A tire pressure indicator for coupling with a valve stem of a tire. The tire
pressure
indicator provides a first visual indication in the event that the tire pressure
is below a first threshold limit and a second visual indication if the tire pressure
is above a second threshold limit. The pressure indicator includes a dome shaped
indicator and a dome shaped cover that is mounted over the indicator. The cover
includes a plurality wedge shaped transparent viewing windows extending from near
the top of the dome. The transparent viewing windows are separated by opaque portions.
The indicator has a plurality of alternating wedge shaped areas of first and second
colors extending from near the top of the dome to the lower peripheral edge of
the indicator. The rotation of the indicator is related to the tire pressure. In
one orientation of the indicator that occurs when the tire pressure is below a
first predetermined limit, the first color is visible through the transparent viewing
windows of the outer dome. In a second orientation of the inner dome that exists
when the tire pressure is above a second predetermined limit, the second color
is visible through the viewing windows of the outer dome.
