Description

technical field

[0001] The present invention relates to a tire for two-wheeled vehicles and a method of manufacturing such a tire in which a tape winding method is applied to a shoulder portion of tread rubber. Background technique

[0002] In a tire for a two-wheeled vehicle, the tread portion is formed into a convex arc-like profile with a small radius of curvature in consideration of the characteristics of making a turning motion when the vehicle body is tilted to a large degree. As shown in FIG. 10(A), in order to form the tread portion (a) of such a tire, a profile table (b) (former) having a shape corresponding to the shape of the convex arc profile is used, so that The belt ply (c) and the tread rubber (d) are sequentially stacked along the outer peripheral surface thereof.

[0003] At this time, the tread rubber (d) is formed by: using a wide and flat rubber material (d1) extruded by a rubber extruder; a cylindrical shape; and, while being pressed against the conto...
