摘要： A motorcycle tire comprises a carcass and a tread reinforcing layer. The tread reinforcing layer comprises a belt and a band. The band is composed of a jointless band ply having a developed width less than 65% of the developed tread width. The belt is composed of at least one belt ply having a developed width of 65% or more of the developed tread width. At first positions, the intersecting angle between the belt cords and the carcass cords is 20 to 60 degrees. In the tread portion in a tire meridional cross sectional view, a single arc passing through a point on the tread surface at the tire equator and two points on the tread surface at the tread edges has a radius of not more than 0.7 times the maximum tire cross-section width.

摘要： A pneumatic tire includes a reinforcing filler arranged along a bead core. The reinforcing filler includes an inner portion extending in the tire radial direction, outer portion extending in the tire radial direction, and a middle portion extending in the tire axial direction on the radially inner side of the bead core so as to connect the inner portion and the outer portion. The outer portion has an outer end in the tire radial direction located radially inside an outer end in the tire radial direction of the inner portion and located radially outside a center position of a section height of the bead core in the tire radial direction.
