The Greentrac Winter Master S1 is a passenger car winter tire with a directional tread, full-depth 3D sipes and a silica-enriched compound, designed for grip on snow, ice and slush.

• Directional tread pattern reduces noise while enhancing steering precision.
• Full-depth 3D sipes lower the risk of skidding on ice and snow and improve braking and traction.
• V-shaped profile quickly disperses water and slush to preserve grip in winter conditions.
• Silica-enriched compound formulated for low temperatures stays flexible in the cold for strong grip on ice and snow.
• Carries the Three-Peak Mountain Snowflake (3PMSF) symbol.
