Companies are increasingly seeking methods to eliminate costs, and one of the big problems in companies is rework. The objective of this study was to identify costs and rework through the application of quality tools, allied to the Monte Carlo method (MMC), comprising the productive process of tire retreading, through an exploratory study. The applied methodology was in a tire retreading industry, located in the southern Fluminense region, in the state of Rio de Janeiro. One can conclude from the use of quality tools that the main failures within the process were the vulcanization, bonding and scarification / repair and also analyze by the Monte Carlo method the costs presented in the tire reform process through 5000 interactions. Through the tools, we can quantify the failures occurred in each stage. The main contribution of this work is the identification of the costs caused by the rework in the tires of automobiles and of load.
