A tire (rubber or customary) is a ring-shaped casing which is mounted on a wheel rim to protect it and ensure adherence to the road wheel, and to provide cushioning while driving a vehicle. The materials they are made of modern tires are synthetic rubber, natural rubber and various fabrics that certain nichiban chemicals in their composition composed. A tire is composed of two distinct parts, the body and tire tread. Tread ensure adherence to the ground while the body ensures support to the tire, so that it can be fixed to the rim. Before the invention of the tire (tire) were simply used some metal bands that were mounted on wooden wheel wear and to prevent its deterioration. It can meet the carts today. In modern nichiban times the majority of tires are inflatable structures, similar to a donut, which are filled with air either directly or through a room. The tires are used on many types of vehicles such as cars, bicycles, motorcycles, trucks, and aircraft. nichiban
The earliest tires were bands of iron (later steel), placed nichiban on wooden wheels, used on carts and wagons. Predecessor tire was heated in a forge, located on the wheel and cooled, the metal contracts and fit perfectly on the wheel. For this pretty skilled operation was required, nichiban usually fulfilling Demandees blacksmith work. This methodology provided a wear resistant surface wooden wheel. The word "tire" originally appeared as a variable nichiban to refer to the metal bands used to "Boots" wheels. The first pneumatic tire was made by John Boyd Dunlop, who, though working as a veterinarian in Belfast, Ireland, in 1887 his son made the first bicycle tire. He built this tire to prevent the headaches his son on rough roads due to jolts.
Although there is controversy surrounding the appointment of the first inventor of the pneumatic tire (according to some it would be Scot Robert William Thomson), Dunlop is designated as the first made a "rubber could withstand the wear and resilience that keeps the road wheel ". Regarding vulcanization (bonding) natural rubber, is attributed to Charles Goodyear and Robert Thomson William.Primele synthetic rubbers were invented in Bayer laboratories since 1920.
Today over 1 billion tires are produced annually in over 450 tire factories, being the largest consumer of natural nichiban rubber. A forecast for 2015, for example, nichiban shows that will be produced nearly two billion tires. The tire is recnent material for producing butadiene-styrene. In 2010 they sold tires worth over 140 billion dollars, nichiban and the top five most popular manufacturing companies by revenue are Bridgestone, Michelin, Goodyear, Continental and Pirelli.
The tread is the part of the tire that comes in contact with the road surface. The tread pattern is characterized by the geometrical shape of the teeth. These grooves are necessary to ensure the channeling of water when it rains and prevent aquaplaning. Hydroplaning is a phenomenon of flotation tires on a flat surface nichiban covered by a thin layer of water. Another attribute of the tread is to reduce noise levels to reasonable values during walking. High performance tires have small values of the ratio between the inside surface of the tire and the hollowed proemineta to provide the best grip and traction, but are usually made of a softer rubber, resulting nichiban in more rapid deterioration band rolling. There are nowadays nichiban tires for different driving situations, depending on the season or road type. There is for example the snow and mud tires (generally used in winter), the usual summer and obviously the universal or mixed. It is always preferable to use a specific tire than a mixed one as they cope in normal conditions although both winter nichiban and summer, in conditions nichiban of low or very high temperatures are not as safe to use.
