The analysis of tires is of importance in tire industries for determining wear phenomena, endurance and noise effects, etc. The relative kinematics framework based on ALE formulation has its main advantages in implementing the detailed contact analysis with local mesh refinement and time independent formulation of elastic stationary rolling. The weak point of the ALE formulation is that tires with detailed tread pattern cannot be simulated due to its axi symmetric constraint. To overcome this problem , the ALE coupling as shown in Fig is suggested in the literature . In this method the tread blocks are segregated from the tire body such that the tire body is treated in ALE framework and the tread pattern in transient dynamic Lagrangian manner. Finally the tread pattern is coupled with the ALE tire structure using kinematic constraints at the interface.The advantage of such coupling will complete the whole picture of treaded tires simulation in ALE framework.
