In the motion performance of the vehicle considered in this study, the utilization ratio be-tween the camber thrust and the cornering force is dominant in the tire balance, with the centripetal force being an important element. In addition, it is necessary to examine the characteristics of both aspects of the human–vehicle system because they significantly affect the maneuvering capacities of the driver.

The orange bars represent the number of tires sent to repair, and the blue bars represent the amount of tires received from the repair facility, which is located about 800 km away from the mine site. The difference between the tires that were sent to repair and the ones that returned from repair is called the repair tire balance. If the repair tire balance is significant, it has the potential to negatively affect the availability of spare tires at the mine site, thus causing an inventory shortage. Alternatively, it can create an excess of used spare tires when they are not needed. The repair balance in 2018 is closer to zero in each season as compared to 2019. The main differences in the repair balance are observed in the spring and summer of 2019. As a result, 98% of tires were returned from repair and only one tire was scrapped; no impact could be observed in the spare inventory levels in 2018. On the other hand, 70% of tires were returned from repair in 2019, and the remaining tires were scrapped due to the effect of tire damage; this severely reduced the stock inventory in 2019.
