If I lived in NY and had a separate winter car, then I'd still get summer tires, but for sure I'd expect poor traction on cold tires.
Actually, the Conti DW's are a dry/wet tire (Thus the DW designation) and they're excellent in the wet...but I agree that they probably shouldn't be used in freezing or near freezing temps.
