[0002] A tire (1) includes a belt layer (7) in a tread portion (2). The belt layer (7) includes at least one belt ply (7A, 7B). The belt ply (7A, 7B) includes belt cords (9) made of steel single wires (9A) having a flat cross-sectional shape and a topping rubber (10) covering the belt cords (9). The topping rubber (10) has a complex elastic modulus ES at 70 degrees Celsius in the range of from 8.0 to 20.0 MPa and a loss tangent tanδ at 70 degrees Celsius in the range of from 0.04 to 0.14.",
