backspacing for 37's

I have seen many users on this site have 37's with a 6" lift or even less, but I can figure out how. I have 35x13.5 on my truck and it rubs the radius arm at full turn. I'm guessing its my backspacing, so I'm wondering what width wheels and backspacing you guys are using to fit your 37's?

I run 17x9's with 5" bs and 37" Hankooks and I have no clearance issues with a 4" lift.

I ran 37s on a 20x10 w 6" lift and would get some rub all full lock. if you run a 37 on a stock wheel you could probably get by with a 4.5" lift. Your right it comes down to the backspacing. I don't have my old wheels anymore and dont recall the BS, i think was 4.5. Not i run 20x12 rockstars and running 40's on 10 lift and i tear my fenderwells up if im not careful. I really need another 1" of lift.
