I just mounted my BFG KO2 285/75/16 on my dually wheels. I put them on the truck with no lift and they fill the wheel wells good with no rubbing. The tires on the rear do need a spacer but a 2" spacer is more than adequate. The bulge of the tire is only maybe a 1/4 past the wheel mounting surface on the stock wheels, so figure you want atleast an inch between the two when mounted on the ground so a 1.5" would work but a 2" is good if you just want the peace of mind and a little wider stance.

Just a heads up for guys wanting some wider tires on there dually.
 
Well no one could give me a positive answer on if 285's would fit so I only bought and mounted two lol I'll post an updated pic when I get the other four
 
tell ya from past info on these trucks .

255/85/16 just clean no spacer but if heavy load = rubbing .

and on narrow c&c drw it will possibly rub leafs if wider is used .
 
c&c narrow is for flatbed / utility box / all that stuff.

wide is pickup box with bolt on fender flairs from factory .
 
Ohh well you learn something new everyday, hey are those the trucks that run a single wheel bed and still kinda manage to tuck most the tire under the truck? I always thought all those were just custom narrowed axles lol
 
no the SLEEPER drw setup is a narrow c&c rear under the truck and little rubber flair flap for the tire stick out .
