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 Rim The rim is the piece, usually metal, that sits on a tire. In countries like Mexico and Guatemala is considered the tire rim and the metal wheel and rim. It is a rounded, usually with openings to achieve lightness while allowing airflow. You can find a tire on vehicles such as cars, motorcycles, trucks, airplanes and bicycles.
