Vehicle costs for rock mass transportation are more than 50% of total costs, among which 25 — 30% are tire costs. The average tire life in mining enterprises is lower than that the value recommended by production plants. The tire life of open-pit dump trucks is more dependent on the normal load on the wheel. The main factor in the change of the normal load is location of the wheel on the dump truck and the open-pit road’s section. Determination of the maximum loaded tire in different operating conditions will allow increasing the tire life and preventing its premature failure. The TKPH index (tire performance) recommended by tire manufacturers does not take into account the diversity of mining conditions and variations of sections of open-pit roads on different routes. The average load per trip is defined as movement of a loaded open-pit truck and an empty open-pit truck on a straight reach of a road. The proposed method for recording of redistribution of the load on the wheel allows making adjustments to recording of TKPH indexes and thereby effectively managing the tire life, which in turn will make it possible to more fully use the tire life, increase its reliability and reduce the cost of rock mass transportation.
