Abstract
The paper presents the results from CPX measurements of tyre/road noise performed for selected passenger car tyres, including the tyres especially designed for electric vehicles. The tyres have been measured when rolling on several typical road surfaces in Norway and in Poland. In addition, the tyres have been measured on some very low noise road surfaces, such as a the poroelastic road surface (PERS). The measurement results show that there is a potential reduction of tyre/road noise of 5-7 dB, when using optimized tyres for electric vehicles in combination withof a low noise porous surface. Introducing a poroelastic surface, the noise reduction potential is even higher; : 10-12 dB. On the Norwegian road surfaces, only two tyres developed for electric vehicles have been measured. However, one of these tyres proved to be the quietest on most surfaces, approximately 2 dB below the average.
