The three criteria of the EU label.
Since the end of 2012, all car and light commercial vehicle tyres sold must carry an EU label. Countries outside the EU – such as Korea – have also introduced this label or will do so in future. The label and/or sticker rates the tyres according to three criteria: fuel consumption, wet grip class and noise classification.
Reducing rolling resistance saves fuel and therefore also lowers CO2 emissions. The classes range from A (most efficient) to G (least efficient), whereby D is not used for car tyres. For most cars, the difference between the classes represents additional consumption of around 0.1 l/100 km. The fuel saving basically depends on both the vehicle concerned and the driving conditions. An economical driving style can significantly reduce fuel consumption. In order to achieve maximum fuel efficiency and wet grip, the prescribed tyre pressure must also be observed.
Wet grip class.
The wet grip class indicates how well the tyre brakes on wet roads. The classes range from A (shortest braking distance) to F (longest braking distance), whereby classes D and G do not apply to car tyres. Here too, the degree of efficiency basically depends on both the vehicle and the driving conditions. If a vehicle has to undertake an emergency stop, the braking distance of a fully-laden car fitted with A-class tyres can be up to 30% shorter than if fitted with F-class tyres. For a ‘normal’ car travelling at 80 km/h, the braking distance can be up to 18 m shorter.
The noise classification provides information about the tyre’s external noise level. The volume is given as an absolute value in decibels (dB) and displayed using a pictogram with up to three sound waves. In this context, a 10 dB louder noise level is subjectively perceived as being twice as loud. Therefore, 70 dB correspond approximately to the volume of a loud conversation while 80 dB to that of road noise in heavy traffic. The external rolling noise is not necessarily the same as the noise level inside the car.
The EU label. No substitute for the
The new EU tyre label only contains three defined criteria for car and light commercial vehicle tyres, and is not a substitute for the
In addition, the EU label criteria often involve a trade-off: a tyre with extremely low rolling resistance will always have inferior wet grip.
Only with N-marked tyres can you be confident that you're purchasing a high-quality tyre that has been specifically tested for your
