18" M3 Wheels on 99 323i

Xeus · 10-26-2011, 01:34 PM

I have a 1999 BMW 323i. Stock suspension, not lowered or anything. I bought 8JX18 ET:47 and rears 9JX18 ET:26, they came wrapped in Continental ExtremeContact DWS 225/45ZR18 91Y BSW and 255/40ZR18 99Y XL B. Rear tires have some fender rubbing when cornering and on bumps. Fronts are just fine. I wanted to trade fronts with rears from the forum but failed on a couple of attempts. I decided to keep the wheels and I need to fix this problem. I am gonna roll the fenders Saturday but what if it wont be enough. I have seen people put 235/35/18 on the rears. Would anyone recommend the tire size? Need help. Thanks.

The tires are too tall and the rear offsets are too aggressive for your car.

You need to run 225/40R18 on the front and 245/35R18 on the rear.
