Made a presentation on the matter here:

I have calculated and estimated these will save about 10% of energy on all EVs that are running similar +-5% diameter size tires than what these are. would you be interested to get them for your EV if my calculation will be proved in the coming months correct in the Model Y tests. Same test wheels will be tested also on Model 3, but that car I havent yet found for the tests that will be carried out in Finland. |
* Very often, it's reported that the 'larger' wheels on BEVs come with a 'penalty' to range.
* And a number of researches have confirmed the efficacy of 'aero' wheels as pertaining to range improvements.
* So you're firing on all 'rotors'!

If the numbers pan out, I could see the potential for a 'market.'
Zip-tied cardboard and Coroplast is one thing, but an effective, affordable, OEM 'look' wheel cover might find broad appeal.
The narrower tire section, if it can handle the load rating, is something Mercedes-Benz has exploited on their EQXX concept.
That's 'three boxes' you've checked.
