The presented model is valid below the cut-on of the first treadband axial bending mode; unlike most ring models that are limited to in-plane modes only. The fully assembled tyre model includes a wheel and air cavity model, which is necessary to describe all physical phenomena in the frequency range of interest. This makes the model suitable for the prediction of structure borne interior tyre/road noise. The parametrization of the model is based on simple geometrical properties of the tyre and the experimental modal parameters of three tyre modes. Despite the drastic, well considered simplifications, comparison between measured and calculated responses shows that the tyre-wheel model describes the dynamic behaviour with acceptable accuracy. Since the model is physical, it can also be applied to predict the dynamic behaviour under different operating conditions, such as loading and rotation. In this paper the loaded tyre response is calculated and validated.
