ABSTRACT:
The present invention is directed to a low tire pressure warning device which includes a housing, a bladder and/or spring loaded piston within the housing and a colored warning streamer. The housing has an elongated chamber, one end of which communicates with the interior of the tire and the other with the exterior of the tire. In one embodiment, a bladder is mounted within the chamber of the housing so as to expand and contract in response to tire pressure increases and decreases. The bladder, upon contraction, axially moves a spring-loaded piston so as to "pop out" the colored warning streamer. In another embodiment, a closely fitted spring-loaded piston without the bladder responds directly to changes in the tire pressure and spring motivates the colored warning streamer.
