I've not had any luck finding someone selling a set rims so I'm looking into buying new ones. Much of what I'm finding is available only in 7 inch width. My stock rims are 6" wide in front and 7.5" wide in the rear. Is there any harm in running a 7" wide rim front and back? I know it will slightly affect the height of the tire but I don't know if it's enough to worry about. 7" rims would make the rears slightly shorter and the fronts taller but I don't know if it would cause trouble with the 4 wheel drive.
