Pneumatic Tire

A pneumatic tire comprising:

• a pair of bead portions disposed on opposite sides of a tire equatorial plane in a tire lateral direction;
• bead cores each provided on a corresponding bead portion of the pair of bead portions;
• and
• a reinforcing layer disposed extending between an inner side and an outer side in a tire lateral direction of the bead cores through an inner side of the bead cores in a tire radial direction,
• the pneumatic tire being mounted on a specified rim with a 5° taper,
• the bead core being formed in a hexagonal shape in a tire meridian cross-section and a bead core bottom corresponding to an inner circumferential surface of the bead core being inclined with respect to a tire rotation axis within a range of 0° or larger and 5° or smaller in a direction in which the bead core bottom extends outward in a tire radial direction as the bead core bottom extends from an inner side toward an outer side in the tire lateral direction,
• in the bead portion, at least a part of a bead base portion corresponding to the inner circumferential surface of the bead portion which part is located inward of the bead core bottom in the tire radial direction being inclined with respect to the tire rotation axis within a range of 8° or larger and 12° or smaller in a direction in which the part extends outward in the tire radial direction as the part extends from the inner side toward the outer side in the tire lateral direction, and
• assuming that a bead width BW is a distance between a tire inner surface and a tire outer surface on a straight line extending through a bead core center in the tire meridian cross-section and parallel to the bead base portion, the bead core has a maximum width CW within a range of (BW×0.54)≤CW≤(BW×0.58) in the tire meridian cross-section.
