1. A tire pressure monitoring system for a wheeled vehicle comprising the following components in electronic communication,a computer located on the vehicle comprising a data processing unit having a microprocessor configured to execute a processing function for retrieving and modifying data retrieved from electrical components on the vehicle and from data storage units;

  • a pressure sensor connected to a wheel and in fluid communication with a pressurized gas contained in a tire mounted to the wheel, where the pressure sensor is configured to transmit gas pressure data indicative of a gas pressure within the tire to the microprocessor; and

    a vehicle position sensor located on the vehicle and in electronic communication with the computer, where the position sensor is configured to track and record the geographic position and movement of the vehicle,wherein the computer has a non-transitory computer readable medium having instructions stored thereon that, in response to execution by the microprocessor causes the microprocessor to collect information from the pressure sensor and the vehicle position sensor, to record vehicle data including outside ambient temperature, computer clock time, vehicle position information, and the gas pressure data, and to further cause the microprocessor provide a user with the reports based on the collected information, where the reports are displayed on a graphical interface,wherein the computer interrogates the pressure sensor after determining that data from the position sensor indicates that the vehicle has been stationary for a predetermined park time, where the predetermined park time is a time that allows the pressurized gas in the tire to reach a temperature equal to the outside ambient temperature.
