säsongsdäcken

Säsongsdäcken is a Swedish term referring to seasonal tires, specifically tires designed for use during distinct weather conditions. In Sweden, this primarily refers to summer tires and winter tires. Summer tires are optimized for performance in warmer temperatures, providing good grip and handling on dry and wet roads. They are typically made of a harder rubber compound that does not become excessively soft in heat, which helps maintain their shape and responsiveness.

Winter tires, on the other hand, are designed for cold weather, snow, and ice. They are made from a softer rubber compound that remains flexible at low temperatures, allowing for better traction. Winter tires also feature deeper treads and a more aggressive tread pattern with sipes (small slits) that help to grip snow and ice.

The use of seasonal tires is a common practice in countries with significant temperature variations throughout the year, like Sweden. It is often legally mandated or strongly recommended to use appropriate tires for the season to ensure road safety. Driving with summer tires in winter conditions can severely compromise braking distance and control, while using winter tires in summer can lead to faster wear and reduced handling due to the softer compound. Tire changes are typically performed in spring and autumn to align with the changing weather patterns.
