Meeting legal requirements is only half the battle in winter conditions. Mobility, even after sudden snow falls or other winter weather, is essential for any transport company. That’s why both the new Dunlop SP346 steer and SP446 drive tyres carry the 3-Peak-Mountain-Snowflake (3PMSF) symbol as well as the M+S marking, meaning these on-road truck tyres are accredited winter products. As a result they meet the highest European requirements for truck winter tyres.
