Abstract
A tire includes having a tread portion that has three land portions defined by two crown main grooves that continuously extend in a tire circumferential direction and that are arranged across a tire equator. The three land portions include two shoulder land portions. At least one of the shoulder land portions includes a plurality of main inclined grooves that extend so as to be inclined. At least one of the main inclined grooves has an inner end and an outer end. The main inclined groove has a steeply-inclined portion that extends so as to be inclined from the inner end toward a tread end, and a gently-inclined portion that extends across the tread end from the outer end at an angle, relative to an tire axial direction, which is less than an angle of the steeply-inclined portion relative thereto. A length of the steeply-inclined portion is greater than a length of the gently-inclined portion.
