wheel backspacing?

[MTChevy]

Im looking at new wheels im getting ready to order. Its an 8 inch wide rim i am planning to fit 33x12.50's on. My question is i have two choices. Do i want 3 3/4 inch backspace or 4 3/4 backspace? thanks

less backspaceing will make your wheel stick out farther you might want to stack with 4 3/4 back spaceing if you arent running any lift.

its going to be on a 4 inch lift. 3 3/4 what I want then?
