Modern trends in the development of car tires, in addition to the automation of the operation process, are also aimed at increasing their operational characteristics, one of the criteria that determines the state of tire behavior is tribological properties [1]. The indicated properties of the tire directly depend on its service life, fuel efficiency, and the comfort of the car, as well as traffic safety [2]. Therefore, the study of tribological properties of tires with the aim of further improving the efficiency of tires as a whole is currently a rather urgent task. The state of dynamic interaction in the "wheel-tire-road" system was studied, namely the car wheel rolling process, when its tire is subjected to deformation, which contributes to the creation of a moment of resistance to the rolling of the wheel and the actual adhesion of the wheel to the road. As a result of the research, ways to improve the tribological properties of car tires during movement are proposed.
