Abstract
A pneumatic tire includes a shallow groove provided between zigzag sipes adjacent in the circumferential direction of the tire, which can reduce production cost of the mold, facilitate trimming operation and decrease waste from trimming while reduction of driving stability during turning on a wet road surface and occurrence of curing trouble are suppressed. The pneumatic tire has a tread surface where land portions are defined by grooves. The land portions have tread surface sections, in which a plurality of sipes extending in a zigzag manner in the widthwise direction of the tire are arranged at prescribed intervals in the circumferential direction of the tire. A shallow groove extends between adjacent sipes. The shallow groove is placed such that parts of land portions sectioned on the opposite sides of the shallow groove are not separated, but partially communicate with each other.
