Abstract : Tire vibrations are partly responsable of acoustic nuisance related to tire-road contact noise. We analyse tire vibrations measured by an accelerometer fixed to the tire of a car, both by means of classical spectral analysis Fourier transform and by time-frequency analysis Wigner-Ville distribution. We point out distinct behaviours when the tire is excited by the road texture or by the tire tread pattern.
