Nokian Tyres Hakkapeliitta 9. FEATURES AND BENEFITS: Winter weather traction; Enhanced controllability; Fuel efficient performance; High driving comfort levels; Run flat tire model; . OVERVIEW: The Nokian Tyres Hakkapeliitta 9 is a touring winter tire manufactured for passenger vehicles and SUVs. This model is made for electric vehicles.The tire promotes a secure winter weather performance. It is able to perform in severe winter conditions thanks to the combination of the detailed directional tread and the durable winter compound. The middle tread blocks' snow-gripping cuts and the high-density zigzag siping pattern enhance the number of biting edges gripping the ice- and snow-covered road surface with extra biting edges. The durable compound keeps the rubber flexibility in colder temperatures, guaranteeing the tire's secure performing capability in various winter situations. Versatile studs can be added to the tread area as it is pinned, which would further enhance the grip on the road surface when driving on ice and snow. The zigzag circumferential and angled lateral grooves prevent hydroplaning by dispersing water and slush from below the footprint, maintaining the surface contact and boosting the winter weather driving safety.The tread design and the stronger structure work together to enhance the controllability. The tread's directional pattern closely follows the road surface to enhance the steering responsiveness. The tread's constant road contact and ideal footprint boost the grip on the road surface and enhance the steering response time and accuracy to the driver's commands. The high-tensile steel belt structure enhances the driving stability. It secures the tire's structure against the driving pressure affecting the model while the tires are in motion, which maximizes the drive's control over the vehicle at all times. This combination ensures a secure performing capability in all winter weather.The model was molded from a special eco-friendly tire compound. This compound enhances the surface traction and eases the pressure off the tire during its performance. As a result, it significantly lowers the model's rolling resistance. The rolling resistance is the driving pressure affecting the tire which determines the vehicle's fuel consumption needed to keep the tires in motion. By lessening the rolling resistance, the tire decreases the vehicle's fuel intake and CO2 emissions, guaranteeing a fuel efficient and environmentally friendly driving experience.The Hakkapeliitta 9 promotes a comfortable drive. The reinforced internal structure and the ideal tread design minimize the road noise and vibration levels. While the tires are in motion, the stronger internal structure ensures the model's close road contact. In this manner, the tire manages to absorb the shock of driving, reducing the vibrations felt in the vehicle's cabin. This structure and the tread design stabilize the tread elements, preventing tread flexing. This ensures lower road and tread pattern noise formations during the drive, providing an enjoyable drive throughout the tire's performance.Nokian's studdable winter tires require special studs. For this reason, Nokian winter tires can only be studded at their factory. Therefore, tire shops will not be able to install studs into Nokian tires in the US.Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
