My Extreme 294s were the biggest PITA to mount, I wouldn't even consider fixing a flat out in the cold. I would just push it to a bus stop and catch a bus. I don't know if all of the Extreme 294 tires are like this, but my tires have extremely tight bead fit. Even with tire levers I can barely get them on. The last couple of inches of bead nearly break my tire levers when prying the bead onto the rim.
