PROBLEM TO BE SOLVED: To provide a pneumatic tire including a resonance groove extending along a tire circumferential direction, and easily ejecting bit stones and the like. SOLUTION: The pneumatic tire 1 includes the resonance groove 20 extending from a side 15a of a groove 15 in a circumferential direction on the end side in the tire circumferential direction, and of which the end 22a closes in a land part 23, and a rib 30 continuously extending along the roughly center of the groove width is provided at the resonance groove 20. The rib 30 has one end 30a jointed to the sidewall 25 on the closed-end side of the resonance groove 20, and the other end 30b ending in the mid way in the resonance groove 20. The height H1 of the rib 30 on the other end side is set to be lower than the height H0 on the one end side. COPYRIGHT: (C)2011,JPO&INPIT |
