Not specific to bike tires, but: If you run sticky tires on a rock crawler, some of them get very slippery in the cold. As far as I understand, the stickiness and slow rebound qualities of the rubber are because there are almost closed cells in the rubber to make it less dense and confirm better to the terrain. These voids closer to the surface that become open can get water trapped in them when it gets wet or freezes (think like a sponge). The thing on a rock crawler is you can dry the rubber, or at least warm it with wheelspin. Most cyclists aren't capable of that.
