  "textContent": "A pneumatic tire comprises a carcass composed of at least one carcass ply made of carcass cords arranged at a cord count E. Each of the carcass cords is composed of two strands final-twisted together. Each of the two strand is made of polyethylene terephthalate fibers first-twisted together. The polyethylene terephthalate fibers of the two strands has a linear density D of not more than 2200 dtex. The linear density D in dtex, the cord count E per 5cm width of the carcass ply, a breaking strength S(N) of the carcass cord, and a Gurley stiffness B (mN) of the carcass cord satisfy conditional equations: E ‰¤ (-30.6 Ln D + 307); B ‰¥ 357/E; and s ‰¥ 4161/E.",
