Thanks for posting up your testing, as usual, Vekke. You've done of the cooler, "Mad Max" style modding and testing on this forum over the years.

One of the things that will make frontal area created by the tire different and more important than just any frontal area is the fact that it is a moving rough surface, a tread that is designed to force away fluids. The tire face must blast air both under the car and maybe a foot or more to the sides, creating an effective frontal area far larger than the face of the tire itself.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.

The trend is to stop using those simple deflectors in front of the wheels.
Something else is being used now, you have two examples here:





You must do the same for the rear wheels.
