Structure de surface multi-couche A good feel for the driving surface is an essential characteristic of a reliable and safe winter tyre. The precise steering feel of the Nokian Hakkapeliitta R allows the driver to detect changes in the level of friction. The grip limit is wide, providing drivers with even better opportunities to react in a timely manner to changes in grip. The multi-layered tread structure that has been specially developed for non-studded tyres and the tread compound combine to provide the Nokian Hakkapeliitta R with excellent evasion and steering capabilities, as well as good stability on bare roads. The tyre remains stable regardless of the variation in winter weather. The block geometry of the tread also improves steering on grooved roads. The multi-layered structure also reduces the heat generation and rolling resistance of the tyre, allowing the non-studded tyre to roll especially lightly and conserve energy. For a driver, this means good fuel economy, which also results in eco-friendliness. At the same time, the CO2 emissions from traffic are reduced.
