A tire 2 includes a tread 4, a belt 16, and a band 18. The belt 16 includes belt cords 44. The band 18 includes band cords 60. The band 18 is composed of a band strip 58. The band strip 58 is a cord array in which the band cords 60 are arranged. A zone from a first end to a second end of the belt 16 is a control zone. Residual tension of the band cords 60 in the control zone is not less than 15.0 N. The control zone includes a crown zone and a pair of shoulder zones. Residual tension of the band cords 60 in the crown zone is higher than residual tension of the band cords 60 in each shoulder zone. A shape index of a reference ground-contact surface of the tire 2 is not less than 1.00 and not greater than 1.30.
