The invention relates to a tire rolling resistance estimation system. A tire rolling resistance estimation system estimates a real-time rolling resistance coefficient of a tire, and includes a tire sensor unit that measures a tire inflation pressure and a tire temperature. The processor is in electronic communication with the tire sensor unit. A steady state coefficient determination module in communication with the processor determines a steady state rolling resistance coefficient of the tire. A steady-state tire temperature module in communication with the processor receives a steady-state rolling resistance coefficient of the tire and estimates a steady-state tire temperature of the tire. A real-time rolling resistance coefficient module in communication with the processor receives a steady-state tire temperature of the tire and estimates a real-time rolling resistance coefficient of the tire based on the steady-state rolling resistance coefficient and a difference between the steady-state tire temperature and a current tire temperature from the tire sensor unit.
