What is Tyre

According to Wikipedia:
Tire (American English) or Tyre (British English; spelling difference ;) is an annular ring-shaped part that moves around the wheeled rim from the wheeled vehicle to the ground and cleans the surface.

Many Tyres, such as cars and bikes, are pneumatic equipment, which also provides a shock-absorbing cap on the skirt surface. The Tyres provide the impression that the vehicle complies with the mass of a heavyweight mass.

Pneumatic materials are synthetic, rubber, tissue and metal, black and other chemicals. They have head and body mass. The instructions are attractive when there are insecticides for many of the body's air defects. Prior to rubber, the first source of Tyre is used to paint metal around the Tyre to prevent wear.

The first tanks of the courts were strong (not pneumatic). Air burns many types of cars, bicycles, cars, buses, Lorries, automobiles and cars used in cars. Iron Tyres are still being used in electric and cars, and heavy letters (or other tablets) are used in various vehicles, such as other badges, cotton, string and cotton.
Exports and handwriting

The word Tyre is a short form of clothing from the idea that a Tyre wheel is a plausible wheel.

Spelling Tyres first appeared in the 1840s, when the British began to reduce the landing of the wheels of railway wagons with spheroidal graphite. The traditional publishers, however, continued to rely on tyres. The British newspaper Times used tyres as early as 1905 and in the 19th century in Great Britain began to use magic tyres extensively for pneumatic tyres.

The Encyclopaedia Britannica of 1911 states that "the tyre is not recognised by the best English authorities and is not recognised in the United States", and Fowler's Modern English of 1926 says that "there is nothing to say about the tyre", which is etymologically incorrect and also unnecessary, differs from our own use [Sc. British] of old and new. In the course of the 20th century, however, the tyre became a common British spelling.

History

The first Tyres were leather belts, then iron (then steel), which were mounted on wooden wheels used on carts and wagons. The tyre is heated in hot forging, placed above the wheel and switched off, which leads to metal compression and sits firmly on the wheel. A skilled worker known as a cartographer has done this work.

The first patent for a seemingly standard Tyre appeared in 1847, filed by Scottish inventor Robert William Thomson. However, this was never put into production. The first practical tyre was made in 1888 on May Street, Belfast, Belfast, Belfast by Scottish John Boyd Dunlop, owner of one of the most successful veterinary clinics in Ireland. It was an attempt to avoid the headaches of his 10-year-old son Johnny when he was riding his tricycle on rough roads. His physician John, later Sir John Fagan, prescribed the boy's bicycle rides as an exercise and regularly visited him. Feigan was involved in the development of the first Tyres. Cyclist Willie Hume demonstrated the superiority of Dunlop Tyres in 1889 and won the first Tyre races in Ireland and England. In the description of the Dunlop tyre patent of 31 October 1888, his interest was focused exclusively on the use in bicycles and light vehicles. In September 1890, he was informed of early developments, but the company retained information for itself.

In 1892, Dunlop's patent was invalidated by Robert William Thomson, London, due to the high level of technology (London 1845, France 1846, USA 1847), although Dunlop "recognizes that rubber can withstand Tyre wear and tear while maintaining its strength. John Boyd Dunlop and Harvey du Cross worked together to overcome the significant difficulties this caused. They hired the inventor Charles Kingston Welch, as well as other rights and patents that allowed them to protect their Tyre business to some extent. The Tyre will become a Dunlop Rubber and Dunlop Tyres. The development of this technology has been marked by countless technical advances, including the vulcanization of natural rubber with grey and the development of a "wedge" rim for the side mounting of the tyre to the wheel rim.
Synthetic rubbers were invented in Bayer's laboratories in the 1920s. In 1946, Michelin developed the design of radial tyres. In 1934, Michelin bought a failed carmaker Citroën to immediately apply this new technology. Thanks to its excellent handling and fuel consumption, the technology quickly spread to Europe and Asia. In the United States, the outdated design of dual-layer Tyres continued until Ford Motor Company introduced radial Tyres in the early 1970s, after 1968, when an article in the influential American magazine Consumer Reports highlighted the superiority of radial design. The U.S. Tyre industry lost market share to Japanese and European manufacturers who were buying American companies.
Applications

Facilities can be operated by the type of vehicle they operate. They vary in weight of equipment and applications, for example, in cars, aeroplanes or bicycles.

