Recently purchased an 02 Z3 2.5 Roadster...I need rear tires and wondered if a 275 35 18 would fit on the rear. The car has 18 x 8.5 wheels front, 18 x 9.5 rear. A couple of reasons I want to do this..one is asthetics...I like the look. The other reason is the speedometer is 3 to 4 mph fast at 30 to 70 mph. The current tire size on the rear is 255 35 18, 25 inches tall. Most of the 275 35 18 tires I have looked at are closer to 25.5 inches tall. I think the half inch in diameter would put the speedo closer to what it should be...Question is, will they fit?

Re: Tire size for rear of Z3
You came to the right place to ask. We've tested all manner of wheel and tire sizes on a Z3 (non-M) and here are some pics:
18x10" with 285/30/18 Hoosier, no spacer
Front was an 18x9" with a 255/35/18, rear was the 18x10" with 285/30/18

In short... yes, the 275 rear will fit on the rear, with the right wheel and backspacing. Probably on the stock rear wheel, too.
