Tire/road noise, also called rolling noise, is an important part of vehicle noise. The mechanical interactions between tire pattern and the road asperities is a major contributor to mechanisms at the origin of tire/road contact noise. This paper presents an experimental study of the dependence between the dynamic contact forces and the rolling noise. A measurement campaign was carried out on asphalt pavement samples to achieve this aim. It is found that the mean value of the normal contact force, responsible of the rolling noise, remains constant and the level in dB of this force increases linearly with the logarithm of the rolling speed.
