At What Temperature Should Winter Tires Be Replaced?

[GeorgeMarie]

When the average temperature drops below 4 degrees Celsius, it's time to switch to winter tires. This is because all-season tires become harder in winter, leading to reduced friction coefficients, which affects the tire's grip and wear performance. Principle of Winter Tires: The tread that contacts the road surface uses a special silica-based compound to ensure the tire remains exceptionally soft even at extremely low temperatures, providing excellent ice grip. The tread pattern typically employs cross-Z-shaped siping technology, which not only improves braking performance on snow and ice, shortening braking distances, but also delivers ideal traction. Description of Winter Tires: These are tires designed for use in snowy conditions. The rubber tires may have metal studs to enhance grip. In colder regions prone to snow accumulation, such as Russia, people use these tires during winter.
