I got 19,000mi out of the factory delivered PPS 300 tread wear. Might have stretched them a little further but do a lot of high speed interstate driving.
The 100 treadwear 275X17/315 X17 on the 2250lbs 488WHP Cobra last 9,000mi.
Expect the Cup-2 treadware 140 would fall someplace between them but closer to the Cobra.
This link is a current thread in the M3/4 section. About a lightly experienced driver testing his new car at the track. Why its relevant beside being well written is it talks about factory PS4S tires dealing with S level horsepower quite a bit.
