Forged car rims are made with a lot heat and a lot of pressure. they are basically pressed into a mold and thus forged rims are about 300% stronger then cast. Also less metal can be used for forged so the rim is lighter. Cast rims are either poured into a mold and let cooled or the molten liquid is vaccumed into a mold, this allows for less air bubbles around the edges. So forged rims are lighter and stronger then cast rims.
