    This will pertain mostly to the 04-08s and I'll update as I learn new information.


    Stock rim sizes are 17", 18" and 20" You can't fit 16s because of the brakes.

    Stock widths are 7.5" for the 17" and 18" and 8.5" for 20s

    Stock backspacing is 5.5"

    Bolt pattern is 6x135mm except for the 7-lug HD package which is 7x150mm

    2wd with factory rims
    Can fit up to a 31x12.5 tire stock, 33x12.5 tire with a 2.5" level kit

    4wd with factory rims
    Can fit up to a 33x12.5 tire stock, 35x12.5 tire with a 2.5" level kit

    Backspacing:
    Follow these guidelines for fitting 33+ tires with aftermarket rims

    -For an 8" wide wheel the backspacing is 5.5 inches.
    -For and 8.5" wide wheel the backspacing needed is 5-6 inches.
    -For an 9" wide wheel the backspacing is 4.5-5.5 inches.

    Running the max tire (33 or 35) may require trimming the front valance and/or fender splash guards.
    Also, Mud Terrain/Aggressive tires may rub more than All-Terrain/Street tires because of the oversize lugs.

    Here's a picture of 295/70R17 on stock rims. It comes out to be about 33.3"x11.6". Stuck out about one inch.
