The invention discloses an all-steel radial tire which comprises a tire body, a tire core and a tire core, the lining layer is arranged on the inner side of the tire body; the belt ply is arranged on the outer side of the tire body, and the belt ply is used for hooping the tire body; the reinforcing layer is arranged at a tire shoulder inside the lining layer, the reinforcing layer is used for fixing the tire shoulder of the lining layer by adding an angled cord thread reinforcing layer bound at the tire shoulder, the first cavity is filled with shoulder pad rubber, and the second cavity is filled with pad rubber. The angle of the first belted layer is 40-70 degrees; and the angles of the second belted layer, the third belted layer and the fourth belted layer are all 15-25 degrees. The reinforcing layer is a cord thread reinforcing layer, and the angle of the cord thread reinforcing layer ranges from 15 degrees to 30 degrees. The shoulder stress of the tire crown is improved, the shoulder rigidity of the tire crown is improved, and the problems of groove cracks, shoulder cracks and line exposure are avoided.
