The backspacing is around 4.5". I personally think that the 7" wide wheelis a bit narrow for the 315/75 though.

Yes I did run 315/75 on 16x8's with 4.5" of backspacing and a 3" lift.

I only rubbed a tiny bit onteh control arms. Enough to make some noise but didn't cause any steering feedback or performance problems or damage. Never rubbed the fenders except with really stuffing it with the swaybar off.

BKAST,

I wouldn't recommend mounting 315/75/16 (35/12.50/16 equivalent)tires on a 16x7 wheel. You're going to get uneven wear on the tires as well as risking tire failure! The minimum width wheel to run a 12.50" tire should be at least 8", and even that is pushing it!!
