Tire fires are a nasty business, and in Kuwait yesterday, a fire broke out at a dump that held more than 5 million tires. The fire was so big that the smoke plume was visible from space:

A tire fire this big is an environmental disaster. It won’t just pollute the air with hazardous materials — it will create a small oil spill as well. Burning just one passenger car tire can produce two gallons of oil, according to the EPA, and 5 million tires could spill about 275,000 gallons of oil on the ground.

In the U.S. some states actually burn scrap tires for fuel, but it’s also possible to recycle them. The worst thing to do with a whole bunch of used tires is pile them up and hope they don’t catch fire. That’s a lesson Kuwait is learning the hard way.
