Abstract
A tread of a tire includes a plurality of blocks including a center block located on an equator plane and a side block located outward of the center block in an axial direction. Each of the plurality of blocks includes a land surface that forms a part of a tread surface. In the tread surface, a total area of the land surfaces is smaller than a total area of a portion other than the land surfaces. A complex elastic modulus at a maximum strain amplitude of 1% and a temperature of 70° C. of each block is not less than 10.0 MPa. A 300% modulus at a temperature of 75° C. of each block is not greater than 6.0 MPa.
