Modeling of Rolling Resistance Test Data 980251

This study addresses the issue of modeling laboratory rolling resistance data, collected following standard test procedures. A brief reference to the current method, SAE J1269, and the models used therein, is followed by a discussion on development of new models that also account for the effect of speed on rolling resistance. A model is proposed that represents rolling resistance data over a range of speeds and can be used to predict rolling resistance at various load, pressure, and speed combinations, other than the test conditions. Further, the same model is effective in modeling passenger car as well as light-truck (LT) tire data.
