well found this after looking the e90
19's
18's
not the best angles and not 100% sure on sizes but after eyeing it and comparing you can def. see the size diff, esp in tire.
Also went thru some of the posts and one guy def has 19s and one guy may have 18s he was going back and forth b/w the two
either way the 18s are def not as concave on the APW
much more concave on the silver but again bad angles to determine this
