I'm running 285's (BFG AT KO's) on the stock rims. Had some rubbing issues at full lock and on some trails with only low profile bumpstops and 25MM Sway Away t-bars slightly cranked. Not much of an issue around town but definitely noticeable on the trail. I never hammered the pinch weld down.

I added some 1" SDORI ball joint spacers, machined down from 1.5", and no more rubbing. To level out the rear, I added Airlift Airbags. They can add potentially up to 3" of lift in the rear but I added them primarily to handle the weight of my Four Wheel Camper.
