In a standardized load-applied state, groove walls 6 of the shoulder circumferential groove 3 are not in contact with each other, and at least parts of groove walls 7 of the crown circumferential groove 4 are in contact with each other. The crown circumferential groove 4 has a widened portion 10 on an inner side in a tire radial direction with respect to a tread ground-contact surface 2s. A groove width W2 of the widened portion 10 is larger than a groove width W1 at the tread ground-contact surface 2s of the crown circumferential groove 4. An outer end 25 on a first tread end T1 side of a jointless band ply 20A is located on an outer side in a tire axial direction with respect to an outer end 3e of the shoulder circumferential groove 3.",
