I've heard allot about tramling on the OE 235x4 setup and wonder why BMW changed to 225/45 and 245/40 on post '95 cars. Was this to reduce the tendancy of the car to "follow" every rut in the road or did it have more to do with oversteer? I have all 7.5x17's and need new tires. I was thinking of a staggered setup like 215/45 in front and 235/40 in rear. Any comments or experiences? Should I try this setup or will a good tire the OE size suffice?
Thanks!



I would stay with the same size on all four corners. The wider tire in the rear increases understeer. The 235/40R17 also needs a 17X8 wheel. I would say run 225/45R17 all the way around. If I can help let me know. Thank you
