description The invention discloses a tire durability simulation analysis method and a tire. The method specifically comprises the following steps: at least obtaining the fatigue life and strain energy density amplitude of a tire bead rubber material; and according to the fatigue life and the strain energy density amplitude, fitting to obtain a fatigue life prediction method of the tire bead rubber material. A structural sensitivity analysis model is adopted, the strain energy density amplitude of the tire bead rubber material serves as a fatigue analysis evaluation index, and tire bead fatigue durability factors are analyzed and generated; building a Kriging approximation model of the fatigue durability factor of the tire bead and the maximum strain energy density amplitude; and improving the tire bead rubber material structure according to the fatigue life prediction method and the Kriging approximation model. According to the tire durability simulation analysis method and the tire, the problems that in the prior art,
