Abstract
PT. Freeport Indonesia, the largest underground mining company in Indonesia, faces a significant challenge with premature tire damage on its production units. This damage results in costly downtime and negatively impacts mine productivity. This research aims to identify the factors contributing to premature tire damage and analyze their impact on company expenditures. Using a quantitative research method and multiple linear regression analysis techniques, this study found that factors such as "Puncture steel" and "Running flat" have a negative impact on company expenditures. On the other hand, the factor "Rock cut" shows a positive impact on company expenditures. This research provides valuable insights for PT. Freeport Indonesia to develop more effective tire maintenance strategies, reduce downtime, and optimize operational costs.
