Abstract
A pneumatic tire includes a tread portion including main grooves and land portions. In a cross-sectional view of the tire, one of the land portions includes a first edge, a second edge, a ground contact surface extending between the first edge and the second edge and having an arc-shaped profile protruding radially outwardly, and conductive portion made of conductive rubber. The conductive portion extends from a radially inner end to a radially outer end exposed at the ground contact surface with an inclination toward the first edge. The inner end is connected to a tire internal structural member to be electrically connected to a rim when the tire is mounted on the rim. On the ground contact surface, a central position of the outer end is located on a central position of the land portion in a tire axial direction, or on a side of the first edge.
