Wheels as a vital part of a vehicle or engine, first discovered by the Sumerians in 3,500 years BC. In Mesopotamia, also found a round object with the middle, which allegedly make pottery from the same period. This proves that at that time people began to know the working principle of circular motion.

Furthermore, in 3000 BC, trains began to be known in Assyria, then continued in the Indus Valley. Medium Mainland and Central Europe only knew strollers around 1000 BC, even new English in the year 500 BC. In 1515 people found wheel-keys, wheels that could be rotated and stopped by a wedge object. This principle was then developed into a bomb-burning wheel - and a match.

The engineering world is greatly helped by the Invention Wheel. From ice cream machine to hydropower, menis sew up to the shuttle, bike ride to formula racing car. Wheel wheels as vehicle propulsion then can not be separated from prohibition logging, which is determined by the role of Robert William Thomson and John Boyd Dunlop. For example the ban coded 215/65R15 89H. The number '215' is the width of the tire's palm in units of millimeter size. '65' (Aspect Ratio), is the ratio/thickness between the thickness of the tire profile and the width of the ban. The number 65 here is a high prohibition/ban is 65% of the width of the ban.

Functions. Holding the entire weight of the vehicle. Moving power to the road. Move the braking force to the road surface. Make the steering system work. Reduce the effects caused by uneven road surfaces.

Carcass is a hard tire frame, serves to withstand high pressure air, but flexible enough to stretch the load and impact. Performance tread to protect carcasses against wear and damage caused by the road surface. The side wall is a rubber layer that blocks the side of the tire and protects the carcass against damage from the outside. The breaker between the carcass and the tread that produces the adhesion, and dampens the shock from the surface of the path to the carcass. How to work to prevent tire rupture from the rim by because of the various styles that work.
