  "textContent": "To provide a heavy duty pneumatic tire 2 that allows reduction in rolling resistance to be achieved while allowing influence on various performances to be suppressed. In the tire 2, side walls 6 respectively extend from side surfaces 30 of a tread 4 substantially inward in a radial direction. The tread includes a base layer 64 and a cap layer 66. A boundary 68 between the base layer 64 and the cap layer 66 is exposed on the side surfaces 30 of the tread 4. The boundary 68 on the side surfaces 30 is positioned on a radial direction inner side of edges 70 of side walls 6. When an imaginary line that passes through an edge of a belt 14 and extends in an axial direction is set and a portion of the imaginary line that intersects the tread 4 is a line segment (AL), a ratio of a width (BL) of the base layer 64 in a width (EL) of the tread 4, which is represented by a length of the line segment (AL), is 70% or more. The base layer 64 has a loss tangent (TLb) of 0.06 or less.",
