Hate the people that litter the land with tires just to make it 'technical' or some such crap. If you want to do that buy and litter your own land not public spaces.
I think people rolled the tires off from the top and that is where they ended up. The best part is there is a landfill just over the other side of the hill. The area is commonplace for litter. The main access to the area goes dirrectly passed the entrance to the landfill. It's common for people to haul couches, dressers, tv's etc., dump them out on the hills, shoot them up with their guns then leave the items and gun casings behind. Its ugly.
