Smaller wheels highway question?

People claim that bigger and heavier wheels help with highway gas mileage because of inertia

If that’s true, then why are all of the epa highway numbers better with trims that have smaller wheels? Wouldn’t just the city mpg be better and the highway mpg be worse?

So are bigger wheels better or worse for highway mpg?
