<p>A heavy duty pneumatic radial tire comprises a radial carcass extending between a pair of bead cored, and a belt comprised of three rubberized cord layers, among which cord layers an innermost cord layer and a middle cord layer being laminated to form a cross belt layer by crossing cords of these cord layers with each other with respect to a plane including a circumference of the tire, in which an inclination cord angle with respect to said plane in the innermost cord layer and the middle cord layer is within a given range, and cords in an outermost cord layer have a given inclination cord angle as measured from said plane toward a direction of measuring the inclination cord angle of the middle cord layer, and a coating rubber for the outermost cord layer has a given modulus of elasticity. <IMAGE></p> |
