I drive on unplowed paved roads and I can tell you from first hand experience that there is a world of difference between snow tires and all season tires. The chemistry of the tire itself is different. All season tires start getting hard around 40F whereas snow tires stay soft/rubbery below 40F and colder. This is fundamentally why snow tires are superior for snowy/icy conditions. This is also why you should not use snow tires in summer because they will wear very fast due to the composition being soft.
