摘要： Disclosed is a pneumatic tire effectively controlling uneven wear occurring in the vicinity of a main groove even if a groove width of the main groove is narrowed due to change in tread radius during inflation. In the pneumatic tire, with regard to a zigzag-shaped main groove having the groove width narrowed during inflation among a plurality of main grooves provided on the tread surface, an inclination angle of a groove wall near the shoulder with respect to the tread surface is made relatively large in a bent portion near the shoulder, an inclination angle of a groove wall near the center with respect to the tread surface is made relatively large in a bent portion near the center, and regions where the inclination angles of the opposed groove walls are different from each other are uncontinuously arranged in the tire circumferential direction.

摘要： Disclosed is a pneumatic tire effectively controlling uneven wear occurring in the vicinity of a main groove even if a groove width of the main groove is narrowed due to change in tread radius during inflation. In the pneumatic tire, with regard to the main groove having its groove width narrowed during inflation among a plurality of main grooves provided on a tread surface, both groove walls are inclined so that the groove width becomes wider toward the groove bottom, and a protrusion dividing the groove space in the tire width direction is provided at the groove bottom.
摘要翻译：公开了一种充气轮胎，其有效地控制在主槽附近发生的不均匀磨损，即使主膨胀槽的槽宽度由于充气期间的胎面半径的变化而变窄。在充气轮胎中，对于在胎面上设置的多个主槽之间的槽宽度狭窄的主槽相对于设置在胎面上的多个主槽之间的槽宽度倾斜，槽宽度朝向槽底变宽，在槽底部设置有将轮胎宽度方向的槽空间分割。
