This work describes a statistic analysis of the service life of tires applied in off-highway trucks used in open-pit mining. Understanding the process of occurrence of structural failures, correlated to the fatigue mechanism and often observed in mechanic components, is of vital importance for the current industry. Since these failures usually happen suddenly, understanding them in the most diverse components submitted to cyclic loads helps analyzing the material’s progressive deterioration along time; it acts as a return to potential improvements in the product, giving feedback of computing simulation data; and it potentially increases operational safety by mitigating the consequences it has on the productive process and on the people exposed to such failures. The tires, components that integrate great part of the on wheels vehicles fleet - amongst them: transportation equipment, industrial mobile equipment and mining equipment - are inserted in this context.
