I have a 95 M3 with the stock 17x7.5 10 double spoke rims with pirelli p7000's. I have noticed that the rears are significantly more worn down than the fronts (probabily from the numberous oversteer situations in driving schools/ autocrosses). It is starting to rain and I would like to get the front tires with more tread on back. I am wondering if rotating the wheels/tires is as easy as just moving the left front to the left rear and the right front to the right rear? Will there be any alignment or balance problems? Thanks alot.
