cut, which worked well.

Will these patches still work with a non rubber inner?
I'm running Vittoria corsa graphene 2.0, they're a cloth / cotton inner with a rubber tread basically glued onto the outside..

​​​​I have a noticeable little cut on the tread which I havent been able to seal with sealant or plug + sealant.
I was considering superglue, but I feel like that would just work its way loose eventually..
And since it's not a rubber inside, I'm not sure if these inner Tyre patches will do anything?

i don't know if that will work, but its easy to test. i have seen on the web people sew up a bad cut before patching it. Maybe that's a worth search.
