Problem. In the scientific and methodological recommendations of forensic institutions and in the scientific and technical literature there are currently no universal methods for determining the braking parameters of cargo multi-axle vehicles that have wheels with double tires, which affects the results of drawing up the conclusions of the motor-technical expertise. The lack of universal methods is due to the difficulty of determining the actual braking, especially when the tires of dual wheels interact with the road surface. Goal. The goal is justification of the method of determining the average torsional stiffness of tires of a double vehicle wheel during its interaction with the road surface. Methodology. The approaches adopted in the work to achieve the set goal are based on the theoretical foundations of the deformation of elastic elements, which are located parallel to each other. Results. Equations are determined that allow you to calculate the value of the average torsional stiffness of
the tire for wheels that have double, triple or quadruple tires. Originality. The results of the research
provide a general idea of the effect of the pressure in the tires of a double wheel on the value of its
average torsional stiffness. Practical value. The obtained results can be recommended to expert motor
technicians when drawing up a conclusion of an expertise or an expert study. Besides, the results of
the study can be used in the educational process during the training of specialists in the field of
transport or mechanical engineering.
