2008 328xi wheel and tire upgrade?

arctic56 · 03-06-2012, 10:55 AM

Will I have any issues if I put a staggered set of wheels and tires as follows:
OEM tires are 205/55/16 328xi

225/40/18 fronts
255/35/18 rears

I have checked the Tire Rack calculator at the top of the forum and get the following results:
fronts = .0832% difference
rears = .0598% difference
speedometer had no change.

Remember, this is an xi without sport package. I have read some other threads that seem to indicate that there could be an issue with the transfer case, but want to hear from those who have actually made this up grade.
Thanks.

BMW offer those tire sizes as an option on xDrive, so you'll be fine.

I see them listed for the 2011 335xi, but not the 328xi. I realize this is engine displacement, but any difference in the overall suspension, transfer case, etc. that would make any difference? Just want to be sure that I don't screw up my car. Thanks.

You'll be fine so long as the rolling diameter is within a 1% difference for the xi / x-drive models.

I run that set up on my 2011 328i xDrive, no problem at all,
