The invention relates to an all-steel radial tire, in particular to an all-steel radial tire with an improved tire shoulder rubber pad structure. The all-steel radial tire using two compounded rubberpads comprises the rubber pads, 1# belted layer end points, a 2# belted layer, tire body curtain cloth, a tire surface, a tire side and a tire body, the rubber pads comprise an upper rubber pad and alower rubber pad; the upper rubber pad is positioned on crown parts of the 1# belted layer end points, below the 2# belted layer and above the tire body curtain cloth; the lower rubber pad is positioned among the tire surface, the tire side and the tire body; and 300% extension modulus in the physical property of the upper rubber pad is greater than that of the lower rubber pad, the elongation ofthe upper rubber pad is smaller than that of the lower rubber pad, and the shore hardness of the upper rubber pad is greater than that of the lower rubber pad. The two compounded rubber pads are connected with the tire surface,
