Provided is a heavy load tire that includes a pair of bead portions and a carcass extending toroidally between the pair of bead portions. The heavy load tire, on an outer circumferential side of a crown region of the carcass, includes: the first belt layer including a cord extending in the tire circumferential direction; the second belt layer including a cord extending to be inclined with respect to the tire circumferential direction; and the third belt layer including a cord extending to be inclined at an angle of 30° or less with respect to the tire circumferential direction in a direction opposite to that of the cord of the second belt layer. The first belt layer, the second belt layer, and the third belt layer are arranged in the stated order from the inner side to the outer side in the tire radial direction. The third belt layer has a width w 3 that is 80 % or more of a tread width w , and the second belt layer has a width w 2 . The width w 2 and the width w 3 satisfy the relation w 2 < w 3 . |
