A tire (Greek πνευματικός on the lung, the air bearing), also called cover in some regions, is a toroidal rubber piece that is placed on the wheels of various vehicles and machines. Its main function is to allow adequate contact for adhesion and friction with the pavement, allowing starting, braking and guidance. The tires generally have reinforcing threads that. Depending on the orientation of these threads, fall in diagonal or radial. The radial type are standard for almost all History [edit] In 1887, Scottish inventor and veterinary surgeon, John Boyd Dunlop developed the first air chamber tire tricycle for her nine-year-old used to go to school for the bumpy streets of Belfast. To resolve the problem by the rattling tricycle Dunlop inflated rubber tubes with an air pump to inflate balloons. After the rubber tubes wrapped with a tarp to protect them and stuck them on the rims of the wheels of the tricycle. Until then, most of the wheels were solid rubber tires, but tires allowed a march noticeably softer. He developed the idea and patented the pneumatic camera on 7 December 1888. However, two years after he was granted the patent, Dunlop was officially informed that the patent was invalid as Scottish inventor Robert William Thompson, who had patented the idea in France in 1846 and in the United States won a battle Dunlop 1847.1 lawsuit against Robert William Thomson, and he defended his patent
