New Nokian WR A4 – Forget the Forecasts
- Advanced winter grip on dry, wet and snow-covered roads due to Functional Performance Siping
- Extremely stable and balanced high-speed performance
- Maximum comfort
Functional Performance Siping. More winter grip, better steering feel. Each tread block and sipe in the stylish tread pattern has a precise shape and role, and this can be felt in the excellent grip and handling properties. The stiff outer shoulder, the Centipede Siping in the centre area and the zone-optimised siping all form a controlled combination that allows the Nokian WR A4 to roll safely and comfortably in varying Central European winter weather.
Centipede Siping. Maximum snow grip, precise handling. The centre area is dominated by a sturdy longitudinal rib consisting of tread blocks with jagged sipes that resemble the footprints of a centipede. The staggered 3-dimensional Centipede Siping offers maximum contact surface and works with full effect at different turning angles, increasing grip on snow and slush and improving control.
Performance Traction Silica rubber compound. Precise grip, excellent wear resistance, low fuel consumption. The rubber compound, which contains natural rubber, silica and canola oil, ensures excellent winter grip. This state-of-the-art compound innovation also improves driving stability and wear resistance. Canola oil provides tear strength. Tear strength makes the tyre extremely resistant to wear, impacts and punctures. The large amounts of natural rubber and rapeseed oil ensure that the excellent winter grip properties remain the same even as temperatures change and the kilometres add up. Extremely low rolling resistance results in low fuel consumption.
Groove Lifts. Excellent handling. The tread blocks on the tyre shoulders are supported by steep groove lifts that increase stiffness and improve handling.
Snow Claws. Strong snow grip. Snow Claws were shaped on the longitudinal grooves of the tread blocks to provide much-needed grip on winter roads. Snow Claws grip the surface relentlessly on soft snow and in soft terrain.
Nokian Tyres Coanda Technology. Effective aquaplaning prevention. The curved, ramp-like design of the tread blocks on the inner and outer shoulder guides and accelerates the flow of water from the longitudinal grooves into the transverse grooves. The excellent aquaplaning prevention properties are retained, even as the tyre wears down.
Silent Sidewall Technology. More driving comfort. The tailored special rubber compound between the sidewall and tread actively filters the sound and vibration originating from the driving surface, preventing the passage of harmful sound waves that irritate the human ear through the sidewall into the passenger compartment.
Special Clinch rubber compound. Optimised durability, lower rolling noise. The rubber compound presses flexibly against the wheel flange, providing the bead area with more durability. The innovation also effectively minimises the interior noise, since it dampens the vibrations from the tyre body, preventing them from passing into the tyre and further inside the vehicle.
Polished Grooves. Safety and elegance. The polished longitudinal and lateral grooves facilitatethe removal of snow and slush.
Since 1st November, 2012 all tyres made after 1st July, 2012 must show the European Tyre Label.
The European Union has developed this new provision to promote economic and ecological efficiency and ensure road safety.
Disadvantages The Tyre Label can provide an overview and give the customer more transparency, but it only covers three criteria. For an extensive evaluation of a tyre, however, far more performance characteristics are relevant. Especially in the search for suitable winter tyres the test results from different test institutions such as the ADAC are much more stringent.
We'd like to point out that it is the manufacturer that labels the tyre and provides us with this information. If you do not find the label values, either the manufacturer did not inform us of the label, or the product was manufactured before July, 2012. Before that date, tyres had not yet been required to carry a label, so in some cases it is possible to purchase a tyre without a Tyre Label.
The tyres are classified in terms of three performance characteristics:
• Fuel Efficiency (letters A to G)
• Wet Grip (letters A to G)
• External Noise
Finally, it is the driver that determines the fuel consumption. In order to reduce this over the long-term, by being careful during acceleration drivers can become more fuel-efficient and environmentally conscious.
Regularly checking tyre pressure helps to improve rolling resistance, reduces energy loss, and supports optimum adhesion in wet conditions. To reduce the risk of accidents and ensure your and the safety of other road users, always keep a reasonable distance.

The classification in terms of fuel efficiency is divided into seven classes, from the A-class (the highest) to G-class (the
lowest). A tyre in the A-class consumes 0.1 litres less at 100km than a tyre in the B-class. An essential component for fuel
efficiency is the rolling resistance or rolling friction.
Rolling resistance is the force that opposes motion. It is formed, for example, when a wheel is rolling. Rolling resistance depends not only on the geometry but also on the properties of the material.
Average Average value is between C-E. Class D is not used.
It shows how efficient the vehicle can brake on wet roads. Wet grip is an important feature especially with summer tyres.
Class A has the highest safety and the shortest braking distances. Class F has low security and the longest braking distance.
The wet grip classes are based on test driving on wet roads with a speed of approximately 80 km/h. The difference between the braking distance of the tyres is 3-5 feet per grade. E.g., the difference in braking distance between Class A and Class F are up to 18 metres.
Average The average value of the tyres is between class B-E. Class D and G is not used.
The symbol indicates the external rolling noise in decibels and as a 3 class sound wave symbol to clarify whether the tire can
keep the recommended level. External rolling noise does not correspond to tyre noise inside the compartment.
A continuous sound level above 80 decibel can cause health problems.
Three sound waves symbolize the worst results. These are the tyres that exceed the maximum limit of approval. A symbol of 2 sound waves have noise level that corresponds with the approved sound level. Tyres that are marked with 1 sound wave are over three decibel quieter than the approval.
