A numerical method is described for computing tyre vibrations over a large frequency range. It is based on a recursive finite element method for building the dynamic stiffness matrix of a complete tyre from the knowledge of a finite element model of a small part of the structure. The present method is compared to full three-dimensional finite element solutions showing a perfect agreement for low frequencies. However, this method allows computations for medium and high frequencies which are needed for the analysis of noise generated by a tyre. The influence of various parameters on the frequency response functions like the positions where the responses are computed, the mechanical parameters of the tyre or the internal air-pressure are described.
