Research on tire performances has been continuously receiving much attention with the rapid development of the automobile and airplane industries. Various approaches have been developed for the analysis of tire vibration and their dynamic response. An efficient numerical approach is presented to predict the vibration frequencies of a radial tire. Bezier polynomials for the displacement fields are used as the trial functions of the Ritz procedure. It is demonstrated that the present approach is accurate and effective for computing vibrations of tires. When compared with the methods of three-dimensional Solid-FEM and Shell-FEM, the present approach can save much CPU time because of the fewer variables in use. From the numerical solutions with different inflation pressures, tread mass, and ply-angles, it is shown that these physical parameters have much influence to the vibrations of tires. Structure designs of tires can be guided by the present analysis. The present method will be further applied to the analysis of footprint of the tire/road interface and dynamic problems of tires.
