Abstract: Based on the application of set-pair analysis method and combining with maximizing deviation method to determine the weights，an evaluation model for the truck tire used in open pit is built. Here，twelve factors are chosen as the evaluation index，including road adaptability，climate adaptability，maximum load，maximum transport speed，barometric pressure，TKPH，tire rubber，service life，tread type，manufacturer credibility，after-sales service and tire price. Finally，through analyzing the open-pit mine，the model above is applied to assess the optional tire scheme to finally obtain the optimal solution which is consistent with the result from the correlation analysis. The case verifies the practicality and reliability of the model. 

Key words: Open pit mine, Truck tire, Maximizing deviation, Set-pair analysis
