The world's first winter tyre with class A wet grip

For the first time, a real winter tyre can also successfully tackle the challenges of wet roads: slush and water. In many sizes, the Nokian WR D4 reach the top of the EU tyre label: class A. For the driver, this means a difference in braking distance of over 18 metres.

The latest product from the pioneer in winter tyre technology, the Nokian WR D4, is a versatile chameleon for the winter roads. It is a grip champion whose unique innovations allow for safe and balanced driving on wet and snowy roads alike. This supreme ruler of every type of winter weather is the world's first premium winter tyre for passenger cars that offers wet grip in the EU tyre label's best A class. Focused innovations from the developer of the winter tyre: The Nokian Block Optimized Siping and the Nokian Twin Trac Silica offer controlled handling and firm grip for extreme conditions.

The extensive size selection of the Nokian WR D4 covers sizes from 14 to 20 inches, with speed ratings from Q (160 km/h) to W (270 km/h). The versatile selection offers exact sizes for sporty rides as well as modern electric vehicles. The special products in the selection employ Flat Run technology, and many products are marked XL for the highest possible load capacity in a passenger car tyre.

The comprehensive range of winter champions especially designed for Central Europe will be totally available to consumers in the autumn of 2015.

Tested precision and peace of mind

Nowadays, winter weather in Central Europe tends to vary between blizzards, driving rain and dry periods. The Nokian WR D4 is created for varying weather, and it represents the finest in Nokian Tyres' tailoring expertise: it is an eco-friendly quality tyre that masters the changing conditions. This uncompromising winter tyre represents the new generation that follows the Nokian WR D3, the winner of multiple comparison tests in motoring magazines.

The precise and safe Nokian WR D4 is a tailor-made product whose structures and rubber compounds were fine-tuned in the laboratories and authentic tests of the world's leading manufacturer of winter tyres. The unique slushplaning test method available on Nokia test track allowed to optimise the slush properties of the tyre. The extensive research was supplemented by relentless testing in the arctic conditions of Nokian Tyres' own Testing Center in Ivalo, Lapland. In addition to the kingdom of ice and snow, the new product's vastly improved wet and dry road characteristics were also fine-tuned on several Central European test tracks.

Safety like never before, also on wet roads

The arrow-like Nokian WR D4 is a genuine winter tyre that steers in a balanced manner and grips absolutely firmly in real winter weather, that is, when driving in snow and slush. Years of work by Nokian Tyres and thousands of kilometres of winter testing all tell the same story: a directional tread pattern is the ideal choice for varying winter conditions.

- A high-quality winter tyre can sense and master all the elements of winter. The excellent grip and handling properties of the Nokian WR D4 are the result of the high-technology functional tread pattern combined with an entirely new Nokian Twin Trac Silica rubber compound and the Nokian Block Optimized Siping. Each tread block and sipe has a specific role. We can now offer drivers the ultimate safety accessory that works reliably and predictably on wet roads, snow and ice alike, says Product Development Manager Olli Seppälä from Nokian Tyres.

The unique nature of the high-performance Nokian WR D4 is also indicated by the EU tyre label, which is designed to make comparing tyres easier for consumers. For the first time, a real winter tyre can also successfully tackle the challenges of wet roads: slush and water. In a few sizes, the Nokian WR D4 can reach the top of the EU tyre label: class A. For the driver, this means a difference in braking distance of over 18 metres, or in other words four car lengths (difference between classes A and F).
