1. A method for extracting changes in characteristics of a tire supporting a vehicle, the method comprising the steps of:
extracting selected tire characteristics from at least one sensor mounted on the tire;
transmitting the selected tire characteristics to a remote processor;
storing the selected tire characteristics in a historical data log in communication with the remote processor;
selecting at least one tire characteristic of interest;
applying a time series decomposition model to data from the historical data log to delineate exogenous inputs from an underlying trend in the selected tire characteristic of interest;
applying a learning model to the underlying trend in the selected tire characteristic of interest to model a relationship between the selected tire characteristic of interest and a condition of the tire; and
outputting from the learning model a prediction value for a condition of the tire.
