If I want to run 285/75 on 16x8 what backspacing would I need?

I'm gonna say at least a 4" backspacing. I,ve done it with a 3 5/8 but a little close for comfort without a lift.

I went with 4 5/8 on my 2002. Worked good.

4-5/8 is stock. Most lifts spec 4-1/2.

Do we have 8 on 170 or 8 on 6.5?

8 on 6.5. The 8 on 170 is the Ford pattern.

I have 16x8 wheels w/4.250" backspacing and 265/75's. I would go with at least 4.500" backspacing as my wheel/tire combination sticks out a little farther than I would like in the front. I have been considering some aftermarket flares for a little more coverage, but I would like to see them so I can measure them prior to buying.
