Abstract:
A tire includes a pair of beads, a carcass, chafers, an insulation, and cushion layers. Each bead includes a core positioned inward of the bead in a radial direction. At an inside of the core in the radial direction, the insulation is laminated on the chafers so as to be located outward of the chafers in the radial direction. Each cushion layer is laminated on the insulation so as to be located outward of the insulation in the radial direction. The insulation and the cushion layer are formed from respective crosslinked rubbers different from each other. A compressive elastic modulus Eα* of the crosslinked rubber of the cushion layer is smaller than a compressive elastic modulus Eβ* of the crosslinked rubber of the insulation.
