Good idea. NOT!!!
Remember that tire fire in Canada a few years back. That sucker smoldered and belched oily smoke for months and months.
Stacked this way, they would burn fast, plenty of access to air.
No I don't remember that. I heard that Canadian tires are square. Is that true.
I heard that there is a coal mine fire in China that has been burning for decades. That it puts out as much pollution as all the cars in the US. Of course, that was Art Bell.
