Estimation of tire wear and traumatic event intensities

A tire wear model including dependence of the distribution of the traumatic failures of various modes on the wear is proposed. Non-parametric, semi-parametric and parametric methods of estimation for the main reliability characteristics of tires are given. The model makes it possible not only to estimate unconditional functions such as the survival function and the mean failure time of tires and the probabilities of failures of the particular modes, but also to predict residual characteristics such as the probability of survival given the run and the wear of a tire, to estimate the ideal reliability characteristics and to predict reliability of tires when causes of the particular traumatic failure modes are eliminated. Analysis of the real failure time and degradation data of tires is given.
