1. A method for determining pressure within a tire mounted to a vehicle, the method comprising the steps of:

  • sensing a pressure of the tire;

    calculating whether the sensed tire pressure is greater than a predetermined pressure range, within the predetermined pressure range, or less than the predetermined pressure range wherein the step of calculating comprises;

    determining a difference between a stored pressure and the tire pressure and comparing the determined difference to a predetermined pressure difference; and

    providing one of a first combination of audible and visual indications external to the vehicle that the tire pressure is greater than a predetermined pressure range, a second combination of audible and visual indications external to the vehicle that the tire pressure is within the predetermined pressure range, and a third combination of audible and visual indications external to the vehicle that the tire pressure is less than the predetermined pressure range, wherein each of the first, second, and third audible and visual indications are different from one another.
