Type 820 on a 330i zsp

I found these on ebay:


Specs say: size - 18x8.5; offset +20 & +38; bolt pattern: 5-120

Now the listing says it will fit all 3 series from 1992-2006, but I think i trust people on here better. I really don't understand the whole definition of "offset". So if someone could explain that to me that would help. Also can you put non-staggered wheels on the 330i with sports?

Thanks.

I'll guess the +38mm offset for those on the E90.

Use the calculator at the top of this page to see how much a given offset moves the wheel in or out, and clearance w/ the strut.

The way I understand it, offset is the position of the center of the wheel relative to the mounting surface on the hub. Offset can be positive or negative. Try this link:

Sounds like it will fit, depending on the tire you use on the rear wheel (18x8.5 + 20)

nice set of wheels

I want to buy these wheels also for my 06 325i.

What kind of tires are you going to buy. There were some American Geneneral Tires on tirerack. 225/40/18. I am probably going to get those.
