1. A method for monitoring a measured tire parameter comprising the steps:

  • a. identifying tire air pressure as a monitored tire parameter;

    b. measuring the tire parameter;

    c. formulating an analytic system strategy for an evaluation of the tire parameter based upon a plurality of analytic systems, the strategy formulation selecting between the use of a single analytic system and, in the alternative, the simultaneous parallel use of a plurality of analytic systems;

    d. selecting at least one analytic system for evaluating the tire parameter measurement from the plurality of analytic systems, wherein selecting at least one analytic system comprises the steps;

    establishing a non-zero minimum leak rate limit (RateLimit);

    establishing a non-zero low pressure threshold difference band (Low Pth);

    measuring a leak rate (k); and

    using an analytic system optimally suited for the measured leak rate;

    e. analyzing the measured tire parameter by means of the selected analytic system; and

    f. communicating a conclusion based upon the analysis of the measured tire parameter.
