✦ Synopsis
The static and dynamic sti!ness of a tyre sidewall are calculated as a function of geometry, load parameters and frequency. Two di!erent expressions were used for below and above the ring frequency. The air pressure and section aspect ratio are found to be the controlling in#uences below the ring frequency. This sidewall sti!ness was inserted into previously obtained wave equations to obtain the dispersion relationships and impedances for a tyre belt with sidewalls. The sti!ness and force transmission to the hub in the region of the contact patch was also calculated and compared with measured values. The sidewall sti!ness in the region of the contact patch is found to be strongly dependent on the belt wavespeed, giving a sti!er value in the region of the contact patch above the ring frequency.
