Abstract
A heavy duty pneumatic tire includes a tread portion including a plurality of blocks separated by a plurality of circumferentially extending main grooves and a plurality of lateral grooves. At least one of the blocks is provided with two axially extending sipes to divide the block into a first end portion, a second end portion and a middle portion between the first end portion and the second end portion. The first end portion includes a first projected portion that protrudes outwardly in a block-width direction from the middle portion so as to form a steplike side, and the second end portion includes a second projected portion that protrudes outwardly in an opposite block-width direction to the first projected portion from the middle portion so as to form a steplike side.
