Most people think a tire is just a piece of black rubber but in fact it is a high-tech product. It must be safe, durable, have good traction and be balanced. The rubber compound mixing machine, the "calender," a machine that presses the fabric chord into the rubber, and other equipment used in the process of making a tire require great expense, frequently several hundred million NT dollars.
一般人以為，輪胎，不過是塊黝黑的橡膠皮，但這其實是項高科技產品，得同時兼具安全、耐磨、操控、平衡等功能，製造過程中所需的膠料混練機、簾布上膠機等，皆所費不貲，動輒數億元。
