Some of the pass-by noise a car makes comes from the tires. By choosing a tire with a good noise rating you can lower the impact of your driving on the surrounding environment.
What does the EU noise rating measure?
The EU rating measures the external noise emissions of the tire in decibels.
Since many people are unfamiliar with decibel values, a loudspeaker image with black waves is shown to signify how noisy the tire is. The more waves there are, the louder the tire.
- 1 black wave: Quiet (3dB or more below the European limit)
- 2 black waves: Moderate (between the European limit and 3dB below)
- 3 black waves: Noisy (above the European limit)
What do 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. In fact, a difference of 3dB doubles the amount of external noise the tire produces.
Think about the many thousands of cars on our roads each day. If we all chose tires with lower noise ratings, imagine how much quieter our towns and cities would be.
