An Industry Viewpoint of Tire Sound Reduction and Measurement Methodology

The objective of the study of sound created by tires has been to provide a public record assessing factors affecting tire/pavement noise reduction. The tire industry supports the objective of reducing noise, and has worked toward this goal for many years. Once highways in this country became smooth enough, and vehicles quiet enough for the noise created at the tire road interface to be identified, tire designers began including noise reduction as one of the design characteristics to be considered. It is recognized that these sounds are something separate from all other vehicle noise which is heard along side of the road. Substantial achievements in reducing tire/pavement noise has been accomplished over the years.
