The invention relates to the technical field of tire manufacturing, in particular to an all-steel radial tire bead which structurally comprises a lining layer, reinforcing nylon, a cord layer, a 1 # reinforcing steel wire, a lower apex rubber core, an upper apex rubber core located above the lower apex rubber core, a steel wire ring located below the lower apex rubber core, a cord layer, a 2 # reinforcing steel wire, sidewall rubber and seam allowance wear-resistant rubber. Sidewall rubber; and 2 # reinforcing steel wires are added among the outer side end points of the reinforcing steel wires, the outer side end points of the cord thread layers and the nylon reinforcement. The heavy-load tire bead structure of the all-steel radial tire is higher in tire bead rigidity and more reasonable in material gradient distribution, the durability of the tire bead of the tire is improved, the service life of the tire under the high heavy load condition is prolonged, and the problems that the anti-wrapping end point of a
