- Optimized tread design - The updated tread design in combination with the rounder profile, helps to increase the traction of each pattern section on the snow. Increased traction on snowy surfaces - Improved tread pattern compound - New generation of winter compound improves the balance between Hysteresis (wet behavior) and Compound Softness (snow behavior) - achieved through High Vinyl Poly Butadiene. Excellent Balance between Wet and Snow performance - Interactive Brickwork siping (I.B.S.) - Specific sipe geometry allows ?vertical? and independent movements of tread ?bricks?. Increased contact area to enhance braking also on irregular surfaces Stability in lateral / longitudinal directions to improve handling - Innovative Base Compound and Bead Geometry - Excellent Dry Stability and Handling. Outstanding safe driving on dry road conditions
