Abstract. The aim of the study is to increase the efficiency of vehicle operation by establishing patterns of change in the performance properties of winter tires and improving, on this basis, methods for adjusting the frequency of their replacement. The research methodology is based on the application of a systematic approach, a number of private methods of the experimental-theoretical level and proven methods of processing experimental data.
As a result of the analysis of key factors, the relevance of the application of repair technology for studding car tires has been substantiated. Experimental studies on measuring the braking distance and acceleration time have confirmed the need for prompt diagnostics of the residual number of studs on car tires. It was found that the efficiency of the tire as the actual number of studs decreases non-linearly and depends largely on the type of road surface used.
The scientific novelty of the performed research is the regularities of braking and acceleration properties of cars operated on various road surfaces in winter conditions, taking into account the technical condition of studded tires.
The practical significance of such stands is to increase the demand for this service by reducing costs and significantly reducing labor costs associated with assessing the performance of winter tires. Technological operations using portable stands can be combined with periodic maintenance or carried out with a seasonal tire change both at service stations and in motor transport companies.
Further research is aimed at collecting, analyzing and systematizing data to establish the parameters of mathematical models of the most popular standard sizes of automobile winter tires, which will allow scaling the technology and reducing its cost due to mass use.
Thus, the results of the on-line diagnostics of tires can be used by car owners when making timely decisions about replacement or repair, which significantly increases traffic safety and reduces the cost of operation, since if the integrity of the tread is preserved, the restoration of winter tires with repair studs almost completely restores the original properties that determine numerical values of efficiency indicators at significantly lower costs in comparison with buying a set of new tires.
Key words: vehicle, anti-skid studs, pinching, wear, tire, coefficient of adhesion, stand for determining the number of studs.
