1, from the appearance.
Snow tires are different from ordinary or single guide tires, and have asymmetric directional tread patterns. There are many grooves in snow tires, which is the proportion of grooves on the tire surface. The higher the ratio, the better the drainage. Snow tires have at least 1000 small grooves, and ordinary tires have about 200.
2, from the material point of view
Snow tires are softer than ordinary tires, mainly because the tread adopts some special formulas. For example, the prepared silica mixture rubber formula can contact the smooth ice surface more closely, thus generating greater friction than the four-season tire, and greatly improving the handling and safety of the vehicle on the smooth ice surface. Tires will remain soft in low-temperature snow, while ordinary tires will harden with the decrease of temperature.
