The comfort of vehicle has increased in importance in recent years. The comfort of the vehicle is highly dependent by the vibrations from the road surface, such as through the tire and suspension. vehicle wheels are expected to have a major effect on the vibration characteristics of the vehicle tire. In this paper, compare the vibration characteristics of the special purpose wheels with FRF method and FEM method using the finite element model. And the natural frequency changes of using FEM according to tire pressure changes. Results show that natural frequency is changed by tire pressure change.
