Abstract
In a heavy duty radial tire, a reinforcement belt outward in a radial direction of the tire and a high-strength belt inward in the radial direction are arranged between a radial carcass and a tread rubber , and an intersect angle between cord of an innermost wide-width slant cord layer in the reinforcement belt and cord of an outermost narrow-width slant cord layer in the high-strength belt is not less than 10° at an acute angle side, and narrow-width slant cord layers of the high-strength belt in the tire mounted onto a rim and inflated under a maximum air pressure have a width corresponding to 20˜60% of a ground contact width of the tread rubber , and inclination angles of cords with respect to an equatorial plane of the tire are not more than 15°, and a rubber gauge t of a first rubber layer between cord of an innermost wide-width slant cord layer and cord of an outermost narrow-width slant cord layer is 0.9˜3.0 times a cord diameter D of the slant cord layer
