Evaluation of the effect of off-the-road tire air pressure setting on tire performance

This study presents analysis on the effect of tire air pressure setting at installation on tire life and wear rate. Also a look into the tire spike air pressure is conducted. The relevant data were collected from the Kemess Mine. An engineering statistical method-analysis of variance (ANOVA) is employed to determine and quantify the installation air pressure setting influence on tire life and wear rate. The quantitative results indicate the tire life and wear rate are influenced by higher installation air pressure settings. In addition, the wheel positions that have experienced most spike air pressures are identified.
