    I can’t find a good guide to tell me backspacing and offset for an OBS 2dr Tahoe.

    I don’t want to put my suspension through extra stress.

    I am going to lift it 4” and want to run 33x12.50 BFG All Terrains.

    I think for a 7.5” wide wheel I need -12 offset.

    What offset & backspacing for a 9” wheel would keep me in a safe range for my suspension?

    Seems the negative -12 I’ve seen recommended for a 7.5” is offset that’s accounting for the increased tire width and the 1/2” wheel width increase.

    Do you adjust the offset as the wheels get wider?

    Thanks, these things are more complicated than the last time I lifted one and changed wheels.
