Abstract: A pneumatic tire in which a cavity resonance sound is reduced while punctures are easily repaired with a puncture sealant. The pneumatic tire has a fibrous region where short fibers are bonded onto an inner surface of the tire. A circumferential fiberless region where short fibers are not bonded onto the inner surface of the tire extends circumferentially between both ends of a tread ground contact area.

Abstract: Disclosed is a pneumatic tire that includes a tread having a pattern asymmetrical about the tire equatorial plane, and that may reduce cavity resonance and has good steering stability. A pneumatic tire includes a tread portion having a pair of tread halves, the tread halves extending between the tire equatorial plane and respective outer ends in the tire width direction of the tread portion, respectively, and having different negative ratios. The tread portion has short fibers fixed to at least a portion of a tire inner peripheral surface of the tread portion, and one of the tread halves with a higher negative ratio has a higher short-fiber fixation area ratio than that of the other tread half.

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.
