If it's just that tire, it may be a crappy tire. Manufacturing defect. The way you say "horrible struggle" putting the tire on makes me think there is some kind of compatibility issue. 60-80psi seems low, too. Why the need to have a trainer-specific tire? Seems like it's a PITA to install anyway. My trainer's roller is not metal, so it's very gentle on the tires. Does this one have a metal roller, and is the wear you get on it worth the added struggle of switching to this trainer tire which is giving you trouble?
