Thanks! If I'am following you guys right,"Long box /Pooters"! (Backspacing) is measured from the wheel hub where it meets the hub/brake drum to the inner edge of the wheel not the tire? I pulled a wheel today and I'am about where Pooters is at 4.25. I think,but not sure these are American Racing 8 lug mags. Add to that the tire Michelin LTX M/S 235 85 R16's and I'am closer to 5.
