I just called up my friendly neighborhood BMW parts guy. He looked up my car and said, yes, 335. However, it didn't specify uniform or not.

He said that for the 35d, it showed two configs: 9" 335 uniform, or, with a "sport package" or an "M package" (M is non-US only), a staggered set.

I said, dude, I have a sport package (Sport package is a sub header of the ZAP on the 35d). He said: Hmmmm...

[He did actually say to use the tire size to gauge the rim width: 255=9", 315=10" -- his 'easy' method].

Perhaps its Supposed to have 10" rears and they didn't have any when they built my car so they stuck on 9"ers? Perhaps the person who is supposed to pay attention to 335 uniform and 335 staggered isn't actually paying attention? Perhaps 335 staggered is non-US only?

I think I'll talk to my CA about it. Couldn't hurt.
