A tire (1) is a tire in which a circumferential groove (50) and lug grooves (60) are formed. The lug grooves (60) each include an opening portion (60a) opened to a tread end (5e), and extend in a tread width direction from the tread end (5e) to the circumferential groove (50). A groove bottom (52) of the circumferential groove (50) is provided with projection parts (500). The projection parts (500) extend from one of side walls forming the circumferential groove (50) to the other side wall opposed to the one side wall. The multiple lug grooves (60) are formed at predetermined intervals in a tire circumferential direction. In a tread face view of the tire (1), a projection part (500) is provided between a first intersection and a second intersection next to the first intersection in the tire circumferential direction, where an intersection (Pc) denotes a point where a circumferential groove inner line passing through the inside of the circumferential groove (50) crosses a lug groove inner line passing through the inside of each of the lug grooves. |
