Kevin,
Ive got 31 10 50 / 15in on 8in rims , Ive had 32 11 50 on it . I am pretty sure you will have to go to 10 in rims ? Some of the others may know for sure , you might give a tire shop a call too and see what they think ?

I've run 31.00 x 11.00 x 15's on stock 7" rims so you should be able to run 12.50's on 8's. You're going to have serious sidewall bow so to get a flat tread pattern you're going to have to run lower tire pressure. I would do this by laying my driver's license on the ground and deflating the tire until I could no longer get the license to slide under the tread. It seems to me I ended up running 22 psi. The other problem I ran into is the rear inside lugs used to hit the frame when turning lock-to-lock, so just don't turn so tight. You asked if it could be done and the answer is YES. However, I still don't recomend it. You're better off going to 10" wheels.

I've got 12.50s on 8" rims on my J**p with no broblems. A BFGoodrich dealer can look it up in the catalog(I used to have a copy of the page but I cant find it). I think the reccomended rim width for a 35 12.50 is 9-11 inches.
