I've been looking at a few magazines and I think it may be better to go up to a 17. My experience with alot of tire dealerships is that they only sell you what the manual calls for. I have a set of 22's on my wifes Chevy Tahoe and they look and ride good. But I had three different shops tell me they would'nt fit. But I'm thinking maybe the 15 inch wheel is too small.
