TIRE

A tire 1 includes a first circumferential groove 3, an outer region 2A between an outer tread end To and the first circumferential groove 3, and an inner region 2B between an inner tread end Ti and the first circumferential groove 3. A rubber hardness of a ground-contact surface 2s of the outer region 2A is smaller than a rubber hardness of a ground-contact surface 2i of the inner region 2B. A pitch length P1 in a tire circumferential direction of outer lateral grooves 11 provided on the outer region 2A is larger than a pitch length P2 in the tire circumferential direction of inner lateral grooves 12 provided on the inner region 2B. A groove depth Da at the outer tread end To of each outer lateral groove 11 is smaller than a groove depth Db at the inner tread end Ti of each inner lateral groove 12.
