What's the use of car tyres?
Long before the tire is made of wood, iron and other materials, the first hollow wheel is in 1845 the British Robert Thomson invention, he put forward the flexible bag filled with compressed air, to ease the movement of vibration and shock. Although the tyres were made of leather and coated canvas, the tyres had shown the advantages of small rolling resistance. According to this principle, in 1888 John Dunlop made of hollow rubber tires, Thomas then made a hollow rubber tire is provided with a valve switch, but because there is no inner canvas, and can not maintain a certain cross sectional shape and section width.
Tire is one of the important parts of the car, it is directly in contact with the road, and vehicle suspension work together to ease the impact of the vehicle, to ensure a good car ride comfort and ride comfort; ensure that the wheels and pavement have good adhesion, improve vehicle traction and braking and by; bear the weight of the car, the important role played in the car tire has been paid more and more attention.
In 1895, with the advent of the automobile, the development of pneumatic tires widely, the first tire sample is 1895 appeared in France, this is the single type tire made of plain canvas, although there is no pattern tread. Until 1908 to 1912, the tires have changed dramatically, the tread has increased the performance of the pattern, so as to exploit the tread pattern of history, and to increase the section width of the tire, allowing the use of low pressure, in order to guarantee good cushioning properties.
