Winter tires for fast and comfortable riding in tough winter conditions. Deep longitudinal grooves together with directional tread pattern and wide shoulder channels ensure exceptional aquaplaning resistance. An additional "winter" wear indicator is applied to the tires, which shows the minimum tread depth recommended for optimal performance in winter conditions. Optimized tire tread profile. Stable grip. High performance properties. Directional tread pattern. Better aquaplaning resistance. Optimized tread block sequencing for a quiet ride. Deep longitudinal grooves improve aquaplaning resistance. High saturation of the tread pattern with sipes. Increased grip on snow and ice. The addition of silica to the rubber compound improves grip on snow, ice and wet roads.
