These were 20x10 with a -12 offset, 305/50-20 tires. I had the valance cut and the pinchweld on the back of the fender cut and hammered flat to stop the rubbing.... it still would with the wheel locked. If you've leveled the truck,run 285's, and cut the valance/pinch weld, you may be able to get away with running a -44 but you're gonna get some rub no matter what.
