for 18's stick with 225/45/18, you MIGHT be able to pull off a 235/40 with it but you'd need a lil fender rollin!

what year is ur car? is it an E36 or E46? is it lowered? if it's not lowered u should have no problems then.
here to give u and idea, with ur current tires when it says 100km/h on ur speedo it is 100 km/h. but once u change ur tires ur speedo is going to be off as well.
235/40/17 = 100 km/h
215/45/18 = 105 km/h
225/45/18 = 106.5 km/h
235/45/18 = 108 km/h
215/40/18 = 101.5 km/h
225/40/18 = 103 km/h
235/40/18 = 104 km/h
215/35/18 = 98 km/h
225/35/18 = 99 km/h
235/35/18 = 100 km/h

225/40/18 is actually the recommended tire size for 18 for e36. It also depends on how wide the rims are, if they are 18X8.5 you can go with 245/35/18 in the rear, you may have to roll the fenders though. If you have an e46, you can go 235/40/18 all around.

my rims are 18x8.5 and I used to have 225/40/18 tires, then my car got impounded for too low (4 1/4 inch drop, lots of rubbing) Now i got 215/35/18 and there is no rubbing at all. If you are not going to go more than 2.5 inch drop 225/40/18 won't rub at all.
