Our tests have shown that aggressive Directional and balanced picture most effective protector for studded tires, as for moving snow, and on shuge. Behavior on dry roads improved by strengthening the central part of the tread: the central pieces combined with a central rib. This surface structure can significantly improve the stability and accuracy of management behavior. Due to the geometry of the tread nor snow, nor sleet does not accumulate in the tire, it is purified naturally. Beveled shoulder area of the tread in the tire Nokian Hakkapeliitta 7 slashpleningu improved resistance properties (sliding through the slush and snow porridge). This has been achieved, bevel on both sides of the shoulder band tires. Because of this, the tire effectively cut sheet slush, snow porridge better is displaced from the contact patch the tire. As a result, sloping shoulder tread zone Nokian Hakkapeliitta 7 turned out to a few millimeters narrower than the Hakkapeliitta 5.
Therefore, in the same sizes pressure on the road surface with tires Nokian Hakkapeliitta 7 is slightly higher than the previous model. 3D sipes in the tread sipes of three-dimensional sipes used (3D), which in its own way adds to his toughness and impact the behavior of the tires on dry road. The new rubber compound based on kriosilana Previously it was difficult to connect a large number of natural rubber with a lot of silica (silicon dioxide), which is used binder instead of black. Division of Materials Nokian Tyres had a lot of trials and tests, as a result of a new composition: natural rubber, silica and canola oil.
