The invention of the tire.

 Robert Thomson invented and patented the pneumatic tire in 1845. His first project used a significant amount of light air-filled tubes inside a leather tires.
This project was more appreciated than the later projects because of one inner tube puncture did not cause the air across the mouth of the tire, and by changing the pressure it was possible to change the driving conditions.Unfortunately, this invention had no luck from the moment began the endless problems with assembly and production of these tires. This idea has been revived on the occasion when a veterinary surgeon noticed that the tires will be perfectly served his three-wheeled bike in 10-year-old son: he produced a pneumatic tire tread.Relative success in this regard encouraged the surgeon, John Dunlop to advertise their tires in The Irish Cyclist, in December 1888. In May the following year a new tire was experiencing its heyday.At Belfast Cycle Race has been charged to victory thanks to a pneumatic rubber tires, since the public interest in these tires. Unfortunately the original tire also had its drawbacks. It was difficult to access because the tire inner tube was attached to the wheel. In 1890, CK Welsh patented the design rim and its outer covering of internal performance nierozciągliwym wheel rim. This invention heralded the advent of modern tires. For many years he has developed a tire up to the present shape. For two of the most important technical development processes are the development of radial tires by Michelin in 1948: this project contributed to a better adhesion to the substrate of the vehicle and traction.Previous structure consisting of contact between the layers diagonally, and running transversely kordach, proved to be very stable structure, but the walls of the tires were too hard and impossible to navigate the flexible substrate particularly during maneuvering.Michelin rubber producing their cords arranged in a radial manner of giving the cushioning of the tire, better control of the vehicle with flexible walls of the tire, which resulted in improving traction and handling and braking.At that time the pneumatic tire was produced with the tube: a new project was introduced during the 20's, when the tube was removed from the tire, but tire technology was not advanced enough and was not accepted in the tire industry.This was achieved in 1972, when the inner tube with disabled Dunlop tires and tubeless tires produced, which became the 'norm' among tire manufacturers. Tubes, however, are still used to solve the problem of puncturing the tires, when it is expected that the tire was safe on the road.For many years, research and development, dictated by the needs of different markets, meant that automotive tires can meet different needs. The scale was enormous applications, from Formula 1 competition type vehicles for use as large as buildings.All tires affect the ride comfortable, substantial resistance to penetration and to achieve. Many of the names we associate with, such as tires - Goodyear, Dunlop, Michelin, and Bridgestone Mirella - to name just a few of them - have contributed to the success of modern automobile tires. These companies, as well as other work on the rock world: production center is located in China and India but also in other European countries and the United States. However, for sure Dunlop will always be associated with a tubeless pneumatic radial tire, the legacy remains the measure of the inch (inch), which is now used globally to measure the diameter of the circle.Conversion to metric measurements not applicable technical parameters - all wheel sizes are 13,14,15,16,17,18 and 19 for ordinary cars, for example - 'code' that relates the diameter wheels ... 13 ", etc.The reasons for this, that the cost of the tires seems to be quite high compared to other parts of the service, it is important that vehicle owners bought the right size tires for their vehicles - in accordance with such technical parameters that ensure road safety and acceptance authorities ITV. Another problem, which we will try to explain the coding is different tire sizes, as well as consultation on solving problems when mounted tires are not in accordance with the official documentation of the vehicle.
