Abstract
An earth-friendly tire using raw materials derived from non-petroleum resources instead of all or part of raw materials derived from petroleum resources currently used for tires. The tire is prepared by using a natural rubber instead of a synthetic rubber; an inorganic filler and/or a biofiller instead of carbon black; vegetable oil instead of petroleum oil; and natural fiber instead of synthetic fiber so that the tire comprises a non-petroleum raw material in an amount of at least 75% by weight based on the total weight of the tire.
