What is the correct back spacing for some 16x10 wheels for this truck.
Offset: -24mm, Backspace: 4 1/2" the first two rims
or
Offset: -30mm, Backspace: 4 1/4"

factory backspacing is 4" on a 8" wheel or (zero offset)

With a 10" wheel that will make it so there is 1/2" more on the brake side and 1.5" one the face side.  It should work.  I am running Hummer wheels on mine and they are 17x 9.5.
