The article presents the results of calculating the performance of tires. It is substantiated that in quarry operating conditions, the determination of the actual tonne-kilometers per hour (TKPH) is an important criterion for tire performance. Due to the fact that tire manufacturers (Michelin, Belshina, Goodyear, Bridgestone) give different correction factors (K₁, K₂) to calculate the actual TKPH, the following correction factors (K₃) TKPH have been developed depending on the hardness of the rocks laid as surface of open pit roads: for JSC “Almalyk MMC” K₃=1.15, for JSC “Kizilkumcement” K₃=1 and for JSC “Uzbekugol” K₃=0.8.
