Tire Noise Regulations-Technical and Economic Implications 762033

Operational noise emission standards are presently in effect for interstate motor carriers. Point-of-sale noise standards for medium and heavy duty trucks have been promulgated with an effective date of January 1, 1978. Although “fixes” have been demonstrated for most of the engine-related noise sources on trucks, tire noise remains an unsolved problem at highway speeds. If community noise levels are to be reduced near highways, tire noise must also be reduced. This paper reviews the operational and design variables affecting tire noise and investigates the technical and economic factors associated with current tire use practices and with revisions to these practices which may be necessary to comply with future tire noise regulations.
