摘要： This invention provides a pneumatic tire provided with a carcass (4) comprised of one or more carcass plies formed by covering plural reinforcing cords arranged in parallel with a coating rubber and a pair of side reinforcing rubber layers (5) each having a crescent shape in section and disposed at an inside of the carcass, wherein ride comfort during usual running and durability during run-flat running are improved by applying a cord including a polyketone fiber and satisfying conditions of equation (I): σ≧−0.01×E+1.2 and equation (II): σ≧0.02 [wherein σ is a heat shrinkage stress (cN/dtex) at 177° C. and E is an elastic modulus (cN/dtex) at 25° C. under a load of 49 N] to the reinforcing cord and a rubber composition having a loss tangent (tan δ) at 25° C. and 1% strain of less than 0.12 and a viscosity (G′) at 130° C. during unvulcanization of not less than 50 MPa to the coating rubber.
摘要翻译：本发明提供一种充气轮胎，其具备胎体（4），所述胎体（4）由一个或多个胎体帘布层组成，所述胎体帘布层通过覆盖与涂覆橡胶平行布置的多个加强帘线和一对具有月牙形的侧面增强橡胶层（5）并且设置在胎体的内部，其中通常运行期间的乘坐舒适性和跑平运行期间的耐久性通过施加包含聚酮纤维的绳索并满足等式（I）的条件而得到改善：σ= -0.01×E + 1.2 和式（II）：σ= 0.02 [其中σ为177℃时的热收缩应力（cN / dtex），E为在25℃负荷下为25N时的弹性模量（cN / dtex） ]和在25℃下具有损耗角正切（tanδ）和小于0.12的1％应变和130℃下的粘度（G'）的橡胶组合物，在不硫化时不小于50MPa 涂布橡胶。
