Vehicle tires are expensive products and have a relatively small resource. The operating costs of a tire for specialized vehicles operating in quarry conditions are up to 20% of the amount of transportation costs. On the basis of experimental and theoretical studies of tire wear resistance of specialized vehicles, an original method of standardizing tire mileage, taking into account work in quarry conditions, has been developed. In the classification of operating conditions, an additional assessment of the road surface D7 - intra-quarry and dump roads was introduced. For the first time developed and introduced into scientific circulation coefficients for correcting the mileage of tires of specialized vehicles Kgp, depending on the category of rock strength on the scale of prof. M.M. Protodyakonov, on the basis of which career roads were laid. Linear correlation analysis of the Kgp and f coefficients showed that they have a strong negative correlation - according to Pearson's criterion -1, which confirms the correct choice of tire mileage correction coefficients depending on the breed category.
