Negative offset

[Rhino_HD]

I just bought a 6" lift, haven't bought wheels/tires yet. I am planning on running a 37 with 20 or 22 x12... I do not want the tires to rub, what offset do I need?

Any 12 wide you find is gonna be within 5mm of -44 offset so really no need to worry about the specifics. With a 6" you should be fine with 12's and 37's.
