To provide a tire inner liner formed by using a cylindrical film (10) including a thermoplastic material and obtained by inflation molding, in which a ratio of breaking strength in a tire width direction (14) to breaking strength in a tire circumferential direction (18) of the cylindrical film (10) is from 1.35 to 1.80. A pneumatic tire (1) is obtained by extruding and molding the cylindrical film (10) in which a ratio of breaking strength in an extrusion direction (12) to breaking strength in a direction perpendicular to the extrusion direction (16) is from 1.35 to 1.80 by inflation molding using a thermoplastic material, forming a green tire by placing the obtained cylindrical film (10) on a forming drum so that the extrusion direction (12) becomes the tire width direction (14), and vulcanizing and molding the green tire.
