A wheel and hub cap assembly wherein a cast metal wheel has a hollow hub portion housing the wheel mounting holes receiving studs to secure the wheel of a vehicle with the hub portion forming an annular groove opening radially inwardly relative to the axis of the wheel to receive a hub cap covering the opening. The hub cap has radially extending retaining elements complementary to the groove to support the hub cap relative to the wheel and limit axial inward and outward movement with the retaining elements being substantially the only contact between the wheel and hub cap.
