A heavy duty tire includes a tread (1) configured to come into contact with a road surface. The tread has a block-shaped land portion (12) having blocks (18) aligned in a circumferential direction and having a lateral groove (16) between adjacent blocks. Circumferential grooves (10) are located on both sides of the block-shaped land portion (12), and are each an irregular circumferential groove having a non-flat groove wall. The lateral groove (16) is shallower than the irregular circumferential groove (10). An opening of the irregular circumferential groove (10) includes a pair of edges (14) extending straight or in a zigzag or wavy manner. A virtual opening of the irregular circumferential groove (10) obtained by virtually cutting the tread along a plane including a groove bottom of the lateral groove (16) includes a pair of virtual edges (24) extending in a zigzag or wavy manner. An amplitude of each virtual edge (24) is larger than an amplitude of each edge(14), and a number of the virtual peaks included in the virtual edge (24) is larger than a number of the lateral grooves (16) included in the block-shaped land portion (12).
