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 motorcycle tire comprises a tread reinforcement including a jointless band ply. The jointless band ply has a developed width Wa of not more than 65% of the developed tread width TWe. The tread portion has a tread profile comprising a crown arc portion having a radius R1 of curvature and a pair of shoulder arc portions having a radius R2 of curvature. The radius R1 is smaller than the radius R2 and smaller than 50% of the maximum tire cross-section width Wt. In a normal state of the tire, the axial ends of the crown arc portion are respectively positioned axially inward of the outer edges of the jointless band ply.

摘要： A tire includes a tread portion having a ground contacting surface and a first groove. A tread rubber forming the tread portion includes a first rubber layer and a second rubber layer. The second rubber layer has a complex elastic modulus smaller than a complex elastic modulus of the first rubber layer. The first groove includes a first groove edge, a groove bottom surface, and a first groove wall. In a lateral cross section of the first groove, the first groove wall includes a first wide top portion arranged between the first groove edge and the groove bottom surface and located outside the first groove edge in a groove width direction of the first groove. The first wide top portion is positioned in the second rubber layer.

摘要： A tyre includes a crown main groove formed by unit patterns. Each of the unit patterns includes a first inclined element, a second inclined element, a first bent element, and a second bent element. The first inclined element extends obliquely. The second inclined element extends obliquely in a direction opposite to the first inclined element. The first bent element extends so as to connect between the first inclined element and the second inclined element. The second bent element is connected with the second inclined element. The first bent element is bent so as to be convex toward the first tread edge without having a component extending in parallel with the tyre circumferential direction. The second bent element is bent so as to be convex toward the second tread edge without having the component extending in parallel with the tyre circumferential direction.

摘要： A tire comprises a tread portion comprising a shoulder land region provided with shoulder lateral grooves and circumferential sipes connecting between the shoulder lateral grooves. The shoulder lateral grooves are each provided with a chamfer. The circumferential sipes are each spaced apart from an axially inner end of the shoulder land region by an axial distance of from 30% to 100% of an axial width of the shoulder land region. The depths of the circumferential sipes are equal to or greater than the groove depths of the shoulder lateral grooves.
