With so many cars in California, trashed tires can become a common eyesore.

A few tires were found littering the ground in Costa Rica.

Here and there in the country of Nicaragua were found trashed tires.

The materials of modern pneumatic tires are synthetic rubber, natural rubber, fabric and wire, along with carbon black and other chemical compounds. They consist of a tread and a body. The tread provides traction while the body provides containment for a quantity of compressed air. Before rubber was developed, the first versions of tires were simply bands of metal fitted around wooden wheels to prevent wear and tear.[from wikipedia]

A single trashed tire was found in San Juan del Sur.
