ABSTRACT:
A low tire warning device for pneumatic vehicle tires comprises a flexible stem attached to the vehicle side of a wheel, the stem contains an offset internal expansion chamber which will distort the stem assymetrically when pressurized by the air within the tire. This will displace a metal tip clear of an adjacent rod. If the tire pressure drops this will allow the striking tip driven by the rotating wheel to strike the rod, producing an audible sound warning.
