This article presents a methodology for studying the effect of each percentage of the longitudinal slope of open-pit roads on tire life. The experiment was carried out at the Muruntau quarry, owned by the Navoi Mining and Metallurgical Combine (NMMC). The experiments were carried out on Komatsu HD785-7 dump trucks with a carrying capacity of 91 tons. According to the results of the experiment, it was found that the life of dump truck tires operated on routes with an average road slope of 6% is reduced by 2 times compared to tires operated on a horizontal road.
