Internal Ductwork
I would think that you would want to separate the air that is escaping from the radiator to the outside world, from the air that going twice the surface speed of the road at the top of the tire! Picture 2 really brings this home.
If your going to vent radiator air at this particular location, then a baffle between the vented air and the top of the tire would be very beneficial.
Without that, you will have one heck of a parasitic load from all the air churning about in that location.
