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.
Specific bead seat system. Strengthens the link between tyre and rim for a more precise driving experience. Like the grip between your hand and the steering wheel, the Specific Bead Seat System enhances control and conveys outstanding road feedback.Benefits Enhanced road feedback; greater stability and precision.
Silica-Plus Compound. A motorsport derived tread compound that delivers high levels of grip, particularly on wet roads and in low temperatures.Benefits Superb braking and acceleration performance; high grip in wet and cold-weather conditions; low wear and tear.
Jointless Belt (JLB). A Hybrid Overlay Technology that reduces circumferential deformations at high speeds.Benefits Superior high speed stability
Maximum Flange Shield (MFS). A rim flange protection system. MFS employs a profile of rubber that runs around the circumference of the tyre above the wheel flange. This creates a protective buffer zone.* Benefits Protects expensive alloy wheels from kerbing.* Only available in select sizes
4D Sipe System. The 4D Sipe system sees the tread separated into a number of blocks that increase friction and stability during cornering. The system delivers superb lateral grip in snow.Benefits Superb cornering, even in snow.
Variable land to sea ratio. Asymmetric tread design with a variable land to sea ratio delivers high levels of aquaplaning resistance. The massive outer shoulder block ensures rapid and turbulence free water drainage, while also ensuring outstanding cornering stability.Benefits High aquaplaning resistance; increased road contact; enhanced cornering stability and steering precision.
Flatter tread profile. The new generation of Dunlop tyres features a flatter tread profile with a 4-8% bigger contact patch, depending on size and type of tyre. A bigger contact patch delivers more stability and enhanced road feedback, allowing tires to respond quickly and precisely.Benefits Increased stability and steering precision; reduced heel and toe wear; excellent cornering stability and precision; superior dry grip.
Multi Blade System. Winter driving conditions can vary greatly. From cold and dry to snow or sleet, these conditions make very high demands on a tyre. Dunlop’s multiple blade system meets this challenge head on, with different types of blades for varying winter road conditions. Benefits Consistent performance in various winter conditions.
Functional Polymers. Functional Polymers in the tread compound produce enhanced performance characteristics at low temperatures, improving road adhesion when winter temperatures plummet.Benefits Exceptional grip at low temperatures.
Multi Radius Tread (MRT). MRT designs employ ten different radii and are therefore more precise. This results in highly effective pressure deployment on the road contact patch. The effect is smoother transitions from straight to corner, leading to more precise and progressive reactions.Benefits Significantly better control over the evolution of the footprint in all driving conditions; responsive wet and dry handling; increased cornering control.
Foam-in-Tyre Technology (FIT)
Car interior noise has 3 main causes:
Wind noise (created by air-flow at high speed)
Tread/block road rumble. “Airpumping” also known as “groove resonance” , where the grooves are compressed and then released again. (Structural) Vibrations of the tyre/carcass.
Tyre noise is mainly transmitted by:
- Airborne noise: Noise waves transmitted through air
- Body noise: Transmission by vehicle suspension
One of the biggest noise sources, is the so-called Cavity Resonance which is transmitted into the car as body noise because of the axle construction.
Foamin Tyre (FIT)
'How does Foamin Tyre work'
Once the tyre has been heated, a foam strip is fitted to the inner liner. This reduces tyre (carcass) noise considerably.
Principle of operation:
- Elimination of resonance peaks.
- Reduction of interior car noise by a number of dB, to half of the tyre noise.
- Relatively cost efficient
- Stable through the full life of the tyre
- Light enough not to influence running performance, roll resistance or high speed efficiency
- Currently available in Summer and Winter, also as All Season and ROF later.
- Can be repaired
Effect of the tyre on noise perception
Sounds are transmitted by 2 main mechanisms: By air movement (Air resonance): The air molecules are stimulated to vibrate (wave form).
By structural resonance (Body resonance): Vibrations are transmitted by the vehicle structure.
A large part of inerior car noise is due to resonance caused by vibration of the tyres. This is transmitted to the inside of the car via the structure (body resonance). Counter measures taken at noise source, in this case, at the tyre, are easier and more effective than they would be at other car components, e.g. at the drive train or the body.
How can the vibrations in the tyres be reduced?
Fitting a foam strip to the inner liner of the tyre helps to markedly reduce the tyre (carcass) noise. Reduced resonance in peak range by up to 11dB(A) This makes a reduction of interior car noise of up to 3 - 4dB(A), possible. This means that it is only half as loud in the car as it would have been with normal tyres.
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.
