Tire frame step portions 18 are formed to a tire frame member 17. The tire frame step portions 18 are formed further toward the tire equatorial plane side than tire axial direction end portions 30A of a tread member 30. Covering layers 24 are formed at the outside of the tire frame member 17 so as to span from bead portions to the tire frame step portions 18.

A polyamide-based thermoplastic elastomer including a hard segment and a soft segment, wherein the hard segment contains polyamide 612 and the soft segment contains a polyamine.

A polyamide-based thermoplastic elastomer including a hard segment and a soft segment, wherein the hard segment contains polyamide 612 and the soft segment contains a polyamine.

A tire includes: a tire frame member formed in a ring shape from a frame resin material, and including a pair of bead sections, a pair of side sections, and a crown section; 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; and 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.

A tire comprises a rubber member formed of a rubber composition comprising a diene-based rubber, and a ring-shaped tire frame formed of a resin material comprising a polyamide-based thermoplastic resin, in which the rubber member is adhered to a resin member including a polyamide-based thermoplastic resin via a layer formed of a composition including a resorcinol-formalin-latex-based adhesive.

A tire, including a circular tire frame formed of a resin material, the resin material including a resin composition in which at least one thermoplastic resin selected from the group consisting of a polyamide-based thermoplastic resin, a polyester-based thermoplastic resin, and a polyolefin-based thermoplastic resin, and at least one elastomer selected from the group consisting of a diene-based rubber, a vinyl acetate copolymer, a polyurethane, an ethylene propylene rubber, and any modified product thereof have been dynamically crosslinked.
