Good post. Much more detailed than mine. Haha.Indeed
18 inch rim diameter vs 20 inch rim means 1 inch less sidewall, tire diameter for a 285/65R20 is 34.6 so roughly 8.3 vs 7.3 inch (12% change). Plus the tires are both all season so similar rolling resistance.
Cyber vs core are both 20 inch rims and 35 inch tire, but the tread is all season vs all terrain.
Model Y wheels range from 18 to 21 inch rims with 5.1 to 3.8 inches of sidewall (34% change). Sidewall and tread width change, but circumference is within 1.5%, with different tire formulations.
Model S all seasons are 4.5 sidewall on 19s and 3.7 on 21s, 19% change and the 21s are half the sidewall of the Cybertruck 20s.
