The invention discloses a tire life prediction method and device, equipment and a storage medium, and relates to the technical field of tire detection, and the method comprises the steps: obtaining a finite element calculation result of a global model corresponding to a target tire and tire material parameters representing fatigue; performing life prediction on the target tire based on the finite element calculation result and the tire material parameters to obtain an initial prediction result corresponding to the global model; determining a target area meeting a preset tire life weak condition from the global model according to the initial prediction result, and constructing a corresponding sub-model based on grid information corresponding to the target area; and carrying out life prediction on the corresponding target area by utilizing the deformation gradients and stress data of the sub-models at different moments so as to finally obtain a target prediction result corresponding to the target tire. In this way, the precision degree of tire life prediction can be optimized, and the accuracy of tire life prediction is improved.
