    Are you trying to find what size lugs you have or the torque pattern?

    Copy down the tag info from the axle. Then try e-trailer.com for lug pattern info. If they're Dexter axles, give them a call or go online.

    "they could not tell me what size they are"

    What info is on the sidewall of the tires?

    Have you tried this: Wheel Bolt pattern

    You'll need the measurement from center to center of two adjacent lugs. If that website doesn't work try searching for lug bolt pattern.

    That WILL NOT have anything to do with the lug pattern...


    OP -
    Go online to Forrest River, get contact info from there...have your vin# available..

    Geeze, Louise people. It's not like trailer axles went metric, or anything. 8 lug are 8x6.5".

    For those who are mystified about lug pattern, he is looking for a replacement rim and you need to match the lug bolt pattern between the old and new rims.

    I think the only other variation is the stud size, either 9/16" or 5/8".
