Abstract
There is disclosed a toy balloon tire and a wheel. The wheel is an assembly of two hub members each having a peripheral rim about its outer end. An annular land is provided between the opposite ends, and a through passageway is provided in one hub member communicating with a port discharging into the tire. A valve is provided to seal the passageway. The balloon tire has a central opening in one of its sidewalls which is surrounded by a bead. The bead is received over the hub of the wheel and is seated against an annular rim of one of the hub members. The wheel can have a mechanical valve member mounted in the through passageway. Alternatively, the tire itself can seal the passageway and function as the valve. In the preferred embodiment, the passageway discharges into the interior of the tire through a port which is located in the annular land of the hub, between its opposite ends. When the tire is placed on the hub, the annular skirt of the tire overlies the annular land of the hub and functions as a valve member. Pressure relief passageways can be provided which extend through one of the hub rims and open into the annular land of the hub. The tire can be inflated by the application of air pressure to the through passageway. Once inflated, the air is retained in the tire of the valve. In the event the tire is overinflated, it expands sufficiently to uncover the relief passageways, and relieve the excessive pressure.
