Abstract
A method and system for monitoring air pressure or operational status of at least one particular tire of a vehicle facilitates ready identification of a relative mounting position of the particular tire. At least one pressure indicating signal is received (110 of FIG. 8) and is associated with a particular tire mounted at an unknown relative position on a vehicle. Physical parameter data are obtained (112) indicating physical parameter measurements at the different tires of a vehicle. The obtained physical parameter data are evaluated (114) to identify the relative mounting position of the particular tire on the vehicle. Accordingly, an operator of the vehicle may be provided with an indication (130) that an air pressure of a particular tire is less than a proper air pressure so that peak vehicle performance and necessary maintenance may be obtained. Even if the indication informs that the pressure is normal, the operator is reassured that the tires are functioning properly.
