I am running Pirelli Diablo SuperCorsas and want to know when it is recommend to replace tires. My tires have more left than right wear due to layout of the last track I rode. On the left my tread is disappearing at the edges (see pics) and some tread has just reached the wear bar on the left side on the rear also. I talked to a tire support at our track and they said I was still good to go. Was planning on doing one more track day on them, but a little concerned. I have not had any tire slippage yet, just one front end chirp likely my fault on the turn. Does anyone run track tires past the wear bar? Probably hard to tell, but from pics would you still run these?
