Out back the wheel and tire set up is a 315/60/15 on a 15x12 with 7" back space.
Suspension is leaf springs moved inboard with mini tub. 2-2.5" lowering blocks. Since mine is pretty low in the back I still get rubbing on big bumps and cornering. A larger backspace would of been better. 7.5 is what I'm going with next. Also because it's lower, the factory split wheels tubs (mini tubbed) isn't quite enough for hight and sometimes rubs at the top. I'm gonna remove the factory tubs and use full tubs.
