Abstract
A pneumatic tire having two main grooves in the tread that are provided symmetrically with the equatorial plane of the pneumatic tire and which extend in the circumferential direction of the pneumatic tire. The tread is divided into a central portion formed between the main grooves and shoulder portions formed outward of the main grooves in the direction of tire's width. Each of the central and shoulder portions is provided with a plurality of lateral grooves that extend in the direction of tire's width. The lateral grooves in the central portion and those in each shoulder portion are inclined in opposite directions with respect to the axial direction of the tire. All walls of the central lateral grooves are inclined in the same direction with respect to a line in the radial direction of the tire. All walls of the shoulder lateral grooves are inclined in opposite directions to the walls of the central lateral grooves with respect to a line in the radial direction of the pneumatic tire.
