A tire-wheel assembly includes a run-flat support member disposed on an inner side of a tread portion of a pneumatic tire, wherein the run-flat support member is made from a foamed body and has a height ½ or greater of a cavity height of the pneumatic tire. When an internal pressure of the pneumatic tire is higher than a predetermined air pressure, the run-flat support member does not come into contact with a rim of the wheel, a side portion of the pneumatic tire, or an inner circumferential surface of a bead portion When an internal pressure of the pneumatic tire is equal to or lower than a predetermined air pressure, an inner side of the run-flat support member in a tire radial direction comes into contact with an outer circumference of the rim of the wheel and/or the inner circumferential surface of the bead portion of the pneumatic tire.
