To measure tire rolling resistance, majority of the industry uses two methods, ISO 28580 and SAE J1269. Differences of test procedures between them result in tradeoffs in measurement time and coverage. ISO 28580 requires 2 hours per tire measurement and it only can represent resistance under limited driving condition. on the other hands SAE J1269 requires 4 hours per tire but can represent resistances under various axial loads and pressures. Thus there has been a requirement to estimate various resistances by using simpler resistances. This study describes an optimized method to estimate tire resistance measured on SAE J1269 by using tire resistance measured on ISO 28580. This paper suggests building linear regression models between ISO 28580 and SAE J1269 on several areas separated by axial loads and tire pressures. The suggested method showed R2 of 0.9 and mean absolute error of 0.1.
