  • Patent number: 10843509
    Abstract: The purpose of the present invention is to improve running performance in rocky areas. Provided is a pneumatic tire in which is formed a shoulder block in which first shoulder blocks and second shoulder blocks are alternately aligned. Each first shoulder block has a first edge that is on the outer side in a tire axial direction of a tread surface of the first shoulder block. Each second shoulder block has a second edge that is positioned on the outer side in the tire axial direction of a tread surface of the second shoulder block and more toward the inner side in the tire axial direction than the first edge.

  • Patent number: 8443855
    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.
