| Ian stop worrying about your tyres mate, the rear pilot sport on my ST4S looked a lot worse than yours after John Hackett had done a session at Silverstone on it. I take it you are using a 190 rear-that will be why you have the chicken strip-change to a 180 mate you will get loads more grip.
Pressure wise you should reduce your back tyre pressure to 30lb ish for track riding.
Don't worry about MR James comments about Michelin, he just doesn't like them. Have to agree though the AM89's were CRAP.
