  "textContent": "In a pneumatic tire including a side reinforcing layer, the maximum width Wof a bead core and the widths W W of the bead core at innermost and outermost sides in the radial direction, respectively, satisfy WW and W×W W is toward the inside of the center of the bead core in the radial direction. A carcass is folded and curved along the bead core, and a folded back portion of the carcass extends toward the sidewalls while contacting a body of the carcass. A rubber occupancy ratio in a region formed by the body and the folded back portion of the carcass is 0.1% to 15%. The cross-sectional area S of a filler toward the outside of the carcass in the lateral direction, the hardness H of the filler, the cross-sectional area Sof a side reinforcing layer and the hardness H of the side reinforcing layer satisfy 0.15≤(SH)/(SH)≤0.60.",
