<p>Provided is a pneumatic tire manufacturing method that enables a reinforcing effect to be more effectively obtained in terms of cost and weight. Also provided is a pneumatic tire that achieves a desired reinforcing effect while satisfying basic performance as a tire. The method for manufacturing a pneumatic tire involves disposing reinforcement members, which are formed by placing layers of reinforcing fiber pieces comprising a plurality of reinforcing fiber pieces, which are obtained by cutting reinforcing fibers at a predetermined length, between a pair of strip-shaped unvulcanized rubber sheets, on the sidewalls in the circumferential direction of the tire. When manufacturing a raw tire, in a tire molding step conducted prior to an extension step, the reinforcing members are attached to the sidewalls in such a manner that the density of the reinforcing fibers has a density gradient that is higher at the end on the tread section side than on the end on the bead section side.</p> |
