Abstract A procedure is proposed for calculating the internal profile and optimal distribution of materials for a pneumatic car tire in a mold configuration. To adequately describe the elastic-dissipative properties of tire rubbers and rubber-cord composites, nonlinear elastic deformation Mooney–Rivlin model and viscoelastic Prony model as well as experimental data of static and dynamic tests are considered. An algorithm for finite element analysis of the stress-strain state of a passenger car tire is described in the MSC.Marc software package, and results of numerical solution of applied problems are presented on the tire landing on the rim and its loading with working pressure, as well as on the contact interaction of a passenger car tire with the road surface at maximum operating load at rest and during stationary rolling at a speed of 90 km/h. It was found that the contact loading of the tire when interacting with the road surface does not lead to a significant difference in the deformed state in the zone opposite diametrically to the contact zone from that for a tire mounted on a rim and loaded with excess operating pressure. In this case, the nature of the distribution of strains in the radial section near the contact zone of the tire with the road surface is the same under conditions of compression and stationary rolling. Areas of concentration of equivalent stresses and strains in the bead zone of the tire and in the zone of the edges of the breaker are revealed. For a quick comparison of competing tire designs, it is recommended to calculate the average values of the total strain energy density per wheel revolution. The developed calculation methods make it possible to predict the performance characteristics of automobile tires at the design stage and are tested in the manufacturing of these products.
