There is provided a pneumatic tire having a shallow groove provided between zigzag sipes adjacent in the circumferential direction of the tire, a tire mold used for production of the pneumatic tire and a method of producing the pneumatic tire with the tire mold, 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 of the present invention has a tread surface 1 where land portions 6, 8, 12, 13 and 14 are defined by grooves 2, 3, 4, 5, 7, 9 and 10. The land portions 6, 8, 12, 13 and 14 have tread surface sections 6a, 8a, 12a, 13a and 14a, in which a plurality of sipes 15 extending in a zigzag manner in the widthwise direction of the tire are arranged at prescribed intervals in the circumferential direction T of the tire. A shallow groove 16 extends between sipes 15 and 15 adjacent in the circumferential direction T of the tire. The shallow groove 16 is placed such that parts x and x of the land portions sectioned on the opposite sides of the shallow groove 16 are not separated but partially communicate with each other.
