PNEUMATIC TIRE FOR MOTORCYCLE AND METHOD OF MANUFACTURING THE SAME

摘要

A pneumatic tire for a motorcycle increased in durability by a tread part formed of a rubber strip laminated body and a method of manufacturing the tire. The pneumatic tire (1) comprises the tread part (5) formed of the rubber strip laminated body (8) formed by spirally winding rubber strips (11) continuously in the circumferential direction of the tire. The outermost layer (10a) of the rubber strip laminated body (8) forming a tread part tread (9) is so formed that virtual extension planes (p) formed by extending boundary surfaces between the rubber strips forming the outermost layer from the tread part tread (9) to the outside of the tire can be positioned on the tread end sides of normal lines (n) formed vertically to the tread part tread (9). The tire (1) thus obtained is manufactured by winding the rubber strips (11) in order starting at a tread end to a tire equator plane (CL) when the outermost layer of the rubber strips is formed to form the tread part tread.
