CJGers: Yes, allmopartparts offers the best price but the fact is that you still need the sensors and the hubs. Even with the very moderate discount, you are looking at well over $4K for wheels and then you will need the large tires.
Count on getting banged for close to $5K for the privilege of switching to the 22" rims. IMO, that is about 15% or so, the value of the truck. Not a smart move unless you have real deep pockets or work for the federal government.
