i dont recal saying they didnt wear...i said i used 1 set all day
the tyres wore but the grip came up and the soft m3 meant i didnt lose any traction so felt no need to change tyres,certainly not for my skill level anyways.
i didnt think it was that dusty,maybe our cars were finding traction where others struggled,all i know is that i will be sticking m3 crimes on again then maybe switch to HB megabits in pink if the track cleans up.
