A quick question here. How long does a michelin pilot sport rib (rears) last. The ones on mine have about 3500 miles on them and they are already down to about 50% or maybe a little more. Is this normal with lost of around the city spirited driving? Also this place has a lots pot hole and most or the roads aren't that good. I have the 17" wheels on my boxster base. the fronts look brand new !!!!!!!

As they say.....YMMV. This question is asked so many times but two major factors OE just covered....1)tire pressure and 2)driving style.

Normally on street tires you will go through 2-3 sets of rears to every 1 set up front.

I was just worried of it being somekinda allignment issue. I knew that these things eat rubber !!!!!!! (especially if one like the curves ). But just wanted to make sure that it was not an allignment issue. The wear on both the rears look to be uniform. I was really suprised because I dont track this thing and still the tires lasted me only 3500 miles. Seem'd awfully low.

Also I am running at 30 in the fronts and 36 on the rear. Maybe I should reduce the pressure on the rear and see what happens
