ABSTRACT OF THE DISCLOSURE A wheel problem detecting and warning device for wheeled motor vehicles, comprising tire pressure detecting valves, an air horn and a plunger unit to be mounted on each wheel, the tire pressure detecting valves being adapted to allow air from the tire to be supplied to the air horn to produce a warning sound when the tire is over - or under-inflated. In the meantime air is also supplied to a plunger unit which is then caused to activate an electrical switch mounted on the wheel axle housing to flash a warning lamp provided in the vehicle. The wheel is further provided with a dog member fixedly mounted on the wheel rim to activate the electrical switch when the wheel wobbles as a result of loosening of the wheel bolts or failure of the wheel bearing.
