Not a good fit a 8in wheel is to narrow and will cause the sidewalls to bulg out alot witch can effect your handling (Tire roll) also the center of the tire will ware out very fast becuse as you push the beads together the tread will also bulg upward I would get at least a 10 in wheel
I have run 38.5-14 TSL SXs on 8" wheels. It worked great! I could run around 5 psi without worring about losing a bead. It did look funny but it was on a trail only rig.
