The automakers are continuously interested in NVH solutions for high quality vehicles. The dynamics of a tire, which is excited mainly from the road, is under observation. In this paper the modal parameters of an inflated tire are determined by using finite element analysis. The natural frequencies and the modal vectors of the prestressed structure for a couple of pressure values are presented. The pressure influence on the natural frequencies can be assessed. Further studies will observe the experimental modal analysis and the frequency response analysis of the structure.
