Could you please advise whether the rear tyre on my track R1 is still useable. It has had a couple of very hard days at the track, the last being around the Brands GP circuit.
The right-hand side has a lot of wear and has (in my opinion) squared off quite badly.

We wouldn't go near another track on that tyre. It may be OK for a bit of light road riding, but it won't feel very nice turning into a right-hander.
They're the old style Super Corsa, too, so god knows how old they are!
