Got to the bottom of my road today and found a rip in the side wall of my conti GP4000s and a lot of air leaking out. I have patched it up with a patch and some emery cloth (strong none flexi material to stop the bulge) but is there a more permanent fix or should I just bit the bullet and get a new one.?

Get a new one, high pressure and damaged tyre = painful future

sew it with dental floss, patch in the inside with a large puncture repair patch

Get a new one, high pressure and damaged tyre = painful future

That’s what I was thinking. Always bodged MTB ones but I’m a bit worried about doing the same with a road tyre.

No idea how repairable it was but riding a tyre I’d sewn up at 40mph downhill doesn’t appeal to me. Either it works and you’ve saved a few quid or it fails very painfully. Your choice?

New tyre! 100 psi can explode , bad to fall on roads too, ESP with cars around.

Had a GP 4 seasons with a rip. Used a tyre boot to repair. Only took a few rides for the boot to fail. Did it again (had no money to buy a new one and payday was a couple of weeks away), this time it went pop as I was riding along road

Jesus, I’ve just replaced a newish tyre with a 3mm glass cut and just one thread in the carcass cut through. I simply do not want to be in any doubt about it.

I’d definately be looking to replace at first opportunity for all reasons above – but the best bodge has to be a folded tenner between tube and tyre

Depends on the size of the cut. Superglue makes cuts vanish, serious, you will find it almost impossible to find the cut once its been superglued properly. Obviously not a ten inch rip, but globati , 3mm glass cut can be fixed.

I’ve know of someone who’s sewn up a tear in the sidewall of a GP4000s. It’s been fine since but I’m not sure I’d like to try it. I would say that if you’re going to do it, put it on the back.

Its worth noting that tubular tyres are sewn up along their entire length and they hold to 200psi! However as i said, a rip is a bit different and id question the longevity of a repair in a place where it could be damaged again.

Park tyre boots seem to work well; currently running one inside a badly cut Gatorskin (roadside fix) to see how long it lasts.

Paper money is a reasonable alternative (retains its strength when wet).

Stato, the difference is that they are designed to be tubular and the stitching is against the rim, with glue holding it on. No on an unsupported very flexible sidewall.

Anywhere near the bead and bin it

My last one on a nearly new tyre, luckily I wasn’t going downhill.

A bit of a pop bottle to make a tyre boot works, it’s a ghetto tyre boot.

I sewed up a tyre then rode if a few times to show I had faith in my work, now it’s just used on my turbo where it’s doing well.

Went through this myself. Started a thread, “bin it” said the majority! “Fix it”, said the few..
Fix attempted, another fix attempted..etc.
Binned it.

I used a puncture repair patch on the inside of the tyre and superglue on the outside to repair a pro 3 race. I’m fairly okay with it on the rear but wouldn’t use it on the front. It’s in the spares box as an emergency tyre that I would use for a couple of days maybe if I had to wait for a new tyre.

you’re mad to consider anything but a get-you-home fix imo, would be very difficult to keep the tyre shape even without the safety risk or inconvenience of it blowing 30 miles out.

OP tubeless patches don’t stretch and may work.

May be no logic in it but I’m wary of fixing slashes in HP tyres.
