I have a set of 15x7 bottlecaps w/tires for sale. The front tires are Bridgestone Potenza RE71-205/55/15 (VERY STICKY) that have only 3,000 miles on them, but have a little wear on the outside corners (heh heh). The rears are Sumitomo HTR50H-225/50/15 (almost as sticky as RE71, slide VERY progressively) that also have only about 3,000 miles on them and look almost brand new. The wheels are in good condition, with a little curb rash on every wheel. The centercaps are included, but a little clearcoat is peeling on two of them. This wheel/tire set is off my '85 535i. This setup will really make you car handle, as it did mine. I am upgrading to 16" wheels.
If you are interested, please e-mail me at bimmerman325@yahoo.com. Thanks.
