A tire manufacturer buys rubber, synthetic or otherwise, with which to make tires. ually these materials will end up in the hands of final users: the owners of the cars. The nature of industrial goods depends on the nature of the goods to be made for final users. The price of industrial goods and raw materials will influence the price of final goods, those that the consumer buys.
