Pneumatic tire for two-wheeled motor vehicle

A pneumatic motorcycle tire comprising:

• at least a one-layered spiral belt comprising a rubber-coated cord wound in spiral form in the circumferential direction of the tire on the perimeter side of a carcass in a toroidal shape between a pair of bead sections;
• a tread having a curved profile in a cross-section taken along the length of the tread;
• and
• a groove in said tread of which a groove end is located between a central position, between a tire equator and a tread end in the width direction of a tread, and the tread end, on a surface of a tread section in an external side in the radial direction of the tire from the spiral belt, the groove being inclined with respect to the tire equator,
• wherein, in the groove, a groove wall which forms the groove end located between the central position, between the tire equator and the tread end in the width direction of the tread, and the tread end, has a chamfered shape in a cross section in the width direction, and
• wherein the groove has a finite length, the groove end including a corner of the groove, and
• wherein a depth H1 is a distance from the tread surface to a position B at which a planar surface of the chamfered shape is connected to the groove wall in a groove depth direction, and
• wherein a groove depth H2 is deeper than the depth H1,
• wherein, in the groove, the groove wall located between the central position, between the tire equator and the tread end in the width direction of the tread, and the tire equator, has no chamfered shape,
• wherein the groove wall of the groove and an end wall form the corner of the groove end, the groove wall has a chamfered shaped in a cross-section in the width direction of the groove, and the end wall has a chamfered shape in a cross-section in the length direction of the groove.
