  "textContent": "Provided is a pneumatic tire used with a specified rotation direction, including a tread, a pair of sidewalls extending continuously from the tread inward in a tire radial direction, a pair of beads continuous with the sidewalls inward in the tire radial direction, and at least one ridge on a buttress surface. The buttress surface extends from a tread edge of a tread surface formed on the tread to the sidewall. The ridge extends from a sidewall side of the buttress surface towards the tread edge and terminates before reaching the tread edge. The ridge includes a steeply inclined surface, having a high gradient with respect to the buttress surface, inclined forwards in the rotation direction, and a moderately inclined surface, having a more moderate gradient than the steeply inclined surface, inclined backwards in the rotation direction.",
