A tire with a designated tire rotation direction, the tire comprising: a plurality of inclined grooves in both halves of a tread surface divided by a tire equatorial plane, the inclined grooves extending inward in a tire width direction from a tread surface edge side, being inclined in an opposite direction from the tire rotation direction, 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 from the tire equatorial plane in the tire width direction is positioned on the tire rotation direction side of a point P2 located 1/4 of the tread half-width from the tire equatorial plane 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 inward in the tire width direction and terminates before reaching the tire equatorial plane; 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; and the tire further comprises a center groove positioned on the tire equatorial plane of the tread surface and extending continuously in the tire circumferential direction. a plurality of inclined grooves in both halves of a tread surface divided by a tire equatorial plane, the inclined grooves extending inward in a tire width direction from a tread surface edge side, being inclined in an opposite direction from the tire rotation direction, 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 from the tire equatorial plane in the tire width direction is positioned on the tire rotation direction side of a point P2 located 1/4 of the tread half-width from the tire equatorial plane 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 inward in the tire width direction and terminates before reaching the tire equatorial plane; 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; and the tire further comprises a center groove positioned on the tire equatorial plane of the tread surface 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 inward in the tire width direction and terminates before reaching the tire equatorial plane; 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; and the tire further comprises a center groove positioned on the tire equatorial plane of the tread surface and extending continuously in the tire circumferential direction.
