If you pay shipping, you can have the steel wheel spare and tire off mine. It's never been on the ground. (Tire is GYM dated 2007)
But chances are you want aluminum wheels and a new tire.
Discount tire can sell you both, and they have a large assortment to choose from. You might also find someone who's upgraded from 15s to 16s and willing to sell you the ones removed.
