Abstract

Studies have been made of the factors involved in tire/road noise with a view to reducing the intensity of the total noise level by modification of both the tire tread pattern and the materials used for road surfaces.

The work covers test results on automobile tires over a wide range of road surfaces, and includes testing of automobile tires on indoor replica road surfaces, to separate the surface-excited and the tread pattern-excited components.

Figures relating noise level in dry conditions to braking grip in wet conditions show that it is possible to increase wet grip and still reduce noise level by using suitable road surface materials.
