Tire with chafer structure for improved bead durability

摘要

The present invention provides a tire having improved bead endurance in which cords (110) of a steel chafer (100) are waved and the advancing direction of the waves of the steel chafer (100) is perpendicular to the advancing direction of carcass cords (210), thereby minimizing cracks at an edge (220) of the carcass (200). The tire having a chafer structure for enhancing bead endurance includes: a carcass (200) having carcass cords (210); and a steel chafer (100) covering the carcass and having a plurality of waved chafer cords (110).
