A tire comprising: a tread portion having a first tread end (T1), wherein the tread portion has a shoulder circumferential groove adjacent to the first tread end (T1), and a crown circumferential groove provided between the shoulder circumferential groove and a tire equator (C), each of the shoulder circumferential groove and the crown circumferential groove includes a pair of groove walls , in a standardized load-applied state where the tire is fitted on a standardized rim at a standardized internal pressure, a standardized load is applied to the tire , and the tire is brought into contact with a flat surface at a camber angle of 0°, the pair of groove walls of the shoulder circumferential groove are not in contact with each other, and at least parts of the pair of groove walls of the crown circumferential groove are in contact with each other, the crown circumferential groove has a widened portion on an inner side in a tire radial direction with respect to a tread ground-contact surface , a groove width (W2) of the widened portion is larger than a groove width (W1) at the tread ground-contact surface of the crown circumferential groove , a band layer including a jointless band ply in which a band cord is helically wound at an angle of 5 degrees or less with respect to a tire circumferential direction is provided inside the tread portion , and the jointless band ply is placed so as to cover the tire equator (C), characterized in that an outer end in a tire axial direction on the first tread end (T1) side of the jointless band ply is located on an outer side in the tire axial direction with respect to an outer end in the tire axial direction of the shoulder circumferential groove . a tread portion having a first tread end (T1), wherein the tread portion has a shoulder circumferential groove adjacent to the first tread end (T1), and a crown circumferential groove provided between the shoulder circumferential groove and a tire equator (C), each of the shoulder circumferential groove and the crown circumferential groove includes a pair of groove walls , in a standardized load-applied state where the tire is fitted on a standardized rim at a standardized internal pressure, a standardized load is applied to the tire , and the tire is brought into contact with a flat surface at a camber angle of 0°, the pair of groove walls of the shoulder circumferential groove are not in contact with each other, and at least parts of the pair of groove walls of the crown circumferential groove are in contact with each other, the crown circumferential groove has a widened portion on an inner side in a tire radial direction with respect to a tread ground-contact surface , a groove width (W2) of the widened portion is larger than a groove width (W1) at the tread ground-contact surface of the crown circumferential groove , a band layer including a jointless band ply in which a band cord is helically wound at an angle of 5 degrees or less with respect to a tire circumferential direction is provided inside the tread portion , and the jointless band ply is placed so as to cover the tire equator (C), characterized in that an outer end in a tire axial direction on the first tread end (T1) side of the jointless band ply is located on an outer side in the tire axial direction with respect to an outer end in the tire axial direction of the shoulder circumferential groove . <EOS>
