Anyone have a theory for this phenom? I put on a set of Bridgestone Potenza S04 Pole Positions about 9k miles ago and checked the tread depth yesterday. 4/32" on the rear and 6/32" for the front. Wear pattern is excellent. I was hoping they would wear better than this and my wife just retired from a job wherein she commuted over a twisty mountain road every day, so this might with have something to do with it. But I'm still left wondering why a none-heavy car like the Z4 (that in this case is not driven all that hard) consistently wears out rears faster than fronts?
Edit: Just looked up the weight distribution and it turns out it close to 50:50; in fact slightly biased towards the rear!
