Rock 868S: High-Performance Winter Tyres
The Rock 868S tyre model is designed to provide optimal resistance on snow and ice, thanks to its asymmetrical design specifically crafted for winter conditions. The outer part of the tyre features a high saturation pattern that ensures excellent handling, while the wide internal grooves ensure efficient water evacuation, thus reducing the risk of skidding.
- Zigzag Longitudinal Grooves: This unique design creates a gear-like effect between the tyre and the snowy surface, thereby improving driving stability. The strategic arrangement of 3 to 4 wide longitudinal grooves allows for effective evacuation of water, mud, and snow, significantly enhancing the tyre's anti-slip performance.
- 3D Steel Sipes Design: Inside, a dense distribution of steel sipes maximises traction and braking on snowy and icy roads. Outside, a lower density of sipes ensures exceptional handling.
- New Silica Formulation: Thanks to a new formula incorporating silica, the tyre retains its viscoelastic properties even at extreme temperatures from -30°C to -40°C. This allows for better road grip, increasing the contact area and the coefficient of friction between the tread and the ice, thus ensuring safer driving in winter conditions.
