Joel/AK, I have a good set of 20" wheels but have only run 35"s on them, when I aired them down they looked like Band-Aids, and had almost no side wall, not a good tire for here.
thumbcocker, Narrow tires are like pizza cutters in this dry deep sugar sand, they just don't work very well.

Trust me I was hesitant also running 20's aired down to 12 psi. My wife tried her damnedest to break the bead. They held up.
