John Dunlop and Charles Goodyear: The Inventors of Tires
Goodrich also invented the first synthetic rubber tires in 1937 made of a patented substance called Chemigum. The first snow tires for passenger cars, Hakkapeliitta, was invented by a Finnish company (now Nokian) in 1936. The tire is considered one of the best in the industry and is still in production today.

Tweel
The Tweel consists of a band of conventional tire rubber with molded tread, a shear beam just below the tread that creates a compliant contact patch, a series of energy-absorbing polyurethane spokes, and an integral inner hub structure. Both the shear beam and the polyurethane spokes can be designed to provide a calibrated directional stiffness in order to control both how the Tweel handles and how it handles loads.

How tire is made - material, history, used, processing
Tires for most vehicles are pneumatic; air is held under pressure inside the tire. Until recently, pneumatic tires had an inner tube to hold the air pressure, but now pneumatic tires are designed to form a pressure seal with the rim of the wheel. Scottish inventor Robert Thomson developed the pneumatic tire with inner tube in 1845, but his design was ahead of its time and attracted little interest.

Tire
Pneumatic tires also have a much lower rolling resistance than solid tires. Because the internal air pressure acts in all directions, a pneumatic tire is able to "absorb" bumps in the road as it rolls over them without experiencing a reaction force opposite to the direction of travel, as is the case with a solid (or foam-filled) tire.
