Pneumatic Tyre (Tire).

John Boyd Dunlop (1840-1921) was a Scottish veterinarian and the recognized inventor of the first practical pneumatic or inflatable tyre/tire. His patent was for a bicycle tire, granted in 1888. However, Robert William Thomson (1822 - 1873) invented the actual first vulcanised rubber pneumatic tire. Thomson patented his pneumatic tire in 1845, his invention worked well but was to costly to catch on. Dunlop's tire patented in 1888 did, and so he received the most recognition. William Thomson also patented a fountain pen (1849) and a steam traction engine (1867).

The materials of modern pneumatic tires are a synthetic rubber, natural rubber, fabric and wire, along with carbon black and other chemical compounds. They consist of a tread and a body. The tread provides traction while the body provides containment for a quantity of compressed air.
