I've got these tires, I love them off road. They hook up great on rocks and do good in snow. They're mounted on a 15x7 rim and I blew a bead today out in the snow at about 7 psi. I had never had a problem with them on rocks at that pressure. I drive my cruiser on the street quite a bit and these are noisy and bouncy but I'm okay with that because I knew I was buying swampers.
