A resonator is formed in an intermediate land portion partitioned between the first circumferential main groove and the second circumferential main groove. The resonator has an auxiliary groove whose both ends terminate within the intermediate land portion. The groove depths D1 of the first and second circumferential main grooves are 50% or less of the groove widths W2 of the first and second circumferential main grooves, respectively. The groove depth D3 of the auxiliary groove of the resonator is 70% or more of the groove depth D1 of the first circumferential main groove.",
