EU tyre label

Only 3 good reasons
to take a closer look.

The 3 criteria of the EU label.

Since the end of 2012, commercially available car and truck tyres have had to feature an EU label. Even countries outside the EU - such as Korea - have already introduced this label or intend to do so. The label/sticker provides an assessment based on 3 criteria: fuel consumption, wet grip class and noise classification.

Fuel consumption

The reduction of roll resistance saves fuel thereby minimising CO2 emissions. Classes ranges from A (very low consumption) to G (very high consumption) and D does not apply to car tyres. In most cases, the difference between the classes corresponds to an increase in consumption of around 0.1l/100 km. Fuel savings generally depend on the respective vehicle and driving conditions. An economic style of driving can significantly reduce fuel consumption. The prescribed tyre pressure must also be observed to ensure optimum fuel efficiency and wet grip.

Wet grip class.

The wet grip class indicates how well the tyres brake on wet surfaces. Classes range from A (shortest breaking distance) to F (longest braking distance), and classes D and G do not exist for car tyres. Again, the degree of efficiency also fundamentally depends on the vehicle and the driving conditions. In the event of emergency braking, the braking distances for a fully-loaded vehicle can be shortened by up 30% if using class A instead of class F tyres. For ‘normal’ cars travelling at 80 km/h, the braking distance can be shortened up to 18 m.

Noise classification.

The noise classification informs you how loud the tyres are when the vehicle drives past. The volume is indicated as an absolute measurement in decibels (dB) and is presented using up to 3 stylised sound waves. Be aware that a noise level that is 10 dB will be subjectively perceived as being twice as loud. 70 dB corresponds to a loud conversation and 80 dB is like road noise in heavy traffic. Incidentally, the external rolling noise is not the same as the noise level in the interior.

The EU label - no substitute for Porsche N-marking.

The new EU tyre label only comprises 3 fixed criteria for car and truck tyres and is no substitute for Porsche’s N-marking.

In addition, there is often a conflict of goals with respect to the criteria of the EU label - a specific tyre may exhibit especially low roll resistance but also features poor wet grip. Porsche makes no compromises when it comes to safety and rates grip - both on wet and dry surfaces - as higher than fuel efficiency during tyre tests. The savings potential of a tyre optimised in terms of roll resistance may sound tempting but, in an emergency situation, every metre of braking distance counts. Only N-marked tyres give you the peace of mind that you have purchased top quality tyres which have been tested on your model of Porsche.
