Abstract: Disclosed are a pneumatic tire that includes a tread having a pattern asymmetrical about the tire equatorial plane, and that is easy to produce and may surely reduce cavity resonance without lowering repair efficiency, and a method of producing the same. 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 lower short-fiber fixation area ratio than that of the other tread half.

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 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.
