The invention relates to the calculation field of a tire carcass safety factor of an all-steel radial tire, especially relates to a calculation method of the tire carcass safety factor of the all-steel radial tire through tire material models and a finite element analysis technique. The calculation method of the tire carcass safety factor of the all-steel radial tire uses self-developed simulation model software to build material model diagrams of the all-steel radial tire with different specifications and calculates a tire carcass structural safety factor of the all-steel radial tire through the finite element analysis.
