Pneumatic tire

Abstract

Provided is a pneumatic tire in which, by improving adhesion between a rubber and fibers for a reinforcing layer that is arranged in such a manner to extend from a tire radial-direction inner side of a belt layer in an end region of a tread portion toward an inner side of a tire radial direction along a carcass ply, not only the durability is further improved as compared to conventional tires but also the rolling resistance is reduced. The pneumatic tire includes: at least one carcass ply (2); and at least one belt layer (3) arranged on a tire radial-direction outer side of the carcass ply (2) in a crown portion, in which pneumatic tire a reinforcing layer (4) extending from the tire radial-direction inner side of the belt layer in the end region of the tread portion toward the inner side of the tire radial direction along the carcass ply is arranged, and core-sheath type composite fibers (C), whose core portion is composed of a high-melting-point resin (A) having a melting point of 150° C. or higher and sheath portion is composed of a resin material (B) that contains an olefin-based polymer (D) having a melting point of not higher than a tire vulcanization temperature, are embedded in the reinforcing layer.
