Re: Wheel/Tire question..
First, the 20" Forteras are very smooth and quiet.
Whether you go 17", 18", or 20", they all need to have the same diameter so as not to change the speedometer readings and therefore the amount of wheel well showing will be the same. The only way to fix that is to lower the vehicle and that also means giving up Quadra-Lift and going with a fixed suspension. That will also give a stiffer ride unfortunately.
