Got the new Rancho 4" lift and 20x10 Chrome Rockstars and 305/55/20 BFG Mud Terrains put on last week. The rancho lift actually lifted the truck about 5" on the stock wheels/tires, so it's a little taller than advertised. Original plan was for 35" Nitto Trail Grapplers due to the fact that rancho says a 35" tire will "easily fit" but the backspacing options on the chrome rockstars were pretty limited, and the 35s weren't even close to fitting. Probably would have with the proper backspacing/offset though. Either way, the BFGs measure about 33.5" and I'm pretty happy with them. Still required a little fender well liner trimming and I trimmed a little off the front air dam, but I'm thinking of taking it off altogether. And if anyone wants those Nittos, they're posted in the classifieds.
