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

    【課題】無線給電における受電効率を向上可能な、タイヤ・ホイール組立体及びタイヤを提供する。【解決手段】タイヤ・ホイール組立体は、ディスク部とリム部とを備えるホイールであって、前記リム部の内周面に取り付けられ、前記リム部よりも前記ホイールの径方向外側から無線によって供給される電力を受電する、受電装置を有する、ホイールと、前記ホイールの外周面を覆うように取り付けられ、一対のビード部を備えるタイヤであって、前記一対のビード部のそれぞれは、ビードコアとビードフィラとを有し、前記ビードフィラのタイヤ径方向中央位置におけるタイヤ幅方向の幅をBFWとし、前記ビードコアのタイヤ幅方向の最大幅をBDWとするとき、0.1≦BFW/BDW≦0.6を満たす、タイヤと、を備える。【選択図】図3
