I know there is many topics on backspacing and tire sizes throughout this, but I cannot find a straight answer to what I need. I currently have a set of 33x12.5 BFG AT KOs with some aluminum wheels I don't know the backspacing on, but they stick out quite a bit. I have a 3" lift and Shrock bumper. They rub very badly when I turn more than 1 whole turn, and if I hit a bump, forget it. I wanted to get some black steel wheels that would rub the least and wouldn't be sucky when I wheeled. I was thinking about going with a 4.75" backspacing but I really have no clue what would be the best answer. If someone could please help me with the best backspacing for the tires I would be super happy, I am tired of the rubbin'!

Thanks!
