The Nokian Powerproof is a summer tire for passenger cars. It perfectly handles high-speed lane changes as well as sudden braking. The unique Dual Zone Safety concept ensures grip and precise handling.
The original design called Dual Zone Safety ensures that the tire benefits from excellent grip and precision in handling. The Power Zone allows for perfect handling on dry roads while the Wet Safety Zone greatly limits the risks associated with aquaplaning and thus increases the feeling of safety on wet ground. The new durable profile, the sleek design and the resistant blocks of the tread, the sloping pattern of the grooves with steep edges are all ingredients allowing for driving in dry conditions as precise as it is controlled.
Wet Safety Zone: a biting grip on wet roads. The winding grooves are wider at the bottom than at the surface, which gives the tire the ability to store water, then to precipitate its flow to greatly reduce the risks of skidding on the water film. The grooves are evenly distributed in the pattern and have indented faces like horns to expel water more quickly.
The half-sphere notches, like those on a golf ball, present on the sides of the circumferential grooves, significantly increase the pleasure of driving. With this innovation, sound emissions, whether inside or outside the cabin, are truly minimized. This pattern also reduces air resistance and lowers the rubber temperature, which generates greater resistance to deterioration.
