摘要： A heavy-duty pneumatic tire includes a carcass including a carcass ply extending from a tread portion through a sidewall portion and turned up around a bead core of a bead portion. The bead core includes a radially inner surface extending along a bottom surface of the bead portion in the radial direction of the tire. Under both conditions that include an unloaded standard condition where the tire is mounted on a standard rim and inflated to regular internal pressure and a loaded standard condition where the tire in the unloaded standard condition above is loaded with a regular load and grounded at a camber angle of 0 degrees, the tire has an angle between the radially inner surface of the bead core and a rim sheet surface of the standard rim being in a range of 0 plus/minus 3 degrees.
