This paper presents a new experimental modal parameter estimation method to be applied to point symmetric structures, and shows an application to modeling of tires for passenger-cars. The method decomposes frequency response functions into the components of individual natural modes based upon Fourier transform algorithm in the circumferential direction of spatial domain at first, and then determines the modal parameters using the components of each natural mode. In this paper, we explain the theory of the method, and present a challenging application of the method to an actual tire for passenger-cars. The tire is experimentally identified about its dynamic characteristics under the free-free boundary condition, and the result of the identification is expressed as a set of spatial matrices. The number of degrees of freedom of the identified spatial matrices is 152. Finally, in order to demonstrate the validity of this model, we carry out a prediction analysis of the tire under a clamping boundary condition, and compare the result with experiment.
