摘要： A tyre includes a tread portion provided with an outer main groove, an inner main groove, and a middle 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 a tyre circumferential direction. At least one of the groove edges includes circumferential portions extending in the tyre circumferential direction and axial portions inclined at larger angles than the circumferential portions with respect to the tyre circumferential direction. When an axial portion total length is a sum of axial lengths of the axial portions included in the main grooves, an axial portion total lengths L1, L2, and L3 of the outer main groove, the middle main groove, and the inner main groove, respectively, satisfy Expressions (1) and (2) shown below; L1>L3 Ex. (1) L1≥L2≥L3 Ex. (2).
