Winter Tire Knowledge
Winter tires, designed for superior traction in snow and ice, were pioneered by Finnish company Nokian Tyres in 1934 with the "Kelirengas" for trucks, following with passenger models in 1936. Engineered with softer rubber compounds and deep, biting treads, these tires provide essential safety at temperatures below 7°C (45°F).
- Early Design: Known as the "Kelirengas" (weather tire), it featured large, aggressive tread patterns to bite into snow, unlike the smoother tires of that era.
- Origin: Created in 1934 by Nokian to help trucks navigate harsh Finnish winters, the first winter tire was designed to handle poor roads and snowy conditions.
- Evolution: In 1936, the first passenger car winter tire, the Hakkapeliitta, was introduced.
- Technology: Modern winter tires use softer rubber compounds that remain flexible in the cold, specialized tread designs (sipes) for biting into ice, and deep grooves to displace snow and slush.
- Safety Standards: Look for the Three-Peak Mountain Snowflake (3PMSF) symbol, which indicates a tire is designed for severe winter conditions.
- Usage: It is recommended to install winter tires in sets of four for optimal stability and to use them when temperatures consistently drop below 7°C.
