Some ecomodders may inquire about the choice of the wheel cover mock-ups that were trialed. After reading a number of scientific articles, I decided to test the "open center - thick perimeter" wheel studied by Vdovin in 2013 and the "open perimeter" reported by Julian Edgar in his book and some ecomodder that fabricated some for his Tesla.
Vdovin, Alexei, in 2013 also commented on the results experienced in a wind tunnel with these types of wheels :
It is not fun to read an engineering thesis but Tesla came to the same results that were well summarized by Vdovin. He was supported in his research and working with engineers and aerodynamicists of Volvo. The people of this company sometimes come up with great ideas and innovations.
Cheers ecomodders!

Facts, please, give me the facts! Theoretical knowledge is verified by empirical knowledge! Check Einstein's General Relativity Theory E=MC^2! Every few years some new astrophysics observation and data prove some of Einstein's theory predictions more than a century old.
