I just changed all 4 of my tires today, I went with the Bridgestone S-03s (Love Them). These are the second set of S-03s ive had on two different sized rims and love them even though they are not Porsche approved. I think they are far better than any tire Porsche recommends and so does Wheel Enchancements.
I have 18X8.5 in the fronts and had 225/40/18 (Stock size for the boxster 18s) put on. In the rears I have 18X10 and finally made the move to a 285/30/18 and they fit FINE... I got real excited when the guys at Wheel Enchancements said they would fit. Just wanted to let you guys know that it IS possible to squeeze a 285/30 in your rears with a 10" wheel.
***I have no spacers on my car and the rear wheel offset is 48mm (same as the stock 17s)***
