Well it is not just the weight of the tire/rim you care about. The rotational moment of inertia is even more important, because you have to spin the wheel up to speed and then spin it down to zero rpm when you stop. You want the least amount of weight located at the maximum diameter. This will vary with each model (style) of wheel, no matter if it is steel or aluminium. Also, if you have never driven in a car which came from the factory with "normal" profile tires, and you put on bigger rims with "low" profile tires, you will discover that the ride is punishing. You will feel every crack in the road and every pebble you run over.

So after all that, it boils down to "It Depends"
