We have a metal scrap yard about 8 miles from my house where they buy scrap metal to sell overseas. Many people bring their old junk cars and trucks there to sell for scrap.
The scrap yard will not take wheels or gas tanks. They lift the car with a forklift while you remove the tires and gas tank and take them back with you.
Most people just drive down the road a block or two and then toss the wheels and tanks on the side of the road.
When I need a spare I just drive up the road and look for one with the same bolt pattern I have and do my part in cleaning up the environment.
