Problems solved by technology

[0006] However, in pneumatic tires, especially high-speed tires represented by high-performance tires, when the rubber strip is laminated from the outside to the inside of the tire, there is a problem that a large side is input during high-speed driving. When the force is resisted, the overlapping winding part of the narrow belt member is raised due to the lateral resistance, that is, the crack generated around the interface is extended and developed, thereby deteriorating the wear resistance
However, the invention described in Patent Document 1 does not provide a solution to this problem

Embodiment

[0057] Table 1 summarizes the embodiment products of the present invention compared with conventional tires.

[0058] That is, two tires are compared: the tire specification is set to 285 / 30R18 (in Japan, it is the tire specification stipulated by the Japan Automobile Tire Association "JATMA Year Book", in the United States, it is specified by "The Tire and Rim Association Inc. Year Book" stipulated tire specifications, in Europe, the tire specifications stipulated by "The European Tire and Rim Technical Organization's Standards Manual"); for its carcass layer, the cord type is ply twisted cord, angle (relative to the circumference The direction) is 0°, the number of layers is 2 layers, as a steel wire bias belt layer, the cord type is ply twisted cord, the angle (relative to the circumferential direction) is 55°, and the helix is ​​polyamide CAP; for the tire On both sides, the ribbon helically wound plies are common; the two tires differ only in the direction of the plies. ...

Abstract

A pneumatic tire capable of maintaining its durability at high speeds to improve wear resistance by minimizing the affection of a cornering force thereon, an arrangement structure of the tire, and a method of manufacturing the tire. A tread is formed by spirally winding a narrow ribbon-shaped rubber member (1) having a gauge of 0.5 to 2 mm and a width of 5 to 15 mm continuously and repeatedly in the lateral direction of the tire (T) by partial overlapped winding. The advancing direction of the spiral winding is aligned with the direction of the tire facing from the inside to the outside when mounted on a vehicle so that the cornering force provided to the pneumatic tire (T) when the vehicle having the tire is running touches the exposed surface of the laminated ribbon-like rubber member (1).

Description

technical field [0001] The present invention relates to a pneumatic tire, and in particular, to a pneumatic tire having improved wear while maintaining the high-speed durability of a high-performance radial tire, an arrangement structure of the tire, and a manufacturing method thereof. Background technique [0002] In recent years, affected by the trend of unmanned molding of tire manufacturing methods, factory downsizing, or the expansion of the effectiveness of dividing the tread in the width direction, compared with the conventional extrusion molding method, a new method of continuous and repeated part molding has been gradually developed. A technique of overlapping rectangular members to form a tread. [0003] In such a molding method, when the belt-shaped object is gradually wound and formed into a spiral shape, it is difficult to make the gap between the belt-shaped object The winding is carried out with no gap and precise control, and the productivity is also hindere...
