Car tire: It is also known as car tire and car tire.
and it is the only part of the car that is in contact with the ground. in contact with the ground; Asphalt, sand, gravel, dirt, mud, etc. are in contact with the tires. Therefore, their resistance against these materials is of great importance.
What is a car tire?
Tires themselves are divided into two general types, "pneumatic and non-pneumatic". Pneumatic tires consist of two general groups: tubeless (bias) and tubeless (radial).
In the non-pneumatic type, it can be divided into two groups: "SOLID" tires, which are usually used in industrial machines, and "Polyurethane" tires, which were recently invented.
The external structure of the tire consists of the tread (top), manjid (carcass), body (wall), collar (willow) and the ingredients of the tire are: types of rubber, carbon black, thread, wire, oil, sulfur, Accelerators, protectors, etc.
Knowledge of car tires and their use
The ability to carry load, transfer torque, drive, brake and absorb shocks to the wheel for the comfort of the passenger is one of the main uses of car tires, and at the same time, it should have good steering, shape stability, less fuel consumption, vibration and low noise. have
Other functions of this sensitive part include high durability and safety, the ability to withstand heat up to 60 degrees.
1. The old car tire
The tires of the seventies were known as cotton tires. Because the top cover of these tires was made of silk threads.
And even today, many elderly people still emphasize the efficiency and quality of these tires. However, the progress of science and technology caused wire tires to replace cotton tires.
2. The wire tires of the car
New generation tires are known as wire or radial tires. Of course, these tires were produced since the late 70s.
Radial tires have a cross section covered with steel cross wires, which increases pressure tolerance and speed at high speeds.
Also, show better performance than the previous tires (thread).
