Abstract
Official abstract text for this publication.
[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 ).
