Abstract: A pneumatic tire includes shoulder lug grooves and narrow grooves. The shoulder lug grooves are positioned outward in a width direction with respect outermost main grooves. The narrow grooves are positioned outward in the width direction with respect to the outermost main grooves, are formed in spaces between the shoulder lug grooves that are adjacent to each other in the tire circumferential direction, and have both ends connected to the shoulder lug grooves. The narrow grooves are formed across the ground contact edges. A relationship W?(D1×0.8) is satisfied, where W indicates a distance between the ground contact surface inner end portions and the outermost main grooves in the tire width direction and D1 indicates a groove depth of the outermost main grooves.

Abstract: A tire comprises a tread portion 2. The tread portion 2 comprises a plurality of first oblique grooves 10A extending obliquely from a first tread edge Te1 positioned on one side in a tire axial direction toward a tire equator C. Each of the first oblique grooves 10A comprises a main body portion 12 extending from the first tread edge Te1 without reaching the tire equator C and a branch portion 13 branching off from the main body portion 12 and extending to cross the tire equator. The branch portion 13 terminates without being connected with other grooves than the first oblique grooves 10A.

Abstract: A tread pattern of a pneumatic tire includes: first inclined grooves having positions located separated from a center line as starting ends and extending in a first direction of the tire circumferential direction; first lug grooves extending from respective ends on the outer side in the tire width direction of the first inclined grooves in the first direction of the tire circumferential direction, and having an angle formed with the tire width direction smaller than an angle formed with tire width direction of the first inclined grooves; second inclined grooves extending from the respective ends on the outer side in the tire width direction of the first inclined grooves in the first direction of the tire circumferential direction; and third inclined grooves extending from respective intermediate points on the first lug grooves in the first direction of the tire circumferential direction.

Abstract: Disclosed is a pneumatic tire including a straight main groove and two wave-shaped main grooves arranged in the center area of a tread, and diagonal grooves arranged in each shoulder area ranging from each wave-shaped main groove to the outer side of the tire, and extending obliquely outward from the wave-shaped main groove to a direction reverse to the tire rotational direction, the rotational direction being specified for the tire. Each diagonal groove is formed to have a convex protruding toward the outer side of the tire, and the extending end portion of the diagonal groove terminates in the shoulder area. Thus, each shoulder area is provided with a non-block pattern in which a land section continues in the tire circumferential direction. Thereby, the pneumatic tire has increased driving stability and uneven wear resistance while substantially maintaining good drainage performance and noise performance against columnar resonance.
