  • Publication number: 20230081835
    Abstract: A tread of a tire can include a cap layer and a base layer. A loss tangent of the cap layer at 30° C. may be not greater than 0.30, and a loss tangent of the base layer at 30° C. may be less than the loss tangent of the cap layer at 30° C. The base layer can be inward of a reference end of the tread in an axial direction A fixing layer can be between the cap layer and a carcass in a radial direction. A first end of the fixing layer can be outward of an end of the base layer in the axial direction, or a position of the first end of the fixing layer can coincide with a position of the end of the base layer in the axial direction. Adhesiveness of the fixing layer can be higher than adhesiveness of the cap layer.
