Unicyclists often over-inflate the tire for freestyle and regular riding. With a good rim the tire can handle being over-inflated. The Torker LX has a good rim with a good hook to hold the bead of the tire. You're not going to blow the tire off the rim by going up to 80 psi.
With a good rim it is not unreasonable to go 50% over the max recommended pressure for the tire. Some people even go higher.
When going up to higher pressures you do need to make sure that the tire is properly seated in the rim. The bead of the tire should be even all the way around the rim. If the bead isn't even all the way around the rim you need to deflate the tire, push things around to make them even, and then reinflate.
