I ended up moving on to wider tires, so these are up for sale. 120TPI ultralight casing. They were used for under 50 miles on snow only, so are virtually brand new. Only real sign of use is the sealant residue. These are really great tires, a good bit bigger than something like the Hodag, and nice big knobs for great traction. Asking $140, and I'll work with the buyer to figure out the cheapest shipping option.
