Abstract: A tire 1 includes a communication device 10 embedded inside a tire side portion 1d and a plurality of turbulence-generating projections F projecting from a tire outer surface 1ds of the tire side portion, extending along the tire radial direction, and arranged at intervals in the tire circumferential direction. The communication device overlaps at least one of an inter-projection recess G between adjacent turbulence-generating projections and the turbulence-generating projection F in a projected plane of the tire side portion in the tire width direction.
