Abstract
A tire/wheel assembly includes a wheel including a disk and a rim, the wheel having a power reception device attached to an inner peripheral surface of the rim to receive electric power supplied wirelessly from farther outward in a radial direction of the wheel than the rim, and a tire attached so as to cover an outer peripheral surface of the wheel and including a pair of bead portions. Each bead portion in the pair of bead portions includes a bead core and a bead filler, and 0.1≤BFW/BDW≤0.6, where BFW is a width in a tire width direction at a central position of the bead filler in a tire radial direction, and BDW is a maximum width in the tire width direction of the bead core.
