Abstract

Systems and methods for indicating conditions for the appropriate inflation and/or deflation of tires are disclosed. Some systems and methods include measuring a variable affecting the internal gas temperature of a tire, calculating by the processor an estimated internal gas temperature of a tire, and determining whether a tire is appropriate to inflate and/or deflate.

Claims (9)

1. A method for indicating a tire condition comprising:

receiving, by a processor from a sensor, a variable affecting an internal gas temperature of a tire;

calculating, by the processor, an estimated internal gas temperature of the tire based on the variable;

determining, by the processor, whether the tire is appropriate to at least one of inflate or deflate, based on the estimated internal gas temperature of the tire;

displaying, on an output device, a value indicative of whether the tire is appropriate to at least one of inflate and deflate.

2. The method according to claim 1 , wherein the variable affecting the internal gas temperature of the tire includes at least one of a distance traveled on a surface, a frictional coefficient of the surface, a brake temperature, and an ambient temperature.

3. The method according to claim 2 , wherein the ambient temperature includes at least one of a preflight ambient temperature, an ambient flight temperature, and a post-flight ambient temperature.

4. The method according to claim 1 , further comprising that the receiving, calculating, and determining are repeated until a determination that it is appropriate to at least one of inflate and deflate the tire is given.

5. The method according to claim 1 , wherein the output device is in at least one of electrical communication and RF communication with the processor.
