Patent number: 8443855Abstract: 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.Type: GrantFiled: September 22, 2008Date of Patent: May 21, 2013Assignee: The Yokohama Rubber Co., Ltd.Inventor: Kenji Yamane
