Abstract: A pneumatic tire with short fibers fixed to the inner surface of the tire with improved peel resistance, and a method of producing such a pneumatic tire. The pneumatic tire has a carcass toroidally extending from a tread portion along a pair of sidewall portions to a pair of bead portions, and bead fillers provided radially outwardly of bead cores embedded in the bead portions, including flocking areas in which many short fibers are fixed to at least part of an inner surface of the pneumatic tire with an adhesive. The flocking areas are positioned such that their tire radial direction inner ends are positioned inwardly in the tire radial direction as compared to the tire radial direction outer ends of the bead fillers and are spaced a given distance outward in the tire radial direction apart from bead toes.

Abstract: The belt layer (50) of the pneumatic tire (10) includes one inclined belt (50 A) having an inclined cord inclined with respect to the tire width direction, and a circumferential belt (50 B) disposed outside the tire radial direction of the inclined belt (50 A) and having a circumferential cord (52) wound along the tire circumferential direction. The inclined cord and the circumferential cord are formed of a predetermined organic fiber. The tread thickness (T1) of the rubber forming the tread portion (20) along the tire radial direction at a tire equatorial line (CL) is 5 mm or less.

Abstract: At a pneumatic tire (11), in a pneumatic tire in which a reinforcing layer (11) is structured from at least one reinforcing ply (53) in which are embedded plural reinforcing cords (54) that are formed from steel and are inclined with respect to a tire equator S, an inclination angle A of the reinforcing cords (54) with respect to the tire equator S is within a range of 40 to 90°, and a compressive rigidity F per 50 mm width of a reinforcing layer (52) in a direction parallel to the reinforcing cords (54) is within a range of 1000 to 2400 N.
