Can I fit a 35X12.50R16 on a 16x8 wheel without rubbing?

315/75R16 is a tire size very close to 35x12.5R16 (sometimes even equivalent) that works well on 16x8 rims. You will need roughly 3.75" of backspacing. A Moab factory rim with a 1.25" spacer will net you that backspacing.

You will also want 4+ inches of lift, ideally 5-5.5".
