    Looking to mount 33x12.5x15 BFG Mud Terrain's onto my truck. Wondering if its smarter to work with 8 or 10" wide rims.


    Some tell me that rubbing is less of an issue with 10" but i'm worried about the wide tires and only 8" of rim.


    thoughts? input?

    you would be fine with 8"... but I'd go with 10" just incase you decide to bump up the tire size later.

    The 10 inch rims won't clear on my rig. They rub the fenders. I have then for when I up size. But the 8 inch clears nicely

    re: 8in or 10in rim

    I've got 33x12.50 15 on 15x8 inch rims with a two inch lift they fit with no rubbing. My tires when at street pressure crown up in the center due to lack of rim with. I think this would wear out the center faster if i stay at the higher pressure. I saw a truck similar to mine with the same tires on a 10 in rim and the tires did not crown up in the middle, they looke evenly worn but they looked smaller on the 10 in rim. I like mine on the 8 in rim.

    hope this helps

    I hear ya about the tires flatting out and looking smaller. How much pressure do you run on the streets? I run 32 psi on the street.

    I've got 33"s and 8" rims. I think thats the way to go. If you go any wider than 12.50, than you should probably go with 10" rims.

    15x8s are fine... you can run 44s on 'em... not sure what the problem is here.
