    Minimum lift for 33\" tires

    Do you need a lift to run 33" tires without rubbing?
    If so whats the minimum

    Re: Minimum lift for 33\" tires

    I'm running 33-12.50 - 15's with no lift. They are mounted on 8" rims -- it is my understanding if mounted on 10" rims they would stick out and hit the front of the front wheel wells.

    No rubs - but then again, about the only off roading I do is my long dirt driveway.

    a couple of pics here:

    it depends on the backspacing of the rim if you keep the tires inside the fenders you can do it with no lift if the stick out past the edge of the fenders they will rub thats how i have 38's on mine with only 2.5in lift and trimming /forums/images/graemlins/eek.gif /forums/images/graemlins/thumb.gif

    Re: Minimum lift for 33\" tires

    Mudhog, Could you elaborate on what size rims, backspacing, tires you have and how much "trimming" you had to do? It looks like you get a ton of flex! Also, what springs are you running? And on the rear do you have a 2.5" shackle flip or blocks or springs?? Do you think you would have to have done any trimming if you had the ORD 1" body lift?

    TIA, Brady

    Stock rims w/ no backspacing? Wouldn't they be all backspacing? I think stock rims have about 5" of backspacing, if not they'd stick out about 7". That would put the rim out an 1" further than my 15x10s w/ 4" of backspacing.

    I'm running 33" with no lift, but my susp. is not exactly flexible. I think 2" or so would give enough room to do some moderate flexing.

    I have 33x12.50s on stock steel 8x16.5s and a 4" lift (4" front springs and a shackle flip). My 33's just clear at full flex. I don't usually air down past 20 PSI though.
