    It depends on how worn your front springs are and if they are the heavy duty spring option. But a 32x11.5-15 on a 15x8 wheel with around 4" backspacing should fit fine. I had that combo on a '79 2wd Blazer.

    A 33x12.5 can fit on a 2 wheeler with heavier (taller) springs, but that would be real iffy on a 1/2 ton I would think.
