Understand the structure of tires it's not as simple as you think
- Jul 26, 2017 -

The tyre is the only part of the vehicle that touches the road. Tyres must be balanced between traction, comfort, durability, energy efficiency and total cost. To meet these conflicting needs at the same time, the design and manufacture of tires may be more complex than you might think.
1. Inner liner: A layer of airtight synthetic rubber (equivalent to inner tube).
2. Carcass cord layer: The layer is above the inner liner layer and consists of a thin fiber cord bonded with rubber. These cords largely determine the strength of the tyres and help to withstand the pressure. The standard tyre contains about 1,400 cords, each of which can withstand 15 kg of gravity.
3. Low tread area: This is the position of the rubber tyre clamping metal rims. The engine and braking power are transmitted from the rim to the contact area of the road.
4. tire ring: The bead is firmly fixed on the rim to ensure the tightness, and the tyre is properly mounted on the rim. Each wire can withstand a load of 1,800 kg without breaking. The car has eight tyres, two tires per tire. With a large compressive strength of 14,400 kg. A ordinary cars weigh about 1,500 kilograms.
5. Tire Edge: Can protect the tire side, so that it is free from the road edge and road impact