ABSTRACT:
A heavy duty pneumatic radial tire comprises a radial carcass, a main cross belt and a tread portion, in which the main cross belt is formed by laminating at least three rubberized cord layers so that the cords in each layer are parallel to each other but the cords between the adjoining layers are crossed with each other and extend in opposite directions with respect to an equatorial line of the tire. In such a tire, a pair of cushion rubbers are arranged between the adjoining rubberized cord layers constituting the main cross belt at their both end portions by setting a position relation between mutual cushion rubbers at both belt ends to an optimum value to thereby prevent or control the occurrence of the belt end separation failure.
