Abstract
A pneumatic tires includes a tread, a pair of sidewalls, and a pair of bead portions that are arranged at intervals wider than a rim width of a corresponding regular rim in a non-rim-assembled state. Each of the pair of the bead portions includes a bead base at an inner diameter side end, a bead heel, and a bead back surface extending from an outer diameter side end of the bead heel, to the outer diameter side. In the non-rim-assembled state, the bead back surface is formed with a recess that is recessed inward in the width direction. In a rim-assembled state, the bead back surface is in close contact with substantially the entire surface of a radial portion of a rim flange of a regular rim.
