Summary:

The CPD (Contact Pressure Display) method allows simultaneous recording of pressure distribution between a flexible body and a quasi-rigid one. The light reflected from a special sandwich plate produces an interference pattern function of the contact pressure distribution. The method, used until now for determining human foot-ground pressure patt rn, during gait, was adopted to analyze several passenger car tires. Processing the measurements through a simple technique allows the determination of realistic tire contact pressure diagrams, taking into account the influence of the tread pattern. Several results are presented. The method may yield important data to be used as boundary conditions in numerical models of tire behavior, for static and dynamic tire design. It seems that it is possible to use the CPD method in detecting tire defects, by analysing the differences in pressure distribution. Other possible utilizations are non-destructive road test stations for truck tires, non-destructive evaluation of racing car tires
