A tyre comprising a tread portion having, when the tyre is mounted on a vehicle, an outer tread edge positioned on an outer side of the vehicle and an inner tread edge positioned on an inner side of the vehicle, wherein the tread portion is provided with a plurality of main grooves extending continuously in a tyre circumferential direction, the main grooves include an outer main groove arranged closest to the outer tread edge, an inner main groove arranged closest to the inner tread edge, and a middle main groove arranged between the outer main groove and the inner main groove, each of the main grooves has a pair of groove edges arranged on both sides in a tyre axial direction and extending in the tyre circumferential direction, at least one of the pair of the groove edges includes a plurality of circumferential portions extending in the tyre circumferential direction and a plurality of axial portions inclined at larger angles than the circumferential portions with respect to the tyre circumferential direction, an axial length (w) of each of the axial portions is a length in the tyre axial direction between one end of each of the axial portions and an intersection position where the axial portion intersects with a virtual circumferential portion obtained by smoothly extending the circumferential portion adjacent in the tyre circumferential direction to the axial portion, when a sum of axial lengths (w) of the axial portions included in the main grooves is referred to as an axial portion total length, an axial portion total length L1 of the outer main groove, an axial portion total length L2 of the middle main groove, and an axial portion total length L3 of the inner main groove satisfy an Expression and an Expression shown below: L 1 > L 3 L 1 ≥ L 2 ≥ L 3 and the inner main groove has an inner first groove edge positioned on a side of the inner tread edge and an inner second groove edge positioned on a side of the middle main groove, and each of the inner first groove edge and the inner second groove edge has the circumferential portions (6c, 6d) and the axial portions (7c, 7d), characterized in that in each of the inner first groove edge and the inner second groove edge, the circumferential portions (6c, 6d) include inner first circumferential portions and inner second circumferential portions arranged alternately in the tyre circumferential direction, the inner second circumferential portions are arranged on a side of a groove center line of the inner main groove of the inner first circumferential portions, in each of the inner first groove edge and the inner second groove edge, the axial portions (6c, 6d) include inner first axial portions and inner second axial portions, and from both ends of each of the inner second circumferential portions, a respective one of the inner first axial portions and a respective one of the inner second axial portions extend. the tread portion is provided with a plurality of main grooves extending continuously in a tyre circumferential direction, the main grooves include an outer main groove arranged closest to the outer tread edge, an inner main groove arranged closest to the inner tread edge, and a middle main groove arranged between the outer main groove and the inner main groove, each of the main grooves has a pair of groove edges arranged on both sides in a tyre axial direction and extending in the tyre circumferential direction, at least one of the pair of the groove edges includes a plurality of circumferential portions extending in the tyre circumferential direction and a plurality of axial portions inclined at larger angles than the circumferential portions with respect to the tyre circumferential direction, an axial length (w) of each of the axial portions is a length in the tyre axial direction between one end of each of the axial portions and an intersection position where the axial portion intersects with a virtual circumferential portion obtained by smoothly extending the circumferential portion adjacent in the tyre circumferential direction to the axial portion, when a sum of axial lengths (w) of the axial portions included in the main grooves is referred to as an axial portion total length, an axial portion total length L1 of the outer main groove, an axial portion total length L2 of the middle main groove, and an axial portion total length L3 of the inner main groove satisfy an Expression and an Expression shown below: L 1 > L 3 L 1 ≥ L 2 ≥ L 3 and the inner main groove has an inner first groove edge positioned on a side of the inner tread edge and an inner second groove edge positioned on a side of the middle main groove, and each of the inner first groove edge and the inner second groove edge has the circumferential portions (6c, 6d) and the axial portions (7c, 7d), characterized in that in each of the inner first groove edge and the inner second groove edge, the circumferential portions (6c, 6d) include inner first circumferential portions and inner second circumferential portions arranged alternately in the tyre circumferential direction, the inner second circumferential portions are arranged on a side of a groove center line of the inner main groove of the inner first circumferential portions, in each of the inner first groove edge and the inner second groove edge, the axial portions (6c, 6d) include inner first axial portions and inner second axial portions, and from both ends of each of the inner second circumferential portions, a respective one of the inner first axial portions and a respective one of the inner second axial portions extend.
