    How does the collective wisdom feel about a 12.50 inch tire on an 8 inch rim?

    No problem...

    I have a set of 12.5's on some 6.75" rims...they have near 35,000 miles on them with good even wear.

    I ran 35x12.50 on 8" rims for years with no probs. I even ran my 35x15.50 Swampers on them for a while. Looked stupid but no probs. Of course I wasnt very extreme with them.

    Rene is rogth no problem. I run 35x12.5 on 9" wide wheels. My buddy runs 33x12.50 on 7" wide wheels. You just have to keep the pressure a little lower so it doesnt wear out the center of the tires.

    I ran 33 X 12.5 X 15's on 7 inch rims for about a year. Got tired of constantly adjusting the air pressure to keep the center of the tire wearing out.
    Then ran the same sized tires on 8 inch rims for 3 years without a single problem.
    My next rims will be 10 inchers but that just because I want them. I'm sure that I could run 35 X 12.5 X 15's on 8 inch rims with no problem, seen it done. It didn't quite look right, but it worked on the street and light off-roading.
    So go ahead, run the 12.5 wide tires on an 8 inch rim, and have a great time doing it.

    David, I have run 35's on stock Ralley wheels which were 8" wide, many times.

    Look on my webshots.com site and view the Blazer pics. Those are 35's on 8's. [​IMG]

    They fit great on a 15x8. Stay on better than with 15x10 when aired down. They don't work as well on the 15x7 and it is hard to mount them on the 7.

    Keep the presures a little lower so that the don't crown out on the tread but I think a 12.50 on an 8 or 9 inch wheel looks better than on a 10 or 11, just my opinion.



    Thanks, (in advance)

    I had 16.50" wide tires on 10" wide rims and never had a problem so you won't with that combo...
