On the 1st November, 2012, all tyres sold in the EU are labelled in compliance with a standardised system. This label informs customers of three properties of the tyre:
- Wet grip: this figure describes the grip properties on a wet road surface. The better the wet grip, the shorter the braking distance. This is defined by a class ranging from F (longest braking distance) to A (shortest braking distance), when braking at 49 mph. The effectiveness depends on the vehicle and the driving conditions.
- Fuel efficiency: A tyre becomes deformed when rotating, which affects its ability to roll, resulting in a loss of energy. The higher the deformation, the higher the tyre's rolling resistance, and consequently the more fuel that is required to move the vehicle forward. This is defined by classification ranging from A (most efficient) to G (least efficient).
- External tyre noise: The tyre label specifies the level of external rolling noise in decibels (dB) and as one, two or three sound waves.
One black bar indicates that the external rolling noise is at least 3 dB lower than the EU threshold applicable from 2016.
Two black bars indicate that the external rolling noise is equal to or at most 3 dB lower than the EU threshold applicable from 2016.
Three black bars indicate that the external rolling noise does not comply with the threshold applicable from 2016.
Note - External rolling noise does not necessarily represent the noise you will hear inside the vehicle.
Actual fuel savings and road safety depend heavily on the behaviour of the driver, and the following points should be taken into account:
Economical driving can significantly reduce fuel consumption
Tyre pressures should be regularly checked to optimise wet grip and fuel efficiency
Speed limits should always be strictly respected
