Some erasers have rubber(natural or synthetic). The rubber is made from rubber trees. It also contains styrene, buadience, sulpher, vynil, colorants( to get it the color you want like green for example), pumice, and vegetable oil.
Tires are a man made product made from natural resources. Early tires used natural resources from rubber trees, cotton plants, and sulfur. The cotton was spun into fibers that were used embedded in uncured natural rubber to strengthen it and the tire was 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 steel fibers that are embedded in uncured synthetic rubber made from petroleum to strengthen it and the tire is cured.
Things that use rubber (and also synthetic rubber) include: tires, erasers, rubber bands, seals, gaskets, rollers, machine belts, cushioning pads, electrical insulation, bouncing balls, sports balls, and tool grips.
