What does the label mean?
FUEL EFFICIENCY (Rolling Resistance)7 classes from G (least efficient) to A (most efficient)
Effect may vary among vehicles and driving conditions, but the difference between a G and an A class for a complete set of tyres could reduce fuel consumption by up to 7.5 %* and even more in case of trucks.
WET GRIP (Braking Performance)7 classes from G (longest braking distances) to A (shortest braking distances)
Effect may vary among vehicles and driving conditions, but in the case of full braking, the difference between a G and an A class for a set of four identical tyres could be up to 30% shorter braking distance (e.g. for a typical passenger car driving at 80 km/h speed this could be up to 18m shorter braking distance)*.
NOISE (Exterior Rolling Noise – not cabin noise)
In addition to the noise value in Decibel dB(A) a pictogram displays whether the tyre external rolling noise performance is above the future European mandatory limit value
(3 black bars= noisier tyre), between the future limit value and 3dB below
(2 black bars= average tyre) or more than 3 dB below the future limit value
(1 black bar = low noise tyre).
NB: The tyre external rolling noise is not entirely correlated to vehicle interior noise.
What else is important when choosing new tyres?
The label does not address every factor which is critical to overall tyre performance:
- Dry handling
- Dry grip (straight line)
- Dry grip (circles/cornering)
- Wet handling
- Wet grip (circles/cornering)
- Resistance to aquaplaning (straight/curved)
- High-speed stability
- Interior noise
- Tread wear
Please remember the following:
Actual fuel savings and road safety depend heavily on the behaviour of drivers:
- eco-driving can significantly reduce fuel consumption
- tyre pressures should be regularly checked to optimise wet grip and fuel efficiency performance
- stopping distances should always be strictly respected
