Repairing a tub less tyre puncture?

100Suns

I have Hutchinson Atom tubeless tyres on (at the moment). I rate them highly on rolling resistance, grip and comfort (they can be run under less pressure than clinchers). The biggest attraction is less risk of pinch flats.

Well today at Stamullen 6 km into the event I hit a small stone and picked up a pinch flat. The hole is in the side wall. Has anyone repaired a hole in the side wall of a tubeless? If so, did it stand up to further abuse over a long period any any tips on the best way to do it to protect the integrity of the tyre?

Thanks

Generally sidewall puncture = junk the Tyre, whether tubeless or not. It was probably a rip rather than a pinch, no?

Thanks blorg. I feared binning it would be the outcome. I've taken off the tyre and there are two small holes-one at the top of the side wall and one level with the rim. Classic pinch flat. The top hole is minor but the bottom is has the hallmarks of a right off.

As a matter of interest, do you put the gunk stuff inside the tyre when you run Tubeless or do you just rely on air pressure? I have the gunk stuff on the MTB wheels and it is supposed to fill most holes (according to the videos on Stans).

I use the gunk. It's fine for retaining pressure by preventing leaking at the rim but didn't seal the pinch flat.

BTW hope you got sorted with gear (club) yesterday.

That's a bit of a PITA - are road Tubeless tyres more fragile than MTB ones I wonder??? I was seriously considering going tubeless, but if it's just for the sake of buying more expensive tyres I'll stick with the Ultremos

Aah, was that you in the shop? Wanted shorts, but ended up buying a Gillet. New batch of shorts are on order apparently.

don't go tubeless without the gunk!!!!!! Personally i find tubeless great and the only way to go, you can get reinforced sidewall tyres, slightly heavier though!!

Tubeless + gunk for MTB every time for me. Only just got a road bike so I'm happy with tubes. Any more expense on bikes and I'll be divorced!

Personally unless the tear is very big I'd put a patch over it (a bit of heavy gauge plastic like DPM for a house) stick in a tube and use if for a training tyre. No point binning a new/ish tyre that cost you dear!!

Depends on the manufacturer of the tyre some can be patched on the inside with a heavy duty patch and glue but only if the tyre has been vulcanised on the inside,not sure about your one,but if its a big slice I say bin it:(
