Abstract

A pneumatic tire. A central circumferential main groove is disposed to extend along a tire circumferential direction, along a ground contact center line of tread of the pneumatic tire. Inboard side circumferential main grooves and inboard side lateral main grooves, which are continuous with the central circumferential main groove, are provided at an inboard side of the ground contact center line. Outboard side lateral main grooves, which are continuous with the central circumferential main groove, and outboard side slanted longitudinal main grooves, which are continuous with the outboard side lateral main grooves, are disposed at an outboard side of the ground contact center line. Thus, irregular wear of land portions is continuously suppressed and controlling stability is improved. Moreover, water at the ground contact center line, which water is difficult to drain, can be efficiently drained from the ground contact area due to less water resistance. In short, the present invention enables a pneumatic tire with improved tire wear resistance, high wet condition drainage ability and improved controlling stability.
