摘要： Provided is a pneumatic tire for a motorcycle which does not produce a failure such as early wear or uneven wear and which has improved grip while turning. The pneumatic tire for a motorcycle is a pneumatic tire for a motorcycle including a ring-shaped tread portion. The tire has, inside in the tire radial direction of the crown portion, at least one spiral belt layer having a width narrower than the width of the tread portion; at the shoulder portion of the tread portion, an inner layer rubber having a smaller modulus at 300% elongation at room temperature than that of a surface layer rubber is arranged; the inner layer rubber extends to a buttress portion; and the range of the ratio of the moduli between the inner layer rubber and the surface layer rubber is from 0.3 to 0.9.

摘要： A tire having aggressive tread features with improvements in uniformity that can also improve endurance is provided along with a method and apparatus for manufacturing such a tire. The tire and its manner of manufacture can achieve a reduction or elimination of certain non-uniformities that can occur during the molding of large tread blocks. This can improve temperature performance to provide increased tire endurance. The present invention further relates to a tire made using such a method and that may have layers of different material properties for different tire performances. In one embodiment, a layering technique that uses at least one layer extending across the full axial width of the tread and having scalloped or notched lateral or axial edges is provided. In yet another embodiment, tread blocks are built upon the scalloped layer(s) to provide more material where it is needed most to create tread features.
