I tried CX tires one winter, and they wiggliness drove me crazy. But I was living in suburban New Jersey, where there are only patches of snow here and there. Snow tires are probably not a good idea. Now I'm in New York City, and the climate is the same. We get some serious patches of slush here, and I don't think there's much we can do to improve traction on that. If I decide to brave the weather more this winter than last winter, I might lower my saddle and wear boots instead of cleats so I can put my foot down quickly.
