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.
