What do people do with their original rims when they get mags for their car?
Depending on where you live… lots of people keep them and put them on in the winter… salt and sand are horrible on wheels, and it keeps you rims in good condition to take them off and have snow tires for the winter. Otherwise, sell them on ebay, craiglist, or take them down to the junkyard and just get rid of them, they might give you a couple bucks.
