Anybody have any experience running larger width rear tires on a M Roadster? I have to change my current rear tires (which are the 245/40/17 stock size), but I've heard that you can go with a wider tire on the stock rims as there is extra room. I've looked on mz3.net as well as the roadfly board and seems like some people run 255/40/17 with no problems (some even look like they try to run 265/40/17!).
My primary goal is to increase grip and handling - I'm not after looks. If anyone runs with 255's, have you found that handling is better? Also note that I'm not planning on changing the fronts (leaving them stock) - do you think increasing the rears but leaving the fronts alone will adversely affect handling?
P.S. I'm budget conscious, so the tires I'm currently considering are:
Kumho Ecsta MX
Yokohama AVS ES100
Bridgestone Fuzion (new for 2004 - .Bridgestone Fuzion
