Abstract
In a pneumatic tire on a rim with 5° taper, a bead core includes a bead core bottom inclined 0° to 5° with respect to a rotation axis in a direction in which the bead core bottom extends outward in a radial direction from an inner side toward an outer side in the lateral direction, a bead portion includes a bead base portion inclined 8° to 12° with respect to the rotation axis in a direction in which the bead base portion extends outward in the radial direction from the inner side toward the outer side in the lateral direction. A bead width BW is a distance between tire inner and outer surfaces on a straight line through a bead core center in the 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).
