ABSTRACT:
An indicating device adapted to indicate a flat or severely underinflated tire. The device is activated by the enlargement in the diameter of the underinflated tire caused by centrifugal force acting on the tread, and may be especially useful on dual wheels although it will work on others as well. The device includes a contact device which will be contacted by an expanding tire. That contact tilts a switch to cause a circuit to be completed to light a signal lamp in the cab of the truck.
