This often isn't the case with lightweight wheels, at least with regard to the wheel diameter. For a 25-inch wheel/tire combination, if the widths are the same, a 17-inch wheel will have an extra inch of alloy in the combination, but an inch less of sidewall (two sidewalls, actually). So while the wheel itself will weigh more, the tire that goes on it will weigh less -- and the wheel/tire weight sometimes goes down. Put another way, with wheels like Fikses or Fuchs, the additional 'inch of wheel' will often weigh less than the additional 'inch of tire.'
Of course, wider wheel/tire combinations will weigh more, and overall decreases in tire diameter will reduce overall weight.
