You may calculate the hysteresys losses as a main component of rolling resistance by summation of dissipation energy in volume of tire taking into account the damping ratio of tire material (reinforced rubber). Finite element method is good and useful for this aim because it allows us to take into account the heterogeneous structure of tire and non-uniform distributions of stresses, strains and damping ratio in a volume of the tire.

All the best

Dear Tamil Arasu, besides hysteresys losses, you can determine the rolling resistance component caused by slippage at a frictional interaction of tire with road. Draft estimation using ANSYS software is based on FEM solution of contact problem for the joint "elastic tire - rigid foundation" under driving moment. As was previously mentioned, the frictional losses due to slippage are calculated by summation of dissipation energy in slip zone of the contact. Of course, the value of friction coefficient for rubber at sliding must be known. Good luck!
