[Green 912]

A simple way to quickly glean forged from cast and not just P car rims. Not 100% but very close. (P car rims the S# and the fox head is the way to go) If the rims are not mounted with tires and are not covered with stick on weights you can hold them by the center hole with one finger and tap the rim with something hard. Forged will ring like a tuning fork and most cast will just give a dull single ring. Sand cast are rough in the inside and pressure cast often have casting nub bumps in the inner surfaces.
