External rolling noise


The new EU tyre label focuses on the reduction of external rolling noise. Interior noise has not been taken into account. If millions of vehicles 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 the 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 type approvals will change in November 2012. 

External rolling noise

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 driving safety are strongly connected to driver behaviour. Please take into account the following: 

  • Economical driving can significantly reduce fuel consumption
  • Choose your tyre type according to the intended application. Check the suitability of the tyres from Nokian Tyres’ recommendations.
  • Tyre pressure should be checked regularly in order to optimise driving safety and comfort.
  • Air pressure that is too low wears the tyre significantly more, affects fuel consumption, and is a clear risk for road safety
  • A responsible driver is always aware of the characteristics 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.
