TIRE

The tire has a tread portion for which an intended tire rotational direction is specified. The tread portion comprises first inclined land portions defined between first inclined grooves. The first inclined land portion comprises an outer portion having a first wall surface and a second wall surface, and an inner portion having a third wall surface and a fourth wall surface. The angle θ of the first wall surface is smaller than the angle θ of the second wall surface, and the angle θ of the third wall surface is larger than the angle θ of the fourth wall surface.
