Going to buy wheels "need help on WHEEL OFFSETS"

[juan525i]

I have a 92 525i, iwant to buy 18" wheels but i need to know what is the maximum offset i can use to achieve the most deep dish apperance i can get. The rims I want are the DIABLO VIENNA 18", 7.5" wide. I know the offset in my car is 20mm but can I use a smaller offset like 15mm or 13mm to achivev what i want, please help me out on deciding on the best offset and the appropiate tire width for my 7.5" wide Diablo rim. Also will a 15mm or 13mm offset rim show a difference from a 20mm rim, will i see the difference or is it too small to differ.

15mm for 7.5" wide rim is fine for E34

I know we've discussed wheel offsets a dozen times, but I might as well tack it on the end of the newest one:

I'm looking at a set of 18x8s with (I think) a standard 20mm offset. Will that fit inside the well?

a 245/40x18 tire mounted on 18" wheel 13mm offset fits just fine; no rubbing.

18" with 20mm offset is the OEM spec for the e34 M-parallel wheel.
fits perfectly in the well.

Super, thanks Mike!

The offset varies only because of the width... for 7" or 7.5" width, we can go between 15mm to 20mm... other width is different.

What would be the best tire for my 7.5" 15mm offset rims, 225 or 235's
