Presentation

Improving the EU tire noise label

The STEER (Strengthening The Effect of quieter tyres on European Roads) project was launched with the purpose of improving the EU tire noise label. This presentation will cover some of the results and proposals of the project. Although it deals with the European tire label, it should be equally relevant for tire labels in other parts of the world. Within a related project, 53 tires from 3 tire lines were tested for noise emission and their results compared with the labeled values. It was found that tires with the same label can differ up to 6dB in measurements.
