I guess the way I got rid of 12 truck tires on rims my son left for me to get rid of. The old cistern started to cave in.
put the tires in one end, made a wall to block off,filled in with old gravel to within 18" of top then compost and soil. Now have a very nice 4x4 planter and NO tires. The plants love it. The area was 4x11 when I started. Now have a 4x4 garden, 3ft wide steps to the basement (new entrance) and a 4x4 storage area at lower level. Only cost me 3 bags of mortar for the brick retaining wall made from the pavers used to line the old cistern. The tires act as drainage for the flower bed and below the storage area. Needed that door there for a long time. Easier to put things into and out of basement. I did this when I was 62. If you want something anything is possable.
