A winter tire is specifically designed for cold weather conditions, typically when temperatures drop below 7°C (45°F). These tires feature a unique rubber compound that remains flexible in low temperatures, providing better traction on icy and snowy roads. The tread patterns are also optimized to channel snow and slush, enhancing grip and stability. Using winter tires can significantly improve vehicle safety during the winter months. They are equipped with deeper grooves and more biting edges compared to all-season tires, which helps prevent slipping and skidding. For optimal performance, it's recommended to install winter tires before the first snowfall.
