Old Tires Are Safer
I was reading about using old tires and they discussed chemical leaching. One thing they said was that the tires *were* old so that they had had lots of time under adverse condition to oxidize and vent harmful gases and chemicals. That is why new tires smell bad and old ones typically do not. I found this info and a lot more on tire houses at
http://www.touchtheearthranch.com This was in the FAQ section. I'm quoting:
"The surface of used tires has been subjected to years of exposure to oxygen by high speed rotation in the atmosphere. This exposure causes a phenomenon called oxidation. Oxidation 'interlocks' the surface molecules with oxygen and 'out-gassing' (fly-away molecules of synthetic rubber) is considerably limited, if not stopped completely. It's the new tires that stink/outgas, they just need to "rust" for a while, before they are suitable for use as a building material."
