A heavy load pneumatic tire comprising: a carcass; and a belt, in a tread portion, positioned outward from the carcass in a tire radial direction, wherein the belt includes an intersecting belt layer formed by layering a pair of belt plies, belt cords in the belt plies intersecting each other with a tire equatorial plane therebetween, and an angled belt layer formed by at least one belt ply, 14° < θ 1 < 20° and 15° < θ 2 - θ 1 < 20°, where θ 1 is an angle, with respect to the tire equatorial plane, of the belt cords in the belt plies forming the intersecting belt layer, and θ 2 is an angle, with respect to the tire equatorial plane, of a belt cord in the belt ply forming the angled belt layer, in a cross-section in a tire width direction, the carcass has a shape, from an outermost position of the carcass in the tire radial direction to an outermost position of the carcass in the tire width direction, formed by connecting two arcs with a center of curvature towards an inside of the tire and with different radii of curvature, R 1 > R 2, where R 1 is a radius of curvature of an inner arc positioned inward in the tire width direction and R 2 is a radius of curvature of an outer arc positioned outward in the tire width direction, and a distance (D i), measured along the tire width direction from the tire equatorial plane, to an intersection of the inner arc and the outer arc is from 80% to 105% of a distance, measured along the tire width direction from the tire equatorial plane, of a range of overlap between the belt plies in the intersecting belt layer. a carcass; and a belt, in a tread portion, positioned outward from the carcass in a tire radial direction, wherein the belt includes an intersecting belt layer formed by layering a pair of belt plies, belt cords in the belt plies intersecting each other with a tire equatorial plane therebetween, and an angled belt layer formed by at least one belt ply, 14° < θ 1 < 20° and 15° < θ 2 - θ 1 < 20°, where θ 1 is an angle, with respect to the tire equatorial plane, of the belt cords in the belt plies forming the intersecting belt layer, and θ 2 is an angle, with respect to the tire equatorial plane, of a belt cord in the belt ply forming the angled belt layer, in a cross-section in a tire width direction, the carcass has a shape, from an outermost position of the carcass in the tire radial direction to an outermost position of the carcass in the tire width direction, formed by connecting two arcs with a center of curvature towards an inside of the tire and with different radii of curvature, R 1 > R 2, where R 1 is a radius of curvature of an inner arc positioned inward in the tire width direction and R 2 is a radius of curvature of an outer arc positioned outward in the tire width direction, and a distance (D i), measured along the tire width direction from the tire equatorial plane, to an intersection of the inner arc and the outer arc is from 80% to 105% of a distance, measured along the tire width direction from the tire equatorial plane, of a range of overlap between the belt plies in the intersecting belt layer. 14° < θ 1 < 20° and 15° < θ 2 - θ 1 < 20°, where θ 1 is an angle, with respect to the tire equatorial plane, of the belt cords in the belt plies forming the intersecting belt layer, and θ 2 is an angle, with respect to the tire equatorial plane, of a belt cord in the belt ply forming the angled belt layer, in a cross-section in a tire width direction, the carcass has a shape, from an outermost position of the carcass in the tire radial direction to an outermost position of the carcass in the tire width direction, formed by connecting two arcs with a center of curvature towards an inside of the tire and with different radii of curvature, R 1 > R 2, where R 1 is a radius of curvature of an inner arc positioned inward in the tire width direction and R 2 is a radius of curvature of an outer arc positioned outward in the tire width direction, and a distance (D i), measured along the tire width direction from the tire equatorial plane, to an intersection of the inner arc and the outer arc is from 80% to 105% of a distance, measured along the tire width direction from the tire equatorial plane, of a range of overlap between the belt plies in the intersecting belt layer.
