I have 16x10 with 0 offset 5.5" bacspacing like my stock wheels. This allowed me to run 36x15.50's on 6" full drop suspension lift with light crank and mild trimming. The problem on our trucks is that the wider the tire wheel combo sticks out the sooner it will rub on the front bumper and back edge of the fender. I had to custom order the backspacing on my wheels to keep these wide tires tucked in and not rubbing when turning. 10" wheels with 4" backspacing would start rubbing with anything wider than a 35x12.50 tire, and would stick out roughly the same as my tires do.
