摘要： [Problem] It is an object to provide a tire for a motorcycle which realizes a low fuel consumption and is also excellent in a grip performance.[Means for Resolution] A tire (2) includes a tread (4) and a carcass (12) having a radial structure. The tread (4) includes a base layer (21) and a cap layer (22). The cap layer (22) has a center region (23) and a pair of shoulder regions (24) positioned on an outside in an axial direction with respect to the center region (23). A ratio (Wc/Wt) of a width (Wc) of the center region (23) to a width (Wt) of the tread (4) is equal to or higher than 0.15 and is equal to or lower than 0.4. A loss tangent (tan δc) of the center region (23) is smaller than a loss tangent (tan δs) of the shoulder region (24). A loss tangent (tan δb) of the base layer (21) is smaller than the loss tangent (tan δs) of the shoulder region (24). The loss tangent (tan δb) of the base layer (21) is equal to or smaller than 0.15. The loss tangent (tan δb) of the base layer (21) is equal to or smaller than the loss tangent (tan δc) of the center region (23).

摘要： A tire 2 comprises a tread 4, a pair of sidewalls 6 extended almost inward in a radial direction from an end 18 of the tread 4, a pair of bead cores 8 positioned on an inside in the radial direction of the sidewalls 6, and a carcass 10 laid between both of the bead cores 8 along insides of the tread 4 and the sidewalls 6. The carcass 10 includes a carcass ply 20. The carcass ply 20 is turned up around the bead core 8. The sidewall 6 has a lower layer 34 positioned on an outside in an axial direction of the carcass ply 20 and an upper layer 36 positioned on an outside in the radial direction of the lower layer 34. The upper layer 36 has a hardness which is equal to or higher than 50 and is equal to or lower than 70. The lower layer 34 has a hardness which is equal to or higher than 70 and is equal to or lower than 100.

摘要： A motorcycle tire comprises a tread portion having a tread width between tread edges. The tread portion is provided with a crown oblique groove disposed within a center region of the tread portion is defined as having 30% of the tread width. The center region having a radius of curvature of from 0.60 to 0.75 times the tread width in a meridian section of the tire, and the center region has a land ratio in a range of from 0.75 to 0.95. The crown oblique groove extends continuously or discontinuously in the tire circumferential direction, across the tire equator a plurality of times, and the crown oblique groove is inclined at angles of not more than 20 degrees with respect to the tire circumferential direction.
