Nokian HAKKAPELIITTA R2 SUV Performance-Winter Radial Tire-235/75R15 105R This new non-studded introduction to the Hakkapeliitta family of winter tires represents the core competence of Nokian Tyres: the worlds leading winter tire expertise. First-class winter grip, more precise handling - Diamond-tough grip particles that have the appearance of a multi-edged crystal have been added to the rubber compound in order to improve grip on ice by grabbing onto the driving surface. The new cryo-silane based winter silica compound works safely across a wide temperature range. The compound creates exceptional grip on ice, snow, and wet roads, and excellent wear resistance. Pump Sipes - The pocket-type sipes on the tire shoulder remove, or even pump, water out of the road surface, ensuring stable and sure grip.
