The tire includes a tread portion provided with a first tread edge, a shoulder circumferential groove, and a shoulder land region. The shoulder land region includes an inner area demarcated axially inside from a center position in the tire axial direction of the shoulder land region, an outer area demarcated axially outside from the center position, and a plurality of shoulder axial grooves extending in the tire axial direction at least in the outer area. In a standard tire load loaded state, an average ground contact pressure in the outer area is larger than an average ground contact pressure in the inner area.

Tire

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 L, L, and Lof the outer main groove, the middle main groove, and the inner main groove, respectively, satisfy Expressions (1) and (2) shown below;1&#x3e;3&#x2003;&#x2003;Ex. (1)1&#x2265;2&#x2265;3&#x2003;&#x2003;Ex. (2).
