nah the tyres give "free" energy into the system, thats why they get burnt - all that rubber and petroleum based binders etc gives extra heat :) and at the end they get the steel back from inside the tyre (radial belts).

Pretty well all general purpose steels these days are made from a significant percentage of scrap. I am told the scrap is shredded into small pieces and magnetically sorted to get most of the crud out before being fed into the furnaces. I think the temperatures involved would destroy most anything unwanted. The steelmaking processes can be tightly controlled as to alloying content. Specialty steels are generally made from virgin ore. I know from working briefly in a foundry long time ago that virgin pig costs a premium over pig with scrap content.
According to AutoSpeed.com, a VL Commodore 15 x 6 steel rim weighs 9.5 kg. (And a factory Calais 15" alloy weighs 8 kg.)

Typo- should have been $250. Our local paper has a guy advertising he will pick up "six cylinder cars" and pay $100 for them.
