Nokian Powerproof

Dual Zone Safety provides grip as well as precision and manoeuvrability. The Power Zone maximises manoeuvrability on dry surfaces while the Wet Safety Zone is tasked with minimising the chances of aquaplaning and increases safety and tranquillity conditions in wet situations.
Power Zone. Precision & manoeuvrability. Driving on dry roads is rigorous and undisturbed by the combination of various advancements such as the innovative and solid profile, the rigid tread blocks and its clarified pattern, not to mention the grooves with inclined edges.
The Wet Safety Zone ensures a controlled grip on wet surfaces. The trapezoidal drainage grooves divide the middle groove and the one located towards the inner shoulder. The resistance to skidding on water film is made more infallible thanks to the expanded wavy pattern at the base of the grooves. This enables them to store water while hastening its drainage. The inclined grooves also increase the dynamic response to aquaplaning. The distribution of the groove edges is more uniform and they have sides with horned notches that expedite water flow.

Half-ball shaped notches adorn the walls of the longitudinal grooves, defining a much more pleasant drive. This innovative idea delivers silent grooves, reducing the generation of sounds inside the car as well as rolling noise. Less air resistance, less surface heat of the tyre, and slower wear are the other benefits of this new design.
