I have 5+2's on mine with 10x28x14's all the way around. No rubbing with stock suspension and none after installing 814 shocks. I ran with no spacers for a couple of months but recently added the 1" spacers to the rear. If you don't want to spend time grinding down the ends of the wheel studs and lug nuts, go with the RB3 Offroad spacers. they're just a little over 1" so you don't have to do the grinding. I'm running System3 350 tires.
