Abstract: A pneumatic tire includes: a belt layer in which a belt cord is arranged; and a belt reinforcing layer in which an organic fiber cord is arranged, the belt reinforcing layer is formed by coating the organic fiber cord with rubber, and a ratio (Sr/Sc) of a rubber cross-sectional area (Sr) to a cord cross-sectional area (Sc) is 1.0 to 1.5, and a value obtained by dividing, by 1000, a sum of a product (A) of a load LASE5% (N) at 5% elongation of the organic fiber cord, a cord count (per 25 mm), and the number of belt reinforcing layers, and a product (B) of a load (N) at 0.5% elongation of the belt cord, cos ? in which a belt angle is defined as ?, a cord count (per inch), and the number of belt layers is 8.7 or more.

Abstract: A pneumatic tire containing a polyester (e.g., polyethylene terephthalate or polyethylene naphthalate) derived from a non-fossil raw material. In a preferred embodiment, a polyester (e.g., polyethylene terephthalate or polyethylene naphthalate) in which a linear or cyclic moiety is produced using a raw material derived from a non-fossil raw material is used in the pneumatic tire. A pneumatic tire in which polyethylene terephthalate or polyethylene naphthalate produced using a raw material derived from a non-fossil raw material is used as a carcass material or a belt reinforcing material.
