Automotive organizations are paying their major interest in the weight reduction of components to minimize fuel cost. This weight can be reduced by introducing new materials and manufacturing processes with optimization of design. Minimizing the weight in the wheel is more effective than minimizing the weight in other components because of its rotational moment of inertia effect during its motion and also the tyre take the overall vehicle load and provides cushioning effect. By reducing the weight we can achieve the objective the reducing of unsprung mass, by which the inertia loads and overall weight are reduced with improvement of performance and fuel economy. In this paper an attempt is made to minimize the weight of the wheel by replacing the aluminium alloy with composites. From the finite element calculations it is found that the mass of the wheel rim can be reduced to 50% from the existing alloy wheels. The analysis also shows that after the optimization the stresses generated from the wheel rim will be below the yield stress. This gave a new approach in the field of optimization of passenger car wheel rim. In this work the modelling is done by using CATIA V5 R20 and analysis is made by using ANSYS15.0.
