    hey guys and gals
    im running 35s on 18x10 and they rub a little on the body mount and was wondering. what backspacing i need to fix this problem? i have no clue on what the backspacing is now. the tire shop told me to go with a 8" or 9" width. but they couldnt tell me on what backspacing to use.

    thanks

    Im guessing you have too much positive offset. What is your offset?

    flip over the tire and lay it flat on ground upside down. lay a board or
    ruler across the rim and measure the distance b/w the bottom side of
    board and where the tire mounts to the truck. that is your backspacing.
