摘要： Provided is a pneumatic tire by which productivity and handling stability are improved. A pneumatic tire comprises: a carcass that spans from a tread section, through a side wall section, and to a bead core of a bead section; a bead apex rubber that has a roughly triangular cross-sectional shape and extends in a tapered shape from the bead core toward the tire radial outer side; and a bead reinforcement material that is wound in a spiral shape around the bead apex rubber or a composite of the bead apex rubber and the bead core.
