This report examines the noise produced by the action of lorry tires rolling on road surfaces and attempts to identify both the main sources and the mechanism of noise generation. A parametric study showed the rolling speed of the tire was the main factor affecting the overall levels of tire noise. Other factors of importance were wheel loads, tire tread and road surface pattern, tire construction and materials, acoustic absorption by the road surface and the presence of surface water. The study of sources established tire surface vibration as the main source of tire noise and other sources including 'air pumping' and aerodynamic noise were not found to contribute significantly to the overall levels on conventional road surfaces. Tire vibration was found to be associated with the slip of the tread elements in the contact zone, the degree of slip being, largely, controlled by the frictional adhesion between the tire and the road surface and the deformation of the tire tread.
