Abstract: The heavy duty tire comprises a belt layer 7 comprised of at least three belt plies outside of a carcass 6 in a radial direction. Belt cords of a first belt ply 7A disposed innermost in the radial direction incline at an angle of 45 to 55 degrees with respect to a tire equator C. Belt cords of second and third belt plies 7B, 7C disposed outside thereof incline at an angle of 16 to 22 degrees with respect to the tire equator C and into mutually opposite directions. Width BW3 of the third belt ply 7C is smaller than width BW2 of the second belt ply 7B and is also 77 to 95% of a tread grounding width TW. Width BW1 of the first belt ply 7A is smaller than the width BW3 of the third belt ply 7C by 20 to 35 mm. An inter-cord distance S between the first belt ply 7A and the carcass ply 6A in the tire radial direction is 0.8 to 1.2 mm.

Abstract: In a ground-contact surface shape of a tire, when a tangent angle formed between an axial direction of the tire and a tangent X at each point P on a profile line of the tire is defined as θ, a tangent angle θ1 in a ground-contact end point Pd is 25° or smaller. When a minimum value of the tangent angle θ in a region Y which is separated away from a tire equator C by a distance in a range of not less than 0.4 times but not more than 0.7 times a half of the ground-contact width of the tread is defined as θ2, and a tangent angle at a 0.9 times point Pq which is separated away from the tire equator C by a distance of 0.9 times the half of the ground-contact width of the tread is defined as θ3, a difference (θ3−θ2) is set in a range of not less than −10° but not more than +10°.

Abstract: A pneumatic tire which comprises a tread portion with a pair of tread edges, and a tire shoulder extending radially inwardly from one of the tread edges, provided with a curved surface comprising a convex curve, wherein, on a cylindrical surface centered on the tire axis and intersecting the curved surface, the convex curve swells axially outwards and has a curvature, and the curvature gradually diminishes towards the radially inside from the tread edge. It is possible that the tread portion is provided along the tread edges with a circumferentially extending rib and/or a circumferential row of blocks. In case of circumferential rib, the rib is provided with the curved surface comprising a plurality of the convex curves and a plurality of convex curves alternating therewith so that the curved surface is waved in the tire circumferential direction. In case of blocks in a circumferential row, it is preferable that each block is provided with the curved surface comprising at last one convex curve.
