Final Project: Tires Industry
Tires are used on all types of vehicles, from cars to earthmovers to airplanes. Tires enable vehicle performance by providing for traction, braking, steering, and load support. Tires are inflated with air, which provides aflexible cushion between the vehicle and the road that smooth out shock and provides for a comfortable ride quality. Tires are pneumatic enclosures used to protect and enhance the effect of wheels.
The first tires were bands of iron, placed on wooden wheels, used in carts. The tire would be heated in a forge fire, placed over the wheel and quenched, causing the metal to contract and fittightly on the wheel. The tire then provided a wear-resistant surface to the perimeter of the wheel. This work was done by a skilled craftsman, known as a wheelwright. The first practical pneumatic tire was made by the Scot John Boyd Dunlop for his son's bicycle
The pneumatic tire also has a more important effect of vastly reducing rolling resistance compared to a solid tire. Because theinternal air pressure acts in all directions, a pneumatic tire is able to absorb lumps and bumps in the road as it rolls over them without experiencing a reaction force opposite to the direction of travel.
Pneumatic tires are made of a flexible elastomer material such as rubber with reinforcing materials such as fabric and wire. Tire companies were first started in the early 20th century, andgrew in tandem with the auto industry. Today over 1 billion tires are produced annually, in over 400 tire factories, with the three top tire makers commanding a 60% global market share.
