This is how you benefit


 

Fuel Efficiency Classes


The rolling resistance of your tyres constitutes one of the most important factors of your very own fuel efficiency. The lower the resistance is, the higher your range is. The efficiency classes are graded from G (the lowest efficiency) to A (the highest efficiency), whereas the D class is omitted for vehicles of the categories C1 and C2.

For instance, when an average consumption is 6.6 litre per 100 km, the tyres with the efficiency class A through B will make a difference by increasing the consumption by 0.1 litre, whereas the tyres with the efficiency class B through C will increase the consumption by 0.12 litre, when all the other factors remain the same.*

* All figures specified are only valid when a "normal" vehicle is fully equipped with tyres of the same class and are based on the impact assessment of the European Commission SEC(2008)2860.

Wet braking


This classification involves the braking performance on wet roads. The A class in this case implies shortest braking distance, whereas the F class implies a respectively longer braking distance. For vehicles of the category C1 and C2, the class D is omitted.

The length of your braking distance may be shortened in case of emergency braking with A class tyres by up to 3 meters in contrast to class B tyres - even by 4 meters in contrast to class C tyres.

* All figures specified are only valid when a "normal" vehicle is fully equipped with tyres of the same class during the braking operation at a speed of 80 mph on an averagely smooth road.

External rolling noise


The loudness of the external rolling noise of your tyres is measured in decibels and its value is indicated on the label. The fewer stylised sound waves to the right of the speaker symbol are shown, the lower the external rolling noise of the tyres is in relation to the future European limits.

  • Three black stripes in the label only confirm that the external rolling noise of the tyre type complies with the EU limits valid until 2016.
  • Two black stripes indicate that the noise level is up to 3 dB lower than the noise level of the future limit which will become valid only in 2016.
  • Only one black stripe indicates that the external rolling noise of the tyre is more than 3 dB lower than the EU limits which will become valid in 2016.

* All figures specified are based on the testing procedure specified in the 1222/2009 EC ordinance. The external rolling noise of the tyre does not always correlate with the noise inside the vehicle.

Of course, your own driving behaviour also has a strong impact on your fuel consumption and the road safety, even when you have all the advantages of the correct tyre selection.

  • Driving with the awareness of the ecology can significantly reduce the fuel consumption as well.
  • Regularly checked and correct tyre pressure provides for an optimal wet grip, lower rolling resistance and therefore for low energy losses.
  • The appropriate distance to the vehicles in front of yours leaves you enough space for braking distance and thus reduces the danger of accident.
