Document Type and Number:
Japanese Patent JPS6226102
Kind Code:
A
Abstract:
PURPOSE:To aim at the lowering of running noises and the improvement of universality in structure, by specifying the number of inside carcass plies, and also specifying each setup position of organic fiber cord reinforced plies, in case of a tire bearing the above caption, which is provided with plural carcass plies. CONSTITUTION:The number of inside carcass plies 23b is set to half that of carcass plies 23, while organic fiber cords, for example, plural reinforced plies 32a and 32b consisting of 66 nylon is situated at both sides of a crown part center L between a first carcass ply 23b1 and a second carcass ply 23b2 constituting these inside carcass plies 23b, and a central end 33b of these reinforced plies 32a and 32b is situated more outward than an intermediate point 36 between the crown center L and a crown shoulder 10, respectively. In addition, an outer end 33a is set up in having it situated nearer to the side of the shoulder 10 than an intermediate point 37 between the shoulder 10 and a carcass section maximum width position 37.
