Nokian WR A4
The Nokian WR A4 is a premium-range winter tyre featuring an asymmetric tread pattern. This is the ideal choice for high-power vehicles. The state-of-the-art technology used in this model guarantees an exceptionally safe and comfortable drive.
The tread of the Nokian WR A4 features cutting-edge Functional Performance Siping blades and a Performance Traction Silica rubber compound, but these are only the basic components of the model's sophisticated design. It is the details that really make the difference. The Nokian WR A4 allows for hassle-free driving in rapidly changing winter conditions.
The benefits offered by the Nokian WR A4 include stability when driving through snowstorms, slush or pouring rain or on sun-scorched asphalt, which encourages higher speeds. The central part of the tyre features a Centipede Siping blade, the design of which is inspired by nature and which improves grip even further in winter conditions. How does it work? The jagged blades resemble a centipede. They effectively bite into the surface, improving control over the vehicle.
A stiffened shoulder (side area) provides tyre stability, preventing the tyre from "gliding". This is particularly important when driving at high speeds or performing dynamic manoeuvres. A variety of tread block sizes are linked to each other with support lifts to make sure that they do not move during acceleration.
The self-locking 3D blades on the tyre surface improve transverse rigidity, while the specially designed arrangement of grooves ("Coanda Technology") improves water dispersal. Nokian's copyrighted solution makes it possible to maintain stability during sudden changes in weather conditions.
The Nokian WR A4 provides not only safety, but also comfort and cost-effectiveness. The special rubber compound increases the durability of the model, reduces tyre noise (by reducing the vibrations transferred to the rim and to the interior of the vehicle) and lowers rolling resistance.
The performance of the Nokian WR A4 is the result of tests carried out at the "White Hell" testing centre in Ivalo (Lapland), which examined the tyre's behaviour in the most extreme winter conditions. Its grip on dry and wet surfaces was also tested on tracks in Germany and Spain. The Nokian WR A4 is a tyre you can rely on.
Nokian is Europe's northernmost tyre manufacturer. The Finnish company brought the first winter tyre to market and has been improving its product range successfully ever since. The brand's tyres are noted for their superb quality and regularly come out top in tests.
