EU tyre label: Noise

Choosing truck tyres with a good noise rating will lower the impact of your driving on the surrounding environment.

What the EU noise rating measures

The EU rating measures the external noise emissions of the tyre in decibels.

Since many people are unfamiliar with decibel values, the noise class is also shown. This categorizes the tyre in relation to European tyre noise limits.

  • 1 black wave: 3dB or more below the European limit
  • 2 black waves: between the European limit and 3dB below
  • 3 black waves: above the European limit

What the ratings mean

Decibel levels are measured on a logarithmic scale. This means that an increase of just a few decibels represents a big difference in noise levels. A tyre with a noise class of one black wave could be up to four times as loud as a tyre with three black waves.

Label values shown are for illustrative purposes only. Values for a certain tyre line/size may vary.
