You need to be careful with E31 wheels... the fronts are generally et10-et13, putting the wheels further outward. They will work but will alter the suspension geometry and widths 235mm or greater may rub at full steering wheel lock.I run 235/45/17
However I have 8.5 in wide 13mm or 15mm offset wheels(17x8) and i dont have any rubing and i havent noticed any untoward handling issues,apart from a recent return of the shimmy,which may or may not be related to the more outward postion of the wheels.
