1. An apparatus for tuning a parameter of a Kalman filter in a wheel inspection for a vehicle, comprising:

  • an association module that associates wheel inspection data of said vehicle with locations of corresponding wheels in said vehicle;

    an evaluation module that evaluates a wheel stable score of said vehicle based on said wheel inspection data and said association, wherein said wheel stable score indicates reliability of the wheel inspection, the wheel stable score calculated according to a wheel diameter differential of left and right wheels coupled to a common axis; and

    a parameter tuning module that dynamically tunes a measurement error covariance (R) of said Kalman filter according to said evaluated wheel stable score.
