Hello! Here’s a little background before I go into the problem. I’ve completed three tubeless setups this year (road, gravel, MTB). I use WTB tape and Stans valves and sealant. This question is about repair of a hole in a tire, specifically road tires.

I rode over some glass a few weeks ago. Two holes in the front tire that sealed up and got me home at around 40psi. I weigh 150lbs and the low pressure was alright. Tires are Shwalbe Pro1 tubeless 23c (measure 25mm).

I’ve allowed the sealant to plug up several times. The tire will sit at 90psi in the garage, If I pump it up to 120 to test the plug will fail. I bleed it down to 80for the ride, but at the coffee shop I can see weeping sealant from the hole.

Last night I removed the tire and patched the inside using a Park VP-1 vulcanizing tube patch kit. I have my fingers crossed it adheres and is permanent. I do t want to have tontoss this tire in the garbage with so few miles on it.

Does anyone else have experience repairing tires, especially high pressure road tires?

I want to try a Dynaplug setup but they’re pricey and I need to bring it into Canada. Also, I’m wondering if the little tail that sticks out will give feedback every revolution because of how it will slightly protrude from a slick tire. (Actually, I’d appreciate very much feedback on Dynaplug products as well).

Thanks for reading!

FWIW I wouldn't pump any tire, tubed or tubeless, to 120psi.  I'm running a set of the Schwalbe Pro Ones in 25mm at 70/75 and think I could safely go a bit lower. Velox makes a tire patch kit available from Chain Reaction. And while I have the Dynaplug and Genuine Innovations Plug tool, I haven't had to use them yet. Having said all that I think the tube patch should work fine. I've done that with high pressure tubed road tires and had no problems.

I've repaired tubeless cuts with tube patch kits too, albeit on bigger tires that are lower pressure.  Just to be on the safe side I added some superglue to the outside cut too, but that probably doesn't help much.  They held air fine.

 

Schwalbe would probably recommend replacing the tire but they'd also recommend that after each ride in order to increase sales.

I repaired Vittoria Corsa Speeds with the same Park Vulcanizing Patch method and they have held fine.

I have seen others use cotton 'Butcher's cord' in a similar manner to Dynaplug and then use scissors or nail clippers to trim the tail. It is approximately 24,350,234,905x cheaper. This kit works fairly well and you could replace the bacon strips with cotton cord for as long as you didn't lose the insertion tool.

Sounds like the holes are small, as your sealant is basically handling them.  Could try cleaning up the small hole(s) on the inside of the tire real well, and applying a dab of Aqua Seal and let it dry good, then add sealant and proceed.   Aqua Seal dries flexible, sticks really well (if the area is clean) and am guessing it will work (for small holes) as it works wonders on waders and dive suits for me (I haven't tried it on bike tires) .... worse case if you try the Aqua Seal (not counting the potential of the glass cut on the outside opening up causing tire failure/crash, which you won't solve with any patch) is you will be no worse are then are now, sealant will cover small stuff.  

Personally, if I was forced for some reason to not simply replace the cut tire avoiding a potential crash (the recurring weeper would scare me...and I hate broken bones generally all the time, but particularly during riding season),  I'd try Aqua Seal  before punching a larger hole into a road tire with repair tool.  

Last...If I was riding on the road in a fast pace line and knew I had a glass cut damaged tire, I would replace it at my next opportunity .... I have hit the deck, and it rarely ends well.  

Don't mean to offend in any way with the crash stuff ..... Respectfully, I just don't like crashing or having others crash in front of me.  

Ignoring all this or the potential of Aqua Seal fixing you up, I like Volsung's approach...if it's a tiny hole.


Hope this helps

Hmm, I never thought of Aqua Seal and sure find myself using it plenty after moving up to higher end wetsuits. I'll try it if I find myself fixing a tire AND wanting to pull it off the rim. Thanks.

Finally had a chance to use the Genuine Innovations plug tool and it worked well. Easy to use and the plug seems to have sealed the leak. Luckily I noticed some sealant leaking just before going for a ride so I got to play around in the comfort of home. The hole looked to be about an eighth of an inch long, possibly a glass cut which the sealant did not seem to be sealing. Anyway I inserted the bacon strip and trimmed the end and did my ride with no problems and as of tonight the hole appears to be sealed.
