Those tiny cuts are called sipes. They work by wicking up water off the surface of ice so the rubber can actually contact the ice. Ice itself is not slippery, it is the thin layer of water on top of ice (made by the weight of tire) that makes it slippery. That is how ice skates work. Weight of the blade creates a thin layer of water.
