It is not so much weight, John.
In 2013 my Morgan garage weighted the black painted spoked rim as the 2010 Roadster sport used it at 8,6 Kg without tyre. This weight is only a few 100 gr away from the Morgan alluminum wheel.
And the 4/4 rim is more narrow and should be even lighter.
The rim of the 2011 Plus4 Supersport weights more than 11,5 Kg including and because of the hub adapter.
The "Image-wheel" rim of the 4/4 80th anniversary should be about 8Kg including their bolt on to center hub adapter.
BTW the Morgan 5 bolt on hub weights about 2Kg more than the hub for the center spoke wheels. The exact numbers are somewhere in the nirvana of an older computer but my garage did measure it for me.
