i personally have been involved with a team that ran in excess of 300 laps on one set of these tires. they were used for a 150 lap event, i do not know how many green flag laps, and then for another 180 in practice at the next event. rr was 1/32 and showed cords, rf was 2/32, lf was 4/32, and lr was 3.5/32. the car ran 14.5 new, 14.6 start of next practice, and was still running 15.1's after more than 300 laps.
please feel free to share you own personal experiences with these tires, as clint bowyer said, there's no such thing as too much information.
