TIRE

A tire has a tread portion bound with an intended tire rotational direction (R); the tread portion includes a first tread edge (T1) and a second tread edge (T2); the tread portion is provided with first oblique grooves (6) extending obliquely toward a heel side in the tire rotational direction from the first tread edge toward a tire equator side, second oblique grooves (7) extending obliquely toward the heel side from the second tread edge toward the tire equator side, and first circumferential grooves (9) each connecting a respective pair of the first oblique grooves adjacent to each other in a tire circumferential direction; the first oblique grooves (6) have the tire equator side end portions intersecting with the second oblique grooves (7); the second oblique grooves have the tire equator side end portions intersecting with the first oblique grooves; the first circumferential grooves (9) have groove widths each increasing toward the heel side in the tire rotational direction.
