Truck fleet tires reliability analysis and cost reduction methodology

This paper establishes a methodology for evaluation of the useful life of radial tires used in fleet vehicles, using removed product failure classification and removal time obtained after scrap tire analysis. In the evaluation of the reliability of products, non-parametric and parametric analyses using Weibull distributions are carried out in order to identify and characterize which failures cause higher financial loss in fleets. Comparing the losses due to early failures it's possible to prioritize countermeasures for scrap reduction that present more efficient results.
