I was goofing around today and tried a couple of different wheels on my car.
I have seen some discussion on using BMW wheels, so tried on one of the summer wheels from my 330i. Wheels are 18x8.5 w/ 235-40-18 tires (only a little over 25" tall). Backspacing is about 5.5" and it fit well in the rear and could have been 2 inches wider with this backspacing. The 120mm bolt circle fit with no problem.
