Tires are a man made product made from Natural Resources.Early tires used natural resources from rubber trees, cottonplants, and sulfur. The cotton was spun into fibers that were usedembedded in uncured natural rubber to strengthen it and the tirewas cured using the sulfur in a process called vulcanization.Modern tires use natural resources from petroleum, iron ore,etc. The iron ore is made into steel which is made into steelfibers that are embedded in uncured synthetic rubber made frompetroleum to strengthen it and the tire is cured.
