I know most people lift 4x4's but it's very popular in the Phoenix/Scottsdale, AZ area to put large, low profile tires on trucks and SUV's. The local dealers have them on 2wd models but not any on 4x4's yet. Just curious if anyone has had any experience and if there are any problems or advantages other than the obvious very cool look they provide. Also, anyone got a cost estimate for these type of wheels & tires??? Thanks a bunch..
