Abstract: A motorcycle tire is provided that is capable of remarkably improving a traction characteristic and an anti-sideslip characteristic for cornering without deteriorating the mud expulsion characteristic especially on a dirt road. In embodiments, a motorcycle tire has a plurality of main blocks scattered on a tread. Sub blocks are provided between the main blocks. The sub blocks are made of rubber and have a block height H2 lower than that the height H1 of the main blocks. A part of the rubber constituting a top portion of the sub block is removed to reduce the area of a upper face of the sub block.

Abstract: Disclosed is a pneumatic tire for motorcycle wherein edge effect can be achieved without changing the design of block pattern, and stability of steering such as grip, feeling of grounding, or controllability of slip is enhanced. When a block having a recess in which a protrusion is formed on the bottom is provided in a tread, edge component increases correspondingly as compared with a block provided only with a recess (having no protrusion), and thereby traction can be enhanced. Since it is not required to increase the hardness of rubber of the read nor to enlarge the block size, feeling of grounding is ensured and controllability of slip can be ensured in a muddy place or on a soft road surface.

Abstract: A center block and a second block that satisfy h1/H=0.05 to 0.4 and w1/W=0.05 to 0.4 are formed on a tread, where H is the block height, h1 is the drop in height of a chamfered part, w1 is the breadth of the chamfered part and W is the length of the block tread in a circumferential direction. When traveling on hard pavement, the chamfered part of the block contacts the hard pavement first and, compared to a case in which an edge that does not have a chamfered part contacts a hard pavement, the ground-contact surface area can be increased and steering stability on hard pavement can be improved. Further, in rough terrain, resistance received from a road surface at the time of ground contact is reduced, travel resistance is suppressed and steering stability is improved.

Abstract: A tire (1) for a motorcycle has: a groove portion (10) formed at a tread; and a block-shaped land portion (100) protrusive from the groove portion (10) toward an outside in a tire radial direction (TD). The land portion (100) has a plate-shaped small piece portion (107). Since an area with which the running wind comes into contact increases due to the small piece portion (107), the periphery of the groove portion (10) or the land portion (100) can be effectively thermally radiated. Thus, a temperature of the land portion (100) can be reduced, and even if the automatic motorcycle runs on the hard road surface over a predetermined period of time or more, it is possible to effectively restrain the lowering of required performance such as gripping force, feeling of grounding, and steering stability, which is exerted by the lowering of the rigidity of the land portion.
