IMO 33's look good with a 6 inch lift as long as the tires are 12.5 wide or bigger and you got some decent negative offset on your wheels, the worst is when you got a big lift and the tires are so tucked in it looks like its on stilts.
^^ yep I saw a f250 with an 8" lift, stock wheels and some 33s and it looked like it was sittin on stilts.. looked retarded
