[QUOTE="IsaacVky, post: 303734, member: 12652"] You really need to do some homework, not just swapping only! Maybe it would rub the fender, what's the ET, negative or positive ET, would it rub the inner suspension, maybe M5 has more clearance for the bigger tire size, your speedometer may give different reading, out of the 3% range and such and so on! I'm also planning to change my E39 M-Sport rim to E39 M5. Did some homework first and I found, OEM 235/45/17 8J FRONT ET20 255/40/17 9J REAR ET26 E39 M5 8J ET20 FRONT 9.5J ET22 REAR In order to use this rim without having problem and accurate speedometer or at least not much differences, calculated the tire size and I should use 235/40/18 FRONT +0.3% 255 or 265/35/18 REAR -0.02% or +1% Lastly, you have big rims but with small brake rotor ..
