I am not a wheel and tire expert so forgive me if this question has been asked before. I am looking at some Beyern Munich rims for my 08 335. The seller has them in 18 x 9.5 front and 19 x 9.5 rears. Would this arrangement fit the rears without problem and do you see any issue in having a larger rear tire than front?

Thx

Fitment would depend on the wheel's offset.

Are you xdrive? If so, you need the correct tire size to make sure the front and rear wheel diameter(wheel+tires) are within 1-2% difference. Other than that, the only other issues i can think of are tire rotations and the weird look.

Usually people have smaller diameter wheels and taller sidewalls on the rears of RWD cars for traction.

Using different diameters front and rear is not OEM on any BMW that I have seen, and 9.5" on the front will likely require fender rolling. What is the ET of these wheels?

You can check the range of what BMW is using here:

You can check the range of what TireRack recommends specifically for your car, which is a little broader than what BMW recommends, at tirerack.com. Some members have gone a little past these, but if you use BMW and TireRack, you probably will avoid the largest problems.
