4" vs. 6" + 8" Diameter Wheels

Wouldn't this vary somewhat significantly based on the material of the wheel as well as any lightening? I'm sure we could calculate worst case scenarios (solid wheel of aluminum billet) but I'm not sure it would actually be terribly useful. Perhaps assign real materials to the AM plaction/performance wheels and use your CAD program of choice to computer the moments?
