Are the sizes of snow tires and all-season tires the same?

[LorenzoFitz]

Snow tires and all-season tires are the same size. Advantages of snow tires: Compared to ordinary tires, snow tires use a special compound to increase friction with snow and ice surfaces. Their advantages lie in improving passability and safety on snow and ice roads. The tread material of snow tires is softer, and the carefully formulated silica-mixed rubber compound allows for tighter contact with smooth ice surfaces, generating greater friction than all-season tires, thereby significantly enhancing vehicle control and safety on slippery ice surfaces. Principle of snow tires: The tread that comes into contact with the road surface uses a special silica-containing compound to ensure the tire remains exceptionally soft even at extremely low temperatures, providing excellent ice grip. The tread pattern typically employs cross-Z siping technology, which not only improves braking performance on snow and ice, shortens braking distances, but also delivers ideal traction.
