Abstract: A tire pressure indicator that is combined with a fill valve. The indicator and the fill valve are coaxial or concentric. The invention may be screwed onto a tire valve stem. The indicator has three bands or sections, each of which is a different color, for indicating whether tire pressure is within a predetermined range, above that range, or below that range. The colors are viewed through a lens, aided by a mirror. A diaphragm pushes the indicator up when pressure rises, while a spring pushes the indicator down when pressure drops. A tire may be inflated or deflated while the invention is mounted on a tire stem. During inflation, the pin in an air chuck at the end of an air hose may depress a valve pin assembly to open the fill valve. A user may deflate the tire by manually depressing the valve pin assembly to release air.
