    How much backspacing will I need for 33x12.5x15 inch tires on 15x8 rims on an '86 K5 w/ 4 inch suspension (front springs/flipped shackle) lift & half ton running gear?

    Thanks,
    John

    <font color="green"> Mine are more like 4.25. 38s on 6" lift, backspacing seems perfect to me, the tires don't stick out at all and only rub under major flex, and that's on the top edge of the fender. I can measure the backspacing again tonight just to be sure if you want. </font color>

    I am running the stock wheels with my tires, I have 33x12.50, under a 4" lift and they don't rub at all.

    I'm going to pick up some wagon wheels Tomorrow (Friday 6/28), and would like to be sure I can get them w/o having to order. My question really should have been will stock backspacing (whatever that is- I haven't measured) be o.k.? It sounds like it should be.

    Thanks,
    John

    Yes, stock backspacing, and it is 3 1/2".

    any idea how to measure the backspacing on a random rim I come across? Figured I'd post this while we are on the subject.
