Provided is a pneumatic tire including: a pair of bead portions 11; a pair of side wall portions 12; and a tread portion 13, and including a carcass layer 2 composed of at least one carcass ply extending toroidally between bead cores 1 embedded in the pair of bead portions respectively as a skeleton. A reinforcing layer 4 using a reinforcing material composed of a core/sheath-type composite fiber (C) in which a core portion is made of a high melting point polyolefin-based resin (A) having a melting point of 150°C or higher and a sheath portion is made of a low melting point polyolefin-based resin (B) having a melting point of 80°C or higher and lower than 150°C is provided on at least the outside of the bead core in the tire radial direction.",
