TIRE

A tire includes a tread and a belt including inner and outer layers and . Each end of the outer layer is located axially inward of an end of the inner layer . A circumferential narrow groove is formed on each shoulder land portion so as to continuously extend in a circumferential direction. A groove width of the circumferential narrow groove is smaller than that of a shoulder circumferential groove . The circumferential narrow groove is located between the shoulder circumferential groove and the end of the outer layer in an axial direction. A ratio of a distance in the axial direction from the shoulder circumferential groove to the circumferential narrow groove to a distance in the axial direction from the shoulder circumferential groove to the end of the outer layer is 15% to 55%.
