The person writing that article has made a guestimate in stating that. As the article has already stated "The further from the center, the higher the MoI." It is incorrect to make this blanket statement: "Given that each pound of rotational mass lost provides an equivalent performance gain as a 10 pound reduction in vehicle weight". One would have to calculate the angular momentum on a particular rim/tire combination before making such a statement.
