Last year commuted all winter on Kenda Kaliente tires. No issues. No flats. No drama. I live in Chicago. The roads are kept in pretty good condition so I tend to bike all year even while it's snowing outside.

This year, I probably won't change my tires unless I get a really good deal on a pair and even then I'm not sure it would make much of a difference. Keep your upper body loose and only make deliberate movements. I think technique is more important than the tire.
