ABSTRACT:
Tire pressure-indicating gauge is mounted at the center of a spoked wheel for a pneumatic tire to continuously monitor and display the tire's air pressure. The pneumatic tire is mounted on the rim of wheel, and pressurized air may be selectively introduced to, and captured within, the pneumatic tire via a common rim-mounted valve stem. Air pressure within the pneumatic tire is communicated to the pressure-indicating gauge via a hollow channel disposed within one of the spokes of the wheel, on the opposite side of the wheel from the valve stem. The pressure-indicating gauge is secured within a recess in the hub of the wheel in an air-tight fashion. The hollow air channel is preferably molded or cast into a spoke in such a manner that there is little or no outwardly visible physical difference between the various spokes of the wheel.
