The layer of water above the ice is the biggest contributor to loss of traction. It causes 'micro hydroplaning' on icy surfaces. A traditional rubber rides on the surface water because the thickness of the layer of water in the -6 to 0°C zone becomes more than the normal undulations of the tyre surface can manage to work effectively. YOKOHAMA´s original SUPER WATER-ABSORPTIVE COMPOUND technology can put the tyre in contact with the actual ice by removing water with powerful absorbent compounds.
Removes Water film from the ice surface by its cavity shape. Delivers micro edge effects on the ice surface by its hard shell. Keeps tread-block solid by its hard shell construction.
Absorptive White Gel
Removes water film from the ice surface by a suitable undulation for the tyre surface delivered by its flexible property.
Tread Pattern and Construction Technologies
Anti Energy-Loss Profile
Delivers a fuel saving performance and stability by controlling a deflection of the tyre.
Asymmetric Tread pattern design
Inner zone, an effective tread pattern area for ice performance, has more actual contact area and more sipes than outer zone in order to maximize the friction and edge effects on ice surface.
Triple 3-D dimple sipes / Triple 3-D sipes
2 types of original 3-dimension shaped sipes are varied to get suitable effects and balances on each tread area. The surfaces of 3-D sipes avoid uneven deflection of blocks by supporting each other. It delivers excellent ice and snow performance with its maximized actual contact area and edge effects.
The belted blocks with a large, wide, centralized block design improve the braking stability as well as the performance on wet, dry and icy road surfaces.
Micro Diagonal Sipes
Deliver optimum performance even without a break-in period. Outer zone, an effective tread area for snow performance, has more grooves in order to maximize the traction and edge effects on snow surface.
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.
