PROBLEM TO BE SOLVED: To provide a tire formed of a thermoplastic polymer material, and excellent in durability and production ability.SOLUTION: The tire is formed of a thermoplastic resin material, has an annular tire skeleton body, in which the tire skeleton body is formed of only one layer formed of a thermoplastic resin material. The tire skeleton body comprises a reinforcement cord layer including a coating reinforcement cord member wound around an outer peripheral part of the tire skeleton body in a peripheral direction, the thermoplastic resin material includes a predetermined polyester-based thermoplastic elastomer by a predetermined percentage content, at least part of the outer peripheral surface of the tire skeleton body having the reinforcement cord layer has an irregularity in which arithmetic average roughness Ra equal to or more than 0.05 mm. The coating reinforcement cord material is formed of a metal cord member and a coating resin material which is independent from the thermoplastic resin material forming the tire skeleton body, and comprises a coating layer for coating the metal cord member, the coating resin material is a resin material being a same material to the thermoplastic resin material forming the tire skeleton body and includes no vulcanization rubber.SELECTED DRAWING: None |
