I used to. More options for the 16" wheels but actually, I think its becoming a toss up on options for 15 and even 16" tires.
I have a brand new set of five american racing wheels in a 15x10 and jones for something different. However, they also have brand new 35" rubber on them so I would likely take a beating if I sold them.
I would jump to a 17" wheel if I did it again. Anything larger than that looks goofy to me...
