people are always calling different OEM BMW rims style this and style that.

is there a site where i can see all the OEM rims, along with their style numbers?

(sorry for the double post)

justin (or anyone else)... question:

I currently have these rims: LINK (http://market.autopartsfair.com/bmw-wheels_rims/catalog-item-5540.html)

I want to get these ones:LINK (http://market.autopartsfair.com/bmw-wheels_rims/catalog-item-5537.html)

my current rims are listed on that site as 47mm offset. the ones i wanna get are listed as 46mm offset. what does this mean? and can i switch?

It means the centreline of the wheel is 1mm further away from the hub. In the end, the wheel will be 1mm further away from the strut.

They are essentially identical. Even 30mm offset with that width would work, don't worrry about anything.

ohhhhh, ok... i see. so offset is the space between the hub and the rim?

so what is bolt pattern?

No. Offset is the distance from its hub mounting surface to the centerline of the wheel.

Bolt pattern is the diameter of an imaginary circle formed by the centers of the wheel lugs. And all BMW 5-lug patterns are 5x120.

so a bolt pattern has 2 numbers.

the "5" in 5x120 means 5 lugs, right?

and the 120 is what? a 120 mm diameter of the circle formed by the centers of the lugs?

and is that true for ALL 5-bolt BMW rims? including older ones, and really new ones, like E90's? if so, does that mean that all BMW 5-bolt rims will fit any BMW that takes 5-bolt wheels? so all i need to know is if the offset will fit my car?

Yes on the bolt pattern logistics questions.

And yes, all 5-lug BMWs are 5x120, right back to the 70's. The differences lie in the centrebore (the size of the hub on the cars), and offset. Offset on all 3-series (E36/E46/E90) never changed much, and neither did it on all other BMWs. The difference is that the two are completely different, and if a wheel fits one it won't fit the other. The centrebore changed more often over the years, with some cars like the E39 being larger than others. You don't need to concern yourself with that though, all of the 3-series wheels have the same bores so you will be fine. The only little note to keep in mind is that the rear E46 M3 wheels are 5-series and up offset, so avoid those.

Hope that helped, ask if you need clarification.

It's more of a sickness than anything.

no no, i like that you know your shit... just cuz i've never understood how wheel sizing works, and im very happy that you have the patience to explain it.

thanks!

i will certainly be sending you any wheel-related questions that may arise for me :D

so to clarify: E90 rims will fit on an E36?

Mystikal

Most. Some have a lower offset, so it would be a close call with the fender. I'll say that they will ALL fit, just with some you'd need narrower tires than what came mounted on the E90.

I see.

Well thanks again Mystikal. The help is much appreciated!
