A tire with a designated tire rotation direction (R), the tire comprising: a plurality of inclined grooves in both halves of a tread surface (T) divided by a tire equatorial plane (C), the inclined grooves extending inward in a tire width direction from a tread surface edge (E) side, being inclined in an opposite direction from the tire rotation direction (R), and being aligned in a tire circumferential direction; and an inter-inclined-groove land portion formed between each pair of inclined grooves that are adjacent in the tire circumferential direction; wherein along a land portion edge of the inter-inclined-groove land portion on the tire rotation direction side thereof, a point P1 located 3/4 of a tread half-width (W) from the tire equatorial plane (C) in the tire width direction is positioned on the tire rotation direction (R) side of a point P2 located 1/4 of the tread half-width (W) from the tire equatorial plane (C) in the tire width direction, and wherein: each inclined groove includes a lug groove and a narrow groove ; the lug groove extends from the tread surface edge (E) inward in the tire width direction and terminates before reaching the tire equatorial plane (C); the narrow groove extends from an inner edge , in the tire width direction, of the lug groove inward in the tire width direction and terminates before reaching the tire equatorial plane (C); and the tire further comprises a center groove positioned on the tire equatorial plane (C) of the tread surface (T) and extending continuously in the tire circumferential direction. a plurality of inclined grooves in both halves of a tread surface (T) divided by a tire equatorial plane (C), the inclined grooves extending inward in a tire width direction from a tread surface edge (E) side, being inclined in an opposite direction from the tire rotation direction (R), and being aligned in a tire circumferential direction; and an inter-inclined-groove land portion formed between each pair of inclined grooves that are adjacent in the tire circumferential direction; wherein along a land portion edge of the inter-inclined-groove land portion on the tire rotation direction side thereof, a point P1 located 3/4 of a tread half-width (W) from the tire equatorial plane (C) in the tire width direction is positioned on the tire rotation direction (R) side of a point P2 located 1/4 of the tread half-width (W) from the tire equatorial plane (C) in the tire width direction, and wherein: each inclined groove includes a lug groove and a narrow groove ; the lug groove extends from the tread surface edge (E) inward in the tire width direction and terminates before reaching the tire equatorial plane (C); the narrow groove extends from an inner edge , in the tire width direction, of the lug groove inward in the tire width direction and terminates before reaching the tire equatorial plane (C); and the tire further comprises a center groove positioned on the tire equatorial plane (C) of the tread surface (T) and extending continuously in the tire circumferential direction. each inclined groove includes a lug groove and a narrow groove ; the lug groove extends from the tread surface edge (E) inward in the tire width direction and terminates before reaching the tire equatorial plane (C); the narrow groove extends from an inner edge , in the tire width direction, of the lug groove inward in the tire width direction and terminates before reaching the tire equatorial plane (C); and the tire further comprises a center groove positioned on the tire equatorial plane (C) of the tread surface (T) and extending continuously in the tire circumferential direction. <EOS>
