Title:
RADIAL TIRE
Document Type and Number:
WIPO Patent Application WO/1984/001748
Kind Code:
A1
Abstract:
An improvement to the bead structure of a radial tire consists of: a reinforcing layer of high-elasticity cords provided outside an upward-curled edge portion of a carcass; an inner protective layer positioned between the reinforcing layer and the upward-curled edge portion; and an outer protective layer positioned so as to be adjacent to the outer surface of the reinforcing layer. These protective layers have a height extending beyond the upper end of the reinforcing layer. The inner protective layer has cords in substantially the same direction as the cords of the reinforcing layer, while cords of the outer protective layer are arranged in a direction that crosses the cords of the reinforcing layer.
