(57) [Abstract] [Purpose] To provide a pneumatic tire and a manufacturing method thereof, in which the tire weight is reduced by thinning the inner liner layer, and the performance of retaining the air pressure in the tire is improved. . [Structure] A nylon film layer is adhered to the inside of a green tire made of unvulcanized rubber, and then the green tire is molded and vulcanized to form an inner liner layer made of the nylon film layer. As a nylon film layer, It is recommended to use a nylon 6 type unstretched film, especially a nylon 6 type unstretched film surface dipped in a resorcinol formaldehyde latex solution, a nylon 6 type unstretched film surface treated with a silane coupling agent, or nylon 6 It is possible to use a type unstretched film whose surface is firstly treated by corona discharge and then secondarily treated with a silane coupling agent. |
