A heavy duty pneumatic tire includes a tread, a pair of side walls, and a belt. The tread includes a base layer and a cap layer on the base layer such that boundary between the base layer and the cap layer is exposed on the side surfaces of the tread and the boundary on the side surfaces is on radial direction inner side of the edges of the side walls, and the tread is formed such that when an imaginary line passing through edge of the belt and extending in axial direction is set and a portion of the imaginary line intersecting the tread is a line segment AL, a ratio of width of the base layer in width of the tread is 70% or more where the width of the tread is length of the segment AL, and the base layer has a loss tangent of 0.06 or less.
