Aerodynamic wheel cover mounting design

A wheel cover assembly for a vehicle wheel having a wheel rim, the wheel cover assembly comprising:

• a cover body having
• a cover body outer surface,
• a cover body inner surface opposite the cover body outer surface, and
• a cover body outer edge having a cover body outer diameter that is greater than a rib inner diameter of a stiffener rib extending inward from a rim inner surface of the wheel rim and less than an open end flange inner diameter of an open end flange of the wheel rim;
• a cover mounting mechanism operatively connected to the cover body and
• having a locking position wherein the cover mounting mechanism engages the stiffener rib when the cover body inner surface is facing and engaging the stiffener rib and
• a cover locking position wherein the cover mounting mechanism engages the stiffener rib to retain the stiffener rib between the cover mounting mechanism and the cover body and secure the wheel cover assembly to the vehicle wheel,
• wherein the cover mounting mechanism comprises a plurality of locking arms extending from the cover body inner surface, wherein each locking arm comprises:
• a locking arm body extending from the cover body inner surface and having a body proximal end connected to the cover body inner surface, a body distal end opposite the body proximal end, and an inner surface between the body proximal end and the body distal end;
• and
• a tension ring, wherein the tension ring engages the inner surface of each locking arm body and biases the locking arm bodies radially outward.
