Pneumatic tire with specified carcass folded section and notched portion
Abstract:
A pneumatic tire includes a carcass having a first portion in which a distance between ply cords of a carcass body section and a carcass folded section gradually decreases from a position of a bead core toward outside in a radial direction of the tire, a second portion in which the distance between the ply cords gradually increases from the first portion toward outside in the radial direction of the tire, and a third portion in which the distance between the ply cords gradually decreases from the second portion toward outside in the radial direction of the tire. A notched portion is provided on a widthwise outer skin rubber of the carcass folded section of the second portion by notching the widthwise outer skin rubber inwardly in the width direction of the tire.
