I am running OEM Pirelli P-Zeros on my '01 S, with 17-inch wheels. I did 2500 crazy miles in Europe when I got it, and after that did another 6500 miles in two summers of wild miles on the twisties of the upstate NY Adirondack roads. I just finished a 4000 mile road trip, half interstate slabs, half backroads, plus some sliding around on the Deal's Gap "Dragon" (Eastern Tennessee's route 129 through the Smokies into NC).
I have been experiencing (during the road trip) a little wobble at 75mph-plus, and my rears look shot, at 12500 miles. Tire pressure has been maintained at or maybe 1 to 2 psi higher than the recommended 29/36.
With this kind of history, is this what I should expect for tire life on my rears?
