Kesärenkaat

Kesärenkaat are tires specifically designed for use during the warmer months of the year. In many countries with distinct seasons, like Finland, the use of specialized summer tires is common and often legally mandated. These tires are constructed with a rubber compound that remains firm in higher temperatures, providing optimal grip and handling on dry and wet asphalt.

The tread pattern of kesärenkaat typically features larger blocks and fewer sipes (small slits) compared to winter tires. This design enhances road contact for better traction and stability during acceleration, braking, and cornering. The wider grooves also help to efficiently evacuate water, reducing the risk of aquaplaning on wet surfaces.

Using kesärenkaat in cold weather, especially when temperatures drop below 7 degrees Celsius, is not recommended. The rubber compound hardens in the cold, significantly reducing grip and increasing braking distances, which can be dangerous. Therefore, it is essential to switch to winter tires once the ambient temperature consistently falls below this threshold. The transition from winter to summer tires is typically done in the spring when temperatures begin to rise. This seasonal tire change ensures both safety and optimal tire performance throughout the year.
