A heavy-duty pneumatic tire includes a tread portion including a pair of shoulder land portions. At least one of the pair of shoulder land portions is provided with a narrow groove extending continuously in the tire circumferential direction to divide the shoulder land portion into a main portion and a sacrificial rib located outward in the tire axial direction. The sacrificial rib includes a root portion in a tire radial direction with an axial width Wr, a top surface in the tire radial direction with an axial width Ws, and a ratio Wr/Ws being equal to or more than 1.0. In the shoulder land portion, a shortest distance Lw between the narrow groove and a maximum thickness line that defines a maximum thickness of the shoulder land portion measured in a normal direction to a tire cavity surface is equal to or less than 5.0 mm.
