My rims are 8" and you are correct on the tire size. I wheeled a bunch last Saturday at my friend's land and there were a lot of rutted out hill climbs where I was leaning hard on the passenger side (nearly flopping). It just packs dirt in the rims. I am hoping to to find another cheap set of rims to make into beadlocks. I just need to wheel one more time before I tear the whole rig down and rework the cage and suspension.
