Abstract

PURPOSE: To obtain excellent characteristics on operational stability, and so on in such a way that carcass ply cord is arranged with angles of 75°W90° while breaker layer cord is arranged with angles of 30°W60° to the equatorial face on the tire, in a low pressure tire to be used under relatively low load for the purpose of leisure, agricultural vehicles, etc.
CONSTITUTION: A low pressure tire is constructed by one sheet of carcass ply 3 whose both ends 3a are folded back and fixed on left and right bead wires 2, and by a breaker layer 4 which is arranged on the upper side of its crown part. Angle α which is made by fiber cord 3a of the carcass ply 3 is within the range of 75°W90° toward the equatorial face C of the tire while angle β which is made by fiber cord 4a of the breaker layer 4 is within 30°W60°. If they are within these ranges, synthetic characteristics attributable to operational stability, comfortable feeling on rolling wheels, resistance to turning, etc. are exceedingly unrivaled. For further reference, if the carcass ply comprises more than one sheet, the comfortable feeling on rolling wheels is remarkably lowered. Besides, the width of the breaker layer can be selected within the range of 20W130% of the tread width.
