tldw:

- wider wheels are marginally less efficient but almost negligible

- rims with larger diameter have larger air resistance. Probably because the rim patterns intersects the air in weird ways but it's not explained. Tire walls are relatively smooth, so tires with higher aspect are way more aero-efficient despite having more marginally lower rolling resistance.
