1.Snow tires softer. The characteristics of rubber is it will becom hard when the temperature decreases. Snow tires are made with more flexible rubber compound that helps deliver the best road grip in snowy and icy conditions. So the snow tires’ compound remain flexible in temperatures below 45 degrees. And it can provide us high grip even though in low tempture. However the all-season tires will be harder and can’t provide enough grips in that condition. But the snow tires will wear out much faster when you using them in hot weather.
2. Snow tires has more deeper grooves and sharp irregular edges.More transverse and variety grooves can absorb water avoid form the water film. But these small rubber pattern wear out faster.This is another reason make snow tires wear out faster.
