Concept in Definition ABC

The tire It is a piece of toroidal shape, and made from rubber, which It is available on the wheels of various vehicles and machinery such as: cars, trucks, planes, bicycles, motorcycles, industrial machinery, forklifts and cranes, among others.
Thanks to the tire, the vehicle or device in question adheres to the pavement allowing them to start and stop.

In addition, the tires have threads that reinforce their texture, while, by the direction they hold, we can classify them as: radial, which are the ones used for cars today, meanwhile, the layers of material are placed on top of each other in a straight line. This gives the deck greater stability and resistance; the diagonals, the layers are placed exactly diagonally one above the other; and in the self-supporting the layers are also on top of each other in a straight direction and also on the flanks. This provides resistance to the cover although it reduces in terms of comfort since it makes it more rigid. The most usual is his app in sports cars.

A physical characteristic of tires is that their dimension is inscribed on them, for example, if the following is inscribed legend 225 / 50R16 91W, this will read as follows: the first number corresponds to the sectional width from the edge of a band the other; the second number implies the height of the profile; the R accounts for its radial type; the next number is the measure of the circumference inside; the fourth number indicates the load to be given to the tire; and the final letter will imply the velocity that you can achieve. In the code the W refers to a speed up to 270 Km / H.

It should be noted that it is also often called tire or rim.

Towards the end of the 19th century, in the year 1888, the Scottish inventor John Boyd Dunlop created the first inner tube tire. air for your little son's tricycle who used that means of locomotion to go to the school and had to face the very bumpy streets of Belfast. The advent of the tire facilitated a much smoother ride than that previously proposed by solid rubber tires.
Without a doubt, the creation of Dunlop came at the most opportune moment given that at that time the transport Terrestrial was in full expansion and of course, it was like a glove.
