A model of automobile rotating tyre is constructed by the Finite Element Method using the truncated conical shell element based on the first-order shear deformation theory. And in order to investigate basically the characteristics of tread pattern excitation sounds, the influences of tread pattern pitch number and pattern arrangement on the vibrations of tyre surface are examined by approximating the pattern exciting mechanism by the sinusoidal contact pressure loading from the earth. As a result, it turns out that the vibration amplitude of tyre decreases as the number of pattern pitch increases and besides the pattern becomes stagger-type for almost all automobile running speeds. And as to the distribution of tyre surface vibration amplitudes for the circumferential direction, the vibration amplitudes become remarkably large at the parts of the trailing and leading edges.
