I loved the look of the beefy rubber I had under my 2001 BMW Z3. It used 17" x 7.5 on the front and 17" x 8.5 on the rear. Has anyone tried putting offset sized wheels on the rear to allow for a wider tire? I'd like to get a 245/40 17 on the rear end. Not sure if it would fit under the car. I'm fine with the stock size on the front end.
