I do wonder about the benefits of alloy wheels. There was a recent

Actually alloy does neither. The weight is about the same and alloy is
sometimes even heavier than steel. The use of alloy is more about design
and fashion.

I agree although I think the original alloy wheels 50-60 years ago on
rally cars were to reduce the unsprung weight. Also it does appear that
reducing the unsprung mass does increase cabin noise and vibration which
is not what you want on a normal road car.
