Exterior noise

Buying truck or bus tires with a good noise rating will lessen the impact of your vehicle on the environment around you.

The tire’s exterior noise level is shown as a decibel value. The sound wave icons indicate if the tire noise is below or above European limits.

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)

Decibels matter

An increase of just a few decibels represents a large difference in noise levels. A tire with a noise class of three black waves could be up to four times as loud as a tire with one black wave.

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