Automotive
Light-medium duty
Light tyres for passenger cars carry a load of 550 to 1100 kg (250 to 500 kg) per drive wheel. Small trucks and minibuses with a load capacity of 1.1 to 3.3 thousand pounds (500 to 1.5 thousand kg) carried goods on the drive wheel. They differ in the speed of different vehicles, including (from the lowest to the highest): winter tyres, light truck tyres, entry-level tyres, sedans and vans, sports sedans and high-performance cars. The speed of the different cars varies from the lowest to the highest. In addition to road tyres, these special categories also include special categories:

Winter tyres are designed for use on snow and ice. They have a tread pattern with greater free space than summer Tyres, which increases traction on snow and ice. Tyres that have passed a special winter grip test are eligible for the "Three Layer Snowflake Mountain" on the sidewalls. Tyres designed for winter conditions are optimised for temperatures below 7°C (45°F). Some winter tyres have metal or ceramic studs that protrude from the tyre to increase traction in snow or ice in solid containers. The studs carry the liner dry, creating dust and wear on the track. Regulations requiring the use of winter Tyres or allowing the use of nails vary from country to country in Asia and Europe, and from state to state or province to province in North America.

Winter Tyres include Tyres with an M+S degree of protection, which means that they are quieter on clean roads, but less resistant to snow or ice than winter Tyres. These tyres have smaller tread openings than winter tyres and larger than summer tyres.

Off-road Tyres for off-road vehicles are designed to provide sufficient traction when driving off-road, but have good performance and acoustic properties when driving on the road. These tyres are better suited for snow and rain than street tyres and are "good" for ice, stone and sand.

Mud-terrain-Mudder-Terrain Tyres have a deeper, more open tread for better grip in the mud than off-road Tyres, but are less effective on the asphalt.

High speed and high-speed tyres are designed for speeds up to 270 km/h and ultra-fast tyres for speeds up to 299 km/h, but have better handling and durability.
Other types of lightweight car Tyres include mileage Tyres and racing Tyres.
Punctures - Punctures no longer require spare Tyres as they can move more slowly in the event of a puncture, using a stiff sidewall to prevent rim damage. Cars without flat wheels rely on a spare Tyre, which can be a compact Tyre, to replace the damaged Tyre.

Competition Tyres - Competition Tyres are divided into three main categories: DOT (legal street Tyres), non-slip Tyres and rain Tyres. Race Tyres are designed to maximize cornering friction and acceleration at the expense of durability. Race points do not have a tread for maximum contact with the surface and rain tyres have water drains to prevent hydroplaning.

Heavy duty
Heavy truck and bus tyres are available in a variety of profiles and support weights ranging from 1800 to 2500 kg per drive wheel. They are usually mounted in tandem on the drive axle.

Truck Tyres - Truck tyres are available in a variety of profiles, including "low profile" tyres with tread heights ranging from 70 to 45% of the tread width, "large format" truck tyres and "overspin" tyres with the same total contact pressure as dual tyres.

Off-road tyres are used in construction, agriculture, forestry and other soft soil applications. This category also includes equipment that moves on hard surfaces in industrial plants, ports and airports. Tyres designed for soft surfaces have a wide, deep tread that provides traction on dirt, dirt, sand or gravel.

Other
Airplanes, bicycles and various industrial applications have different design requirements.

Aircraft tyres - Most aircraft tyres are designed to land on asphalt surfaces and absorb shock loads to the landing gear via the landing gear. To save weight and space, they are generally small relative to the vehicle they carry. Most of them have a radial layer structure. They are designed to withstand peak loads when the aircraft is stationary, with side loads during landing being an important factor. Although aquaplaning is a problem for aircraft Tyres, they usually have radial grooves and no side grooves or dimensions. Some light aircraft use large diameter, low-pressure tundra tyres to land on unprepared surfaces in desert areas.

Bike tyres can be designed for use on uneven roads or off-road and can be mounted on vehicles with more than two wheels. There are three main types: Clinker, wire and pipe. Most bicycle tyres are equipped with clinker and a rim that is pressed against the rim of the wheel. The inner tube provides air pressure and contact pressure between the side and the rim of the wheel.

Industrial tyres are carried by vehicles such as forklift trucks, tractors, excavators, road rollers and wheel loaders. Those used on smooth surfaces have a smooth floor, while those used on soft surfaces usually have excellent floor textures. Some industrial tyres are solid or filled with foam.

Motorcycle tyres grip the road, resist wear, absorbing surface irregularities and allow the motorcycle to turn backwards. The contact between the two tyres and the ground affects safety, braking, fuel consumption, noise and ride comfort.
