Abstract: The tyre plays an important role in the vehicle safety, while fatigue failure is the main mode of tyre failures. Based on a detailed review of the features and applications of current research approaches of tyre fatigue, crack propagation approach is a main one, in which, the rational determination of evaluation criteria is important to fatigue life evaluation. At the same time, analysis technique for tyre fatigue life prediction model is also a pressing technical problem. Based on the investigation of literature and theories of evaluation criteria used at present, it is pointed out that fracture energy criteria are more rational than other criteria for life prediction. After comparison of all analysis techniques presently used for building fatigue life prediction model, it is pointed out that the crack propagation approach, combined with fracture energy criteria with temperature effect taken into consideration, and adopting EDT analysis technique to build fatigue life prediction model, is an effective approach for analysis of tyre fatigue failure and prediction of tyre fatigue life.
