That's well dodgy...function aside you shouldnt expect that on a top quality tyre i reckon......look at the bottom crack...it has a circular halo all around it as if theres a larger affected area or it has endured some kind of shock......unless youve particularly ridden quick over something particularly sinister on the road id be wanting replacements.
Easiest way to go fast........don't buy a blue bike
