Speaking of wheels, I'm starting to find the 17's that come stock on the CX-5 GS a little small. I realize they contribute to a better ride, than say, 19's, but it's not like the '19's that come with the GT and Signature have tiny little rubber bands of sidewall - they still have a half decent amount of sidewall.
I think I'm going to look for a used set of 19" CX-5 rims, then buy a new set of All-Seasons to wrap them with. I'll use the existing 17's as my winter wheels, and wrap them in Blizzaks in the fall.
