TIRE

The tire has a tread portion 2 for which an intended tire rotational direction R is specified. The tread portion 2 comprises first inclined land portions 7 defined between first inclined grooves 5. The first inclined land portion 7 comprises an outer portion 9 having a first wall surface 11 and a second wall surface 12, and an inner portion 10 having a third wall surface 13 and a fourth wall surface 14. The angle θ1 of the first wall surface 11 is smaller than the angle θ2 of the second wall surface 12, and the angle θ3 of the third wall surface 13 is larger than the angle θ4 of the fourth wall surface 14.
