I've currently got a fixie road bike with some stock road tires. They're fairly low-profile, as in, they aren't knobby, and have low-profile treads.
Because my fork and stays have enough clearance for it, I'm debating using some CX tires at least early in the winter, before riding becomes nigh impossible altogether.
The two biggest environmental hazards I'd be trying to work around would be the cold (I want to try and stay on the bike down to about -10 or -15 ºC) and slush, which is extremely abundant where I am even fairly early on in the season.
I'm not looking to avoid ice; at that point I'll probably look for another means of transportation.
Are CX tires generally alright for winter riding? What road conditions would limit their effectiveness?
