  • Patent number: 10821785
    Abstract: In a pneumatic tire 2 according to the present invention, in the vicinity of a bead 10 portion, a main portion 42 of a carcass ply 40 is passed through the vicinity of a neutral surface. A tensile force and a compressive force applied to the main portion 42 are small. In the tire 2, occurrence of pinch cut is suppressed. In addition, this structure alleviates a force applied to the main portion 42 even during run-flat running. In the tire 2, damage is less likely to occur even during run-flat running for a long period of time. The tire 2 has excellent run-flat durability. Furthermore, in the tire 2, an increase in the vertical stiffness constant or weight thereof is suppressed.
