A tire comprising: a tire frame member formed in a ring shape from a frame resin material, and including a pair of bead sections disposed separated from each other along the tire width direction, a pair of side sections that extend from the pair of bead sections toward the tire radial direction outside, and a crown section that connects together the pair of side sections; and a ring shaped bead core that is embedded in and joined to each of the bead sections, and that is formed by a single strand, or plurality of strands, of bead cord extending in the tire circumferential direction, and covered with, and joined to, a covering resin material; characterized in that the tire comprises: an extension portion that extends from each of the bead cores in a direction that intersects with the tire circumferential direction when viewed from a tire side face, and that is joined to the tire frame member, wherein the extension portion extends from the bead core toward the tire radial direction outside; wherein a plurality of the extension portions are formed at intervals around the tire circumferential direction; wherein the covering resin material exhibits thermo-plasticity; wherein each of the extension portions is formed with the same material as the covering resin material; and wherein each of the extension portions is formed by extending a portion of the covering resin material configuring the bead core toward the tire radial direction outside. a tire frame member formed in a ring shape from a frame resin material, and including a pair of bead sections disposed separated from each other along the tire width direction, a pair of side sections that extend from the pair of bead sections toward the tire radial direction outside, and a crown section that connects together the pair of side sections; and a ring shaped bead core that is embedded in and joined to each of the bead sections, and that is formed by a single strand, or plurality of strands, of bead cord extending in the tire circumferential direction, and covered with, and joined to, a covering resin material; characterized in that the tire comprises: an extension portion that extends from each of the bead cores in a direction that intersects with the tire circumferential direction when viewed from a tire side face, and that is joined to the tire frame member, wherein the extension portion extends from the bead core toward the tire radial direction outside; wherein a plurality of the extension portions are formed at intervals around the tire circumferential direction; wherein the covering resin material exhibits thermo-plasticity; wherein each of the extension portions is formed with the same material as the covering resin material; and wherein each of the extension portions is formed by extending a portion of the covering resin material configuring the bead core toward the tire radial direction outside. an extension portion that extends from each of the bead cores in a direction that intersects with the tire circumferential direction when viewed from a tire side face, and that is joined to the tire frame member, wherein the extension portion extends from the bead core toward the tire radial direction outside; wherein a plurality of the extension portions are formed at intervals around the tire circumferential direction; wherein the covering resin material exhibits thermo-plasticity; wherein each of the extension portions is formed with the same material as the covering resin material; and wherein each of the extension portions is formed by extending a portion of the covering resin material configuring the bead core toward the tire radial direction outside.
