How does the collective wisdom feel about a 12.50 inch tire on an 8 inch rim?
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.
I'm not picking my nose...I'm just pointing at my brain!!

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...
