To provide a pneumatic tire capable of enhancing the resistance against groove cracking while the water draining performance and the resistance against rib tear are secured.A plurality of circumferentially stretching grooves 50 are formed at the tread surface 11 of this tire,and the groove bottom deepest part center 72 of that one of the grooves 50 which is located between a shoulder rib 41 and a second rib 45 is positioned nearer the second rib 45 than the center line 85 of the groove width W.The groove wall 61 on the side with shoulder rib is connected with the groove bottom deepest part 71 in that condition by the curved surface part 75 on the side with shoulder rib.The groove wall 65 on the side with second rib and the groove wall 61 on the side with shoulder rib are formed so that the angle α of a virtual extension part 80 as virtual tread surface 11 to the groove wall 65 on the side with second rib is smaller than the angle β of the virtual extension part 80 to the groove wall 61 on the side with shoulder rib.As a result,the resistance against groove cracking can be enhanced while the water draining performance and the resistance against rib tear are well secured.
