how much backspacing do I need?

hey guys!

Im ready to buy my wheels and tires. But I have no idea what backspacing to get.
I want to use my stock fenders with 33 x 12.5 M/T tires. I also have an RE 5.5 lift.
I dont want the tires to stick out too far, maybe like an inch or two. Do u guys have any idea what the backspacing should be? Or maybe just give me some info on what u guys are running to give me an idea of what I need. Thanx!

3.75 is usually standard. i am running 4

3.75-4.5 will probably do you right.

what he said ^

4.5 MIGHT rub depending on what control arms your using....4" should be about perfect for most setups.
