To provide a tire/wheel assembly which allows for improvement in efficiency of electric power reception in radio electric power supply, and a tire.SOLUTION: A tire/wheel assembly comprises: a wheel comprising a disc portion and a rim portion and having an electric power reception device which is mounted on an inner circumferential surface of the rim portion, and receives electric power supplied by radio from an outside, in a radial direction of the wheel, of the rim portion; and a tire which is mounted to the wheel in such a manner that the tire covers the outer circumferential surface of the wheel, and comprises a pair of bead portions, wherein each of the pair of bead portions has a bead core and a bead filler. When a width, in a tire width direction, of the bead filler at a center position in a tire radial direction is denoted as BFW and the maximum width, in the tire width direction, of the bead core is denoted as BDW, the tire satisfies a relational expression of 0.1≤BFW/BDW≤0.6.SELECTED DRAWING: Figure 3
