Are the 545i sport-package front and rear wheels 8.5" and 10" wide, respectively? Thanks much.

Next questions. Are 275/35-18's too wide for 18 X 8.5 wheels? Do 18 X 10 wheels work on the rear of the 545i with 275/35-18's.

[/quote]Thanks to all above for the input. My goal is good looks and significant weight savings (both are necessary conditions). I am thinking of BBS RGR's (8's F and 10's R) and Michelin Pilot Sport PS2's. This combo yields about a 125 lb. sprung-weight equivalent weight savings--which translates into about 13 flywheel equivalent HP. I am not interested in tires higher than 18" because they would, in effect, increase the rear-end ratio numerically.And, Bokke, your wheels do look great.

[/quote]That sounds like a fantastic combination - great wheels and tires. You will notice a significant difference in the performance by saving that much unsprung weight.

Thanks much for the moral support. Are your wheels (below) Black Diamonds? I think so from some of your posts, but somehow I am not sure. They don't look very black, but they look great--whatever. Thanks.

I don't know about 275s, but I'm looking to go bigger than 245s up front as I'm due for new tires pretty soon.

Go to the link below if you are interested in what I ended up doing. The discussion is at least slightly interesting--depending on your interests.
