my tyre, rear Pirelli diablo, has only done 400 ish miles, and I noticed a very small panel pin type nail in the tread,
I pulled it out and .......... ssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssss

it is bang in the centre in a thick part of the tread, I understand that the tyre standard is not to repair ZR tyres,
but it seems to be country dependant,
any professionals out there ? or anyone know for sure ?
