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: automobiles, 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 starting and braking thereof.
In addition, the tires have threads that reinforce their texture, while, due to the direction they have, we can classify them into: radial, which are the ones used for cars today, meanwhile, the layers of material are laid one on top of the other in a straight line. This gives the cover 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 comfort as it makes it more rigid. The most common is its application in sports cars.
A physical characteristic of the tires is that their dimension is inscribed on them, for example, if the following legend 225/50R16 91W appears, this will be read as follows: the first number corresponds to the sectional width from the edge of a band to the other; the second number implies the height of the profile; the R accounts for its radial type; the next number is the measurement of the inner circumference; the fourth number indicates the load that must be given to the tire; and the final letter will imply the speed it can reach. 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 1888, the Scottish-born inventor John Boyd Dunlop created the first inner tube tire for his young son’s tricycle. that he used this means of locomotion to go to school and had to face the very bumpy streets of Belfast. The advent of the tire facilitated a much smoother ride than that proposed until then by solid rubber tires.
Undoubtedly, the creation of Dunlop came at the most opportune moment since at that time land transport was in full expansion and of course, it came like a glove.
