i run 15x10s and have never had a problem, i used to have a set of 15x8s but they rounded the tire to much for road use,,, i had them at 8psi and they were still riding on the center tread... :shaking: on 38.5x14.50s ,, the 10s let the tread wear more evenly, but in your case the 8" might work perfect for a 13.50 size tire....

ran those exact tires on a 8 inch rim. I could play all day in the snow at 4lbs. (no beadlocks) on the rocks in the summer I would keep them at about 6-7lbs.
