Zusammenfassung:	A tyre has a tread portion provided with a rib (4). The rib is provided with a lateral groove (5) extending so as to completely cross the rib. The lateral groove (5) includes a first curved portion (6) and a second curved portion (7). The first curved portion (6) extends from a first end (5e) in a curved shape convex in a first direction in a tyre circumferential direction. The second curved portion (7) extends from the second end (5i) in a curved shape convex in a second direction in the tyre circumferential direction. A groove width (Wa) of the first curved portion (6) is gradually increased over the entire length thereof as it goes toward the first end (5e), or a groove width (Wb) of the second curved portion (7) is gradually increased over the entire length thereof as it goes toward the second end (5i).
