Have a chance to pick up the following setup for my 2011 E92 335 xi M-Sport and was wondering if anyone knows if they will fit or cause any problems with xDrive.

M5 Replica Rims
18" x 8.5" ET38 Front
18" x 8.5" ET15 Rear

Hankook Icebear W300
235/40/18 Front
245/40/18 Rear

Thanks for the input!

You need to change the rear tyre to 235/40/18. The current setup has too much diameter difference(1.2%). It's recommended that you stay under 1% with xdrive. Wheel specs are fine.

This.

Also, 245/40/18 rubbed when I ran 18x8.5 ET30. 235/40/18 might be short enough that you will be able to get away with it with your proposed rear offset though.

Definitely don't stagger the tires like that.
