I have found a set of 18" style 107 wheels, with tires. I'm wondering if they'll fit my E90 (non-sport). The seller did not know the offset, but did say the fronts tires are 225/18/40 the rear are 255/18/35. If I knew the offsets, I could probably figure it out.
I asked some questions about another BMW wheel style on the e90 forum and was pointed to this link. It has pictures of almost every BMW wheel style and specs for most of them. The style 107 wheels are 18x8 front with et47 offset and 18x8.5 rear with et 50 offset. You'd need 12mm spacers to get close to the offset of an e90.
