Reliable without surprises - The excellent braking and accelerating grip of the Nokian Hakkapeliitta RSi is the fruit of new technical insights. The brake booster system consists of a dense network of tooth-like sipes that significantly increase the tire's grip surface. Shoulder sipes play the most crucial role in braking, and their grip surface has been increased by over 40% in comparison with the previous friction tire. During acceleration the tire's sturdy central area ensures continuous grip. The proportion of lateral and longitudinal grip has been balanced so that the tire performs without surprises in sudden situations, and even compensates for the driver's minor steering mistakes. The tire offers a safe latitude in borderline situations. The Nokian Hakkapeliitta RSi has been designed to utilize the advanced properties of ABS brakes, traction control and stability programs available in new cars.
Stable - Thanks to its tyre structure and wedge-shaped sipes, the Nokian Hakkapeliitta RSi offers stable driving. Built on the principle of deep-shallow-deep, the sipe network gives the tyre extreme stability and grip. Driving stability is reinforced by the central area tread pattern being constructed of double blocks and a uniform centre rib. The tyre has a strong arrow-like pattern, which have a predefined direction of rotation.
Accurate - The Nokian Hakkapeliitta RSi has an accurate and neutral driving response and does not oversteer unexpectedly. The straight and broad tread, and the rigid, uniform center rib reinforce steering feel in bare conditions and improve accuracy. For the driver, safety and stability appear as quietness and a feel of control resulting from the accurate driving response.
Economical and environmentally responsible - The Nokian Hakkapeliitta RSi is also economical and environmentally friendly. The new tire rolls lightly and saves on fuel costs. The rolling resistance of the tyre is better than the rolling resistance of most summer tires. It also wears evenly and maintains its impeccable grip when worn. The tread has an entirely new canola oil-silica rubber compound, which gives the tire excellent winter properties, low rolling resistance and, in the friction tires group, a good wet grip. The tire has been manufactured without harmful high-aromatic oils.
Silent - Silence is one of the pleasant properties of friction tires. The pass-by noise of the Nokian Hakkapeliitta RSi remains clearly below new EU norms.
Neat and nifty - Thanks to the new manufacturing technique, the Nokian Hakkapeliitta RSi is stylish and particularly neat in appearance. The tread has four Driving Safety Indicators (DSI), which indicate the depth of the main groove in millimeters. In most sizes (> 14 inch tires), the mudstopper, familiar from Nokian summer tires, protects the rim against impurities by preventing dirt and gravel from entering between the rim and the tire. The low profile, broad tires are usually mounted on handsome alloy wheels. All Nokian Hakkapeliitta RSi tires with an aspect ratio of 55 or less have a rimguard, which prevents damage to the rim when parking too close to the pavement edge, for example.
