Abstract
A tire-wheel assembly includes: a wheel having a rim portion at least part of which is formed of a non-magnetic material; and a tire mounted on the rim portion, in which a tread portion includes a belt formed of a non-magnetic material. The wheel includes, inside the rim portion in a tire radial direction, a container portion that contains a power receiving device that receives electric power supplied wirelessly from outside of the tire in the tire radial direction. The tire includes bead fillers. When BFH represents a radial height of the bead fillers and SH represents a tire cross-sectional heigh, 0.1≤BFH/SH≤0.5 holds true.
