PNEUMATIC TIRE

摘要

A pneumatic tire includes beads, a carcass and a belt. The carcass ply is turned up around the beads from axially inner sides toward axially outer sides respectively such that the carcass ply includes a main portion bridging the beads and turn-up portions positioned on the axially outer sides of the beads and extending in a radially outward direction, respectively, each of the beads includes a core including wires such that the wires extend in a circumferential direction, the core has two or more strands and turns which are three times a number of the strands or more, the wires have a radially outer edge positioned on a radially inner side of a radially outer edge of a flange of a normal rim when the pneumatic tire is mounted on the normal rim, and each of the turn-up portions has an outer-edge part overlapping an edge portion of the belt.
