there are light 15' steelies. and heavy 18' aluminum rims. the rims in that pic look like a cheap show brand rim, so im guessing they tip the scale at over 20 lbs if they are 17's. cast aluminum requires more metal to keep good strength than fordged or semi forged. 3 piece fordged rims are ideal because they can make each part of the rim that provides stregth(outer part that holds the tire, the middle part thats the "spokes", and the center peice where the lugs bolt) the strongest and lightest possible, then connect them all.
