Tyre damage advice.

Sorry for yet another newbie question I discovered this gouge in my rear tyre today and wanted some advice on whether the tyre is ok or will need replacing. Looks like it was caused by some glass or similar. Seems to be about 2mm deep or so. The tyre is a Pirelli diablo strada. Thanks guys.

Ooooooh. Tbh I'm sure it looks worse than it is. If it hasn't penetrated the carcas, it might not be optimal for 'unruly behaviour' but, it might be fine for normal riding. However, the best advice is to check with a tyre person. Ok, granted some might try to sell you a tyre and tell you ballcocks but if you smell BS just walk away. Can't really give you an accurate assessment based on these pics.

On the other hand, I'm out and about on Friday ... (check rideout thread )

it wouldn't bother me if it was only on the tread, just a bit concerned as it is between the tread too. I'm having my new chain fitted at GP's on Friday so will ask them to have a look at it. May be out and about afterwards though

Sweet, i'll be in the area doing some filming and set up on the bike so PM us on here on the day if you fancy a ride.

The only problem with taking it to a garage is they'll tell you it's fecked to a) cover their arses and b) sell you a tyre. Best to get impartial advise from someone knowledgable away from a garage.

My gut tells me that's not as bad as it looks, but if it was me I'd also be concerned. Defo get advise from someone who knows tyres.

The other people here are probably right, the damage is probably not as severe as it looks. Looking at it a second time I realised part of what looked dodgy is actually just the flashing from the mold.

But with that bit of rubber being the only thing keeping my backside from hitting the ground I'd be inclined to replace it. I think you'll struggle to find anyone in the trade who'd tell you it was fine, and if they did they would certainly not give you that in writing. I'd at least resolve to change it at the first opportunity.

Thanks for all the advice guys.
I popped it in to GP Motorcycles today and fair play to them they didn't try and hard sell me a tyre. In fact they practically had to talk me out of buying one They said the tyre has got at least another thousand miles or so left in it tread wise, so rather than buy a new one they can just fit an inner tube to it to give me piece of mind.

Generally if you can see cords then chuck it.

If not, keep your eye on it.

No they can't
You will find that lots of people will advise against this, because the tubeless tyre is stiffer, and has ribs inside, with the result that it chafes the inner tube and it may burst.
They also say that air trapped between the tyre and the tube can't get out and may cause it to burst.
They even say the well on a tubeless wheel is different and will leave a gap that may cause the tyre to burst.
