Provided is a heavy load pneumatic tire for construction vehicles that can not only further enhance the wear resistance of the land portion in the central region of the tread surface and the land portions in the side regions, but also effectively prevent heat damage at the central region of the tread surface. Side lug rows (7) are provided at both side regions of a tread surface (1) and are formed by a plurality of lugs (6) defined by lug grooves (5) opening to edges in the tread width direction, and a central block row (4) aligned on the tire equator (E) and formed by a plurality of blocks (3) is disposed between positions at 1/4 of the tread surface width (TW) from the tire equator. The tire has a directional tread pattern, with a designated rotation direction, formed by circumferential grooves (8) and width direction grooves (9) that define the blocks (3) of the central block row (4) and are narrow grooves with a narrower groove width than the lug grooves (6). The distance (HS, HE) from the tire equator (E) to the groove wall in each of the circumferential grooves (8) defining the blocks (3) is set to be larger at a leading edge (10) of each block (3) than at a trailing edge (11) of each block (3).
