Abstract

PURPOSE: To decrease transverse displacement of a tire when large cornering force is applied thereon, by a method wherein two kinks of reinforcement ply, of which values of initial modulus are different from each other, and combined, in a tire of which aspect ratio is within the specified range.
CONSTITUTION: In an extremely flat tire of which aspect ratio is within the range of 0.02W0.75, for instance, a ply 2 is double by consisting of fiber cord, of which initial mudulus is in the range of 15'70grams/denier. The reinforcement ply cord 6 to be combined with the above-mentioned ply is that of which initial modulus is above 100grams/denier, and is laid on the ply 2 at an angle in the range of 20W60 degrees to the equatorial plane, and in the number of cord in the range of 4W 12pieces/cm, consisting of a reinforcement ply. With such an arrangement, the transverse force to a tire, even to the part of a side wall, having reinforcement ply on it, caused by the shock due to the unevenness of the surface of road and so forth during cornering can be absorbed by a casing part 7, where a reinforcement ply is not equipped.
