The article provides substantiation for the possibility of diagnozing latent damage to car tyres by comparing the average value of the static tyre rate at different points. The degree of uneven static stiffness of the tyre along its circumference was estimated by the size of the tyre contact spot with the support surface. An original method for approximate determination of the tyre spot area contacting with the supporting surface is proposed. The results of determining the area of the tyre contact spot at various points with several values of air pressure in the tyre are presented.
