A sipe (110) extended in a tire width direction is formed in a block (100) of a heavy load pneumatic radial tire. An inclined portion (120) is formed on an end portion at a kick-out side of the block (100) defined by the sipe (110). The inclined potion (120) is formed by chamfering the end portion at the kick-out side so as to be inclined inward from an outer side in the tire radial direction to an inner side in the tire radial direction. The inclined portion (120) is formed at least in a region where the crossing belt layer is formed, in the tire width direction.
