Abstract

A pneumatic tireincludes a pair of beadsand a carcassextending on and between both beads. Each beadincludes a core. The coreincludes: a main bodyincluding a cordextending in a circumferential direction; and a stretchable portionformed from a crosslinked rubber. The stretchable portionis located inward of the main bodyin an axial direction. The stretchable portionhas a size with which at least one cross-section of the cordcan be included therein in a cross-section of the bead. Preferably, in the tire, the main bodyincludes a hard unit and a soft unit. The soft unit is located outward of the hard unit in a radial direction. A hard cord of the hard unit stretches more easily than a soft cord of the soft unit.
