Since this new job in Edmonton is easy cycling distance, I dusted off the bike for the summer and really enjoyed biking back and forth. With winter coming I remembered that old student experience and (as noted in the winter tire thread) thought I'd try winter biking again.
Went for purpose-made tires this time, carbide teeth set in aluminum inserts:


So far so good, ice and hard packed snow are a piece of cake, had a minivan take a blind alley corner at speed and I could brake hard enough on ice the rear wheel lifted off the ground. Heavy fresh snow is a pain on the other hand, lots of fishtailing. The studs grip fine but the tire doesn't cut through the snow any better. But it packed down pretty good after a day so not a big problem.
At the moment am looking forward to a winter of cycling!
