Claims15
A vehicle tire/wheel arrangement comprising:
- a wheel cover fastened to a wheel rim for reducing drag and operating temperatures of a tire/wheel arrangement, wherein the wheel cover is elliptical in cross sectional share and includes an exhaust port defined by an opening in said wheel cover,
- wherein the elliptical cross-sectional shape of said wheel cover creates a low pressure vacuum chamber about the wheel rim and causes air within the wheel cover to accelerate toward the exhaust port.
A vehicle tire/wheel arrangement including a tire, a valve stem, a wheel, and a plurality of nut and bolt assemblies, comprising:
- a wheel cover fastened to the wheel rim by a fastener, wherein the wheel cover is defined by a diameter, a depth, and an elliptically-shaped dome that reduces drag and creates a low pressure by a Bernoulli effect that causes warm air generated by the vehicle in the area of the tire/wheel arrangement to be evacuated from the wheel cover through an exhaust port diameter;
- a bridge section located over the exhaust port diameter;
- a plurality of reflectors;
- and
- a pressure sensor arrangement disposed on the bridge section, wherein the pressure sensor arrangement includes a gauge and a valve arrangement, wherein the valve arrangement includes an intake valve and a valve and hose arrangement connected to the valve stem.
