Just replaced my tyres on my track bike as they were blue & one had a bit of a slash in it! Not too scrubbed but not looking good to me but I would ride them on a road bike... Or were they? OK a small slash is a no go but how blue is blue. How many cycles do tyres last bearing in mind a 7 session track day sees a good 6 odd hours of warmer time. What do people think?
