Methods of evaluating the performances of tire and vehicle can be divided largely into subjective evaluation and objective evaluation. Both of these methods have their respective strengths and weaknesses. In order to supplement their weaknesses and to maximize their synergic effects various relevant companies are conducting a diverse range of performance correlation researches. In this study correlation research methods that had been used frequently in the past were reviewed and new analytic method capable of quantitatively indicate the differences in the subjective evaluation results and performance levels is presented.
