- Tread compound with functionalised polymers, for excellent Wet and Ice performance
- Dunlop Touch Technology
- Better cornering in both wet and dry conditions
- Excellent grip on snow
- Very good wear resistance
- Run on flat
- Excellent grip and control at high speeds on all surfaces
Enhanced snow and ice traction. The unique tread design puts a high number of biting edges in contact with the road, giving you enhanced traction on snow and ice. Deep snow notches grab onto the surface, adding extra grip when accelerating, braking and hill climbing.
Exceptional performance on winter roads. The SP Winter Sport 4D provides exceptional winter handling and braking ability for high performance cars. Combining a unique tread design with high grip materials, it is designed to deliver optimal control on snow, ice, wet and dry surfaces.
Control and grip in wet conditions. For days when roads are wet or thawing, the SP Winter Sport 4D features directional grooves designed to evacuate water quickly and prevent aquaplaning. The high grip compound is optimised to deliver shorter braking distances on wet roads.
Fuel efficient design. With its lightweight construction and materials, the SP Winter Sport 4D requires less energy to roll – which means lower fuel costs and CO2 emissions from your journeys.
Superb winter handling and grip for high performance cars: Exceptional performance on winter roads, enhanced snow and ice traction, control and grip in wet conditions and fuel efficient design.
RunOnFlat. Dunlop Self Supporting Technology (DSST)Dunlop RunOnFlat Technology allows for continued driving after a puncture or blowout for up to 80km. RunOnFlat tyres use reinforced sidewalls, which enable the tyre to maintain mobility after a complete loss of air pressure.Safety Notice Dunlop RunOnFlat tyres should only be mounted on cars that are designed for run flat tyres and equipped with a fully operating tyre pressure warning device, such as Dunlop WARNAIR. A maximum distance of 80km/50 miles and maximum speed of 80 kmh/50 mph should not be exceeded. Please refer to your car’s manual as manufacturers’ advice for a particular vehicle may differ.
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.
