Winter tires, and all season tyres, are constructed with a different type of rubber compound – containing a higher percentage of silica and natural rubber. This allows winter tyres to remain flexible and perform better in lower temperatures.
Winter tires are specifically designed to provide traction in deeper snow and in sub-zero temperatures. Mud and snow tires will perform just fine in lighter snow but, if you regularly drive in snowy conditions at temperatures lower than 7°C, you’re better off with a set of good winter tires. In other words, if you wouldn’t feel comfortable choosing an all-season tire in the winter, mud and snow tires are probably not the best choice for your vehicle.
