PROBLEM TO BE SOLVED: To secure rectilinear stability without altering the structure of a circumferential main groove exerting a large influence on drainage performance. SOLUTION: This pneumatic tire is provided with a bead part 1, a side wall part 2, a tread 3, and a carcass 4 and a belt 5 which reinforces the respective parts. In the tread part 3, a land part 7 is divided by a circumferential groove 6 extending in the circumferential direction of the tread. In the section in the cross direction of the tread, a grounding surface 7a of the land part 7 and the top part 7b which is formed like a curve projecting outward in the radial direction and closest to the contour line 8 of the tread surface extending over the whole of the tread width of the grounding surface 7a are deflected toward one side edge of the land part with respect to the center of the width of the land part 7 in the range of 0.1 to 0.4 times as large as the land part width RW. |
