The effect of tire aging on acoustic performance of CPX reference tires

Abstract

Reduction of tire/road noise is one of the biggest environmental challenges of road traffic. To reduce that noise it is necessary to perform acoustic measurements on the base of wellproven standard procedures. One method of measurements that is in common use, namely the Close Proximity Method (CPX), is described in standard ISO-DIS 11819-2. As this method is used to classify road surfaces regarding their influence on vehicle noise, it requires the tests to be carried out using reference tires that ensure representativeness of the results and their comparability between different teams making measurements. The draft standard ISO/TS 11819-3 describes the reference tires for CPX method. This paper discusses some issues related to the reference tires, such as the effect of aging on the tire hardness and noise and presents the results of noise measurements performed for several nominally identical items of the reference tires designated as "P1" and "H1" in the standard. It is considered that CPX reference tires may be also nominated as reference tires for testing of the tire rolling resistance.
