External rolling noise
The new EU tyre label focuses on the development of external rolling noise. Interior noise has not been taken into account. If millions of cars had quieter tyres, noise pollution would be significantly reduced. External rolling noise caused by tyres is measured in decibels. External rolling noise does not correspond to noise heard inside the vehicle.
- In addition to the noise value reported in decibels (dB(A)), the label shows if the tyre's noise level exceeds the maximum value in the future type approval (3 black waves = noisy tyre), meets the future type approval requirements or is up to 3 dB quieter (2 black waves = average tyre), or is over 3 dB quieter than what is required by the new type approval (1 black wave = quiet tyre). The tyre approvals will change in November 2012.
Three classes reported in decibels. The more black bars are on the sticker, the higher the external rolling noise is. The measured value is also reported with a dB figure.
Fuel savings and road safety are highly dependent on the driver’s behaviour. Take into account the following issues:
- Economic driving can significantly reduce fuel consumption
- To optimise road safety and driving comfort, tyre pressure needs to be checked at regular intervals
- If the tyre pressure is too low, the tyre wears out much quicker than usual; it also affects fuel consumption and poses a clear risk in terms of road safety
- A responsible motorist is always aware of the properties and condition of his/her tyres. Only a driver who knows the vehicle and tyres can adjust the speed and safety distance to match the current weather.
