Vibrations of a tyre rolling on a road induce not only exterior noise by direct transmission through the air but also structural vibration and consequently interior noise of the attached vehicle. These vibrations structurally transmitted at the intersection between the tyre rim and the vehicle hub are one of the main causes of the relatively low frequency interior noise that becomes significantly disturbing when the vehicle approaches highway speed. The understanding of the transmissibility of forces from the tyre/ground contact surface area to the tyre hub is therefore an essential aspect of the reduction of interior noise. A semi-analytical model of the tyre belt and sidewalls has recently been developed for this purpose. Here, the prediction of forces transmitted from the tyre belt to a rigid rim using this model is discussed. The modelling predictions are compared to experimental measurements on actual tyres. Excellent agreement is seen up to about two hundred Hertz and good agreement until about four hundred Hertz.
