Since 2012 all new tires in Europe must be labeled. The label contains general information about tire performance concerning rolling resistance (that corresponds to fuel economy), noise emission and wet grip (only for passenger car tires). Measurements of noise performance of tires must be performed according to the Annex 3 of the Regulation No 117 of the Economic Commission for Europe of the United Nations. The regulation specifies pass-by method of tire/road noise measurements with vehicle tires rolling on the reference surface built according to the standard ISO 10844. The paper presents results of tire/road noise measurements performed at the Technical University of Gdansk for tires with different noise labels and discusses correlation between data stated in the labels and measured noise levels. The measurements were performed by CPX and drum method on different road surfaces or on replica road surfaces. ISO specified surface is not very typical for European road network so ranking of tires obtained on this surface may or may not be representative for real life applications.
