correct me if i'm wrong but the 285/75R16s aren't quite even a 33 inch tire. if you're bumping up your height by 2 inches you should be able to clear 35's no problem, but i would keep in mind your gear ratio, engine size, towing needs, etc. before slapping big rubber on. i have 32.75 inch tires on my truck and i wouldn't want any larger without gears or a supercharger or something of the sort. the 285's will look sweet with a stock ride height or your torsion bars cranked.
