Venting the warm radiator air into the area in front of the wheel would create a pressure zone over the wheel, preventing the normal air steam from accessing the wheel's surface, meaning you don't need a smooth wheel cover, since your radiator's flow will basically act as a wheel cover anyway.

Using the warm radiator's airflow to do so would also help warm the tires, creating better traction, as well, although marginally.
