backspacing recommendation

I'm looking at a terra flex 3" lift with 315/70 r17 wrangler duratrac tires. I want my tires to stick out no more than an inch from fender wells. What backspacing would I need. Um thinking 4.5

4.5 is recommended but 5.2 is common with AEV. Either will work.

The factory Mopar wheels, that are recommended for larger tires, have a 4.6 backspacing. (This is just a FYI).

For 315s, I would go with a 8.5" wide wheel, with a 4.5 BS, -6 offset, which will give your the wide stance, that you are looking for, plus they will perform well........
