In the claws of winter If after the summer, used winter tyres are fitted to your car, they should be checked thoroughly. It is important to check both the tread depth and the condition of the studs on studded tyres. Tread depth is measured at the main grooves, which means the wider grooves at the centre of the tread which cover about 3/4 of the tread's width. Studded tyres and friction tyres have quite different characteristics, so when buying new tyres it is worth pausing to consider one's own style of driving and the conditions in which the vehicle will most commonly be used. Winter tyres differ from tyres marked MS (Mud & snow). Innovations improve the safety of tyres Ice, snow, and changing conditions mean that winter tyres must be reliable and durable. Nokian's studded and friction winter tyres feature many innovations that make them the right choice for Nordic winter driving. For example, the square stud and the ”bear claw” both enhance the grip of studded tyres, and the pump sipe ensures that friction tyres remain in contact with the road. Studded and studless winter tyres for cars are some of Nokian Tyre's key products. Winter tyres account for over 80% of this unit's turnover. Nokian's winter tyres represent the master work of the experts in Nordic conditions, and product development is guided by the principle of sustainable safety. A tyre's journey to the customer takes many twists and turns The tyre manufacturing process is complicated, and involves the transformation of raw materials into the finished product. All tyres are checked both visually and mechanically, and then tested in real winter conditions at Nokian Tyre's own test track at Ivalo, Finland. The winter tyre sector is seasonal in nature, and with its efficient distribution network Nokian Tyres aims to guarantee customers access to the very tyres they need, just when they need them. Nokian's Hakkapeliitta winter tyre family represents the peak of tyre design, and is the result of years of development, expertise and professionalism, from the production line to the winter road.

Summer tyres for the quality conscious motorist Nokian summer tyres are made to fulfil the demands of three seasons; spring, summer and autumn. Summer tyres need to function on hot asphalt, in the pouring rain and on bumpy unmetalled country roads. When shoosing summer tyres it is worth paying attention to the tyre's speed rating, aquaplaning characteristics and one's own driving style. Nokian summer tyres are the choice of the demanding motorist. The development of a completely new car tyre takes from two to four years, and the car tyre unit invests about 4% of turnover on product development. Car tyres are tested at Nokian Tyre's own test tracks, at Nokia and Ivalo. Nokian Tyre's position in the Nordic tyre sector did not come about by chance, but rather by hard work, innovation and professionalism. Like one family Nokian Tyres has developed the completely new Hakka tyre family for the snowless times of the year when conditions may nevertheless be changeable. Hakka summer tyres are available in various speed ratings, and so products can be found to suit customers' particular requirements in particular situations. Hakka summer tyres and other quality summer tyres are available for cars, vans and SUVs. All Nokian Hakka summer tyres come with the quality assurance of Hakka Protection, which offers an extensive guarantee on the product. If a correctly fitted and appropriately used tyre accidently breaks and becomes unusable, the customer will receive a replacement free of charge from an outlet selling Nokian Tyres in Finland, Sweden or Norway. Summer tyres and rolling resistance By choosing the right tyres it is possible to have an effect on the environment. As tyres roll across the surface of the road friction is created, which is known as rolling resistance. A high rolling resistance will increase fuel consumption. So, by choosing the right tyres it is possible to reduce exhaust emissions, and to play a part in preserving the environment for our future driving pleasure.
