✦ Synopsis

A one-dimensional wave equation of an in"nite #attened tyre belt is generated. The belt vibration is controlled by bending, tension, shear and the sidewall sti!ness. The dispersion relations for two waves in the belt are calculated and used to "nd both the input impedance and attenuation on a tyre belt of in"nite extent. Tension and the sidewall controls the deformation and sti!ness below 100 Hz. Waves propagate around the belt above this frequency. The wave speeds due to bending and shear were predicted and measured. The model presented here should be valid for the prediction of tyre response above about 400 Hz when for a car tyre the modal behaviour is observed to cease. In this high-frequency region, the tyre at the input appears to be of in"nite extent.
