Re: Tire size
The difference between them is on the wheels relative to diameter. The tires, themselves have the same ~30.6" diameter for the OEM sizes.
Some folks feel that the 18" wheel setup is "more comfortable" and for off-road applications it does give you a little more sidewall. Others prefer the ride of the 20" wheel combinations. It's very subjective. I'm perfectly happy with the 20" wheels, quite frankly, both for looks and ride.
