For most of the modern passenger cars tire noise is dominating the external noise emission for constant speeds above approximately 40-50 km/h. This means that for freeflowing traffic a reduction of tire noise is necessary in order to achieve an improvement in traffic noise. Recent studies have pointed out that the type of road surface can influence tire noise as much as, or more than the type of tire. This indicates that a possible way to significantly reduce tire noise is to influence the choice of the road pavement.
