A tire comprising a tread portion having a first tread edge and a second tread edge, wherein the tread portion is provided with a plurality of circumferential grooves disposed between the first tread edge and the second tread edge and extending continuously in the tire circumferential direction to axially divided the tread portion into a plurality of land regions, wherein the circumferential grooves include a first shoulder circumferential groove positioned on the most first tread edge side among the circumferential grooves, and a crown circumferential groove positioned adjacently to the first shoulder circumferential groove on the second tread edge side thereof, the land regions include a first middle land region defined between the first shoulder circumferential groove and the crown circumferential groove, the first middle land region is provided with a plurality of bend grooves each having a first end and a second end, each of the first ends of the bend grooves is connected to the first shoulder circumferential groove, each of the second ends of the bend grooves is connected to one of the bend grooves which is next in one tire circumferential direction, each of the bend grooves has a first bent portion on the first end side and a second bent portion on the second end side, at which the bend groove is bent, the bend grooves each comprise a first portion extending from the first end to a bent point of the first bent portion, a second portion extending from the bent point of the first bent portion to a bent point of the second bent portion, and a third portion extending from the bent point of the second bent portion to the second end, wherein a bent angle θ1 between the first portion and the second portion at the first bent portion is greater than a bent angle θ2 between the second portion and the third portion at the second bent portion, wherein the first middle land region is provided with a plurality of auxiliary grooves including inner auxiliary grooves extending from the bend grooves toward the crown circumferential groove and terminated within the first middle land region to have terminal ends, and outer auxiliary grooves extending from the bend grooves toward the first shoulder circumferential groove and terminated within the first middle land region to have terminal ends, and ends of the outer auxiliary grooves at the bend grooves are, through the bend grooves, opposed in the tire axial direction to ends of the inner auxiliary grooves at the bend grooves. the tread portion is provided with a plurality of circumferential grooves disposed between the first tread edge and the second tread edge and extending continuously in the tire circumferential direction to axially divided the tread portion into a plurality of land regions, wherein the circumferential grooves include a first shoulder circumferential groove positioned on the most first tread edge side among the circumferential grooves, and a crown circumferential groove positioned adjacently to the first shoulder circumferential groove on the second tread edge side thereof, a first shoulder circumferential groove positioned on the most first tread edge side among the circumferential grooves, and a crown circumferential groove positioned adjacently to the first shoulder circumferential groove on the second tread edge side thereof, the land regions include a first middle land region defined between the first shoulder circumferential groove and the crown circumferential groove, the first middle land region is provided with a plurality of bend grooves each having a first end and a second end, each of the first ends of the bend grooves is connected to the first shoulder circumferential groove, each of the second ends of the bend grooves is connected to one of the bend grooves which is next in one tire circumferential direction, each of the bend grooves has a first bent portion on the first end side and a second bent portion on the second end side, at which the bend groove is bent, the bend grooves each comprise a first portion extending from the first end to a bent point of the first bent portion, a second portion extending from the bent point of the first bent portion to a bent point of the second bent portion, and a third portion extending from the bent point of the second bent portion to the second end, wherein a bent angle θ1 between the first portion and the second portion at the first bent portion is greater than a bent angle θ2 between the second portion and the third portion at the second bent portion, wherein the first middle land region is provided with a plurality of auxiliary grooves including inner auxiliary grooves extending from the bend grooves toward the crown circumferential groove and terminated within the first middle land region to have terminal ends, and outer auxiliary grooves extending from the bend grooves toward the first shoulder circumferential groove and terminated within the first middle land region to have terminal ends, and ends of the outer auxiliary grooves at the bend grooves are, through the bend grooves, opposed in the tire axial direction to ends of the inner auxiliary grooves at the bend grooves.
