A tire 2 includes a pair of beads 6, a carcass 8, chafers 16, an insulation 12, and cushion layers 14. Each bead 6 includes a core 18 positioned inward of the bead in a radial direction. At an inside of the core 18 in the radial direction, the insulation 12 is laminated on the chafers 16 so as to be located outward of the chafers 16 in the radial direction. Each cushion layer 14 is laminated on the insulation 12 so as to be located outward of the insulation 12 in the radial direction. The insulation 12 and the cushion layer 14 are formed from respective crosslinked rubbers different from each other. A compressive elastic modulus E±* of the crosslinked rubber of the cushion layer 14 is smaller than a compressive elastic modulus E²* of the crosslinked rubber of the insulation 12. |
