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

  • associating wheel inspection data of said vehicles with locations of corresponding wheels in said vehicle;

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

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