Abstract
In a pneumatic tireaccording to the present invention, in the vicinity of a beadportion, a main portionof a carcass plyis passed through the vicinity of a neutral surface. A tensile force and a compressive force applied to the main portionare small. In the tire, occurrence of pinch cut is suppressed. In addition, this structure alleviates a force applied to the main portioneven during run-flat running. In the tire, damage is less likely to occur even during run-flat running for a long period of time. The tirehas excellent run-flat durability. Furthermore, in the tire, an increase in the vertical stiffness constant or weight thereof is suppressed.
