Abstract
A motorcycle pneumatic tire, in which the tread includes a central rubber and a side rubber, having a lower modulus than the central rubber, that are sequentially laminated in both tire widthwise side portions, the side rubber extending to a tire width-direction inner side further than a point at ¼ of a tread width on a tire width-direction outer side from a tire equator. A tire ground-contact surface has a tread pattern that includes plural inclined grooves and, when the tread width is equally divided in eight, a region constituting a range of ¼ to ⅜ of the tread width on the tire width-direction outer side from the tire equator has the largest number of inclined grooves included per a single pitch of the tread pattern, and the depth of the inclined grooves is greater than the thickness of the side rubber in at least a part of the region.
