ABSTRACT:
A heavy-load radial tire, comprising three or four belt layers of steel cords laminated at a slight angle with respect to the tire circumference direction in the central part of the outside of a carcass. An intermediate belt layer adjacent to the outermost belt layer has a cord strength which is at least 1.2 times greater than that of an inscribed belt layer which is inscribed in said intermediate belt layer. The end number of the intermediate belt is reduced so that the belt strength of the intermediate belt layer is substantially equal to that of the inscribed belt layer.
