My winter rims and tires arrived today. I didn't like the look of the rims in the tirerack package, so I put my own setup together at a comparable price. The rims are Beyern Mesh. They look better than the Sport Edition wheels IMO.
18x8.5; ET30; 24lbs
18x9.5; ET30; 26lbs
Tires are PA2s:
235/40/18
255/40/18; 25.75lbs
The rear offset is off by 7mm. I think that'll be fine. If I don't like that, I'll use a 10mm spacer, but I really don't think that'll be an issue with a winter setup. I'll put them on this weekend and post some pics.
