EVs rarely use brakes, and larger wheels reduce the efficiency of regen braking. But we are optimizing for the worst case where braking is needed, so a larger wheels reduce size is useful.

- matt-attack 11mo agoAvoid vague terms like “size” when talking about a wheel. A car wheel all has a diameter, usually expressed in inches, and a width also usually expressed in inches. It’s not clear to me which dimension folks are saying, has a relationship to brake size. I’m imagining width is the dimension related to wind efficiency, but I would nonetheless ask folks to use more accurate terms like wheel diameter or width.
