Also provided is a production method for said pneumatic tire. The pneumatic tire is provided with an asymmetrical tread pattern in which the negative ratio of the pair of tread halves between the equatorial plane of the tire on the tread section and both outer ends of the tread section in the tire width direction is different for both tread halves, and is characterized in that short fibers are fixed on at least a portion of the inner peripheral tire surface on the tread section and the area ratio of fixed short fibers on the tread half with the higher negative ratio is lower than that of the other tread half.
