I bought a set of OEM 437M wheels for my 2011 535i XDrive M Sport. I was planning to use 245/40-19s on the front and 275/35-19 on the rear. The 285/35-19 is .3" taller than the 275 and .1" taller than the 245/40-19. All within way less than 1% difference in diameter.
I just realized the stock wheel is 8.5" wide and the front 437M wheels is 9". Now I am concerned that the tire meant for my old wheels will look stretched. I absolutely hate that look and there is nothing there to protect the wheel should you get too close to a curb.
I am now considering using a 255/40-19 to compensate for the wider wheel but I am concerned that it might rub. Is anyone using the 437M 9 X 19 with the 255/40-19 on the front of a F10? The 255/40-19 is .1 taller than the 285/35-19.
I have used the stock M5 166 wheel before with no trouble but the offset is different. The 166 wheel is 8.5" wide with an offset of 12, whereas the 437M is 9" with 29 offset which should give me more inside clearance. With the 166 wheel a 245/40 is as wide as you can go without rubbing.
Any help would be most appreciated.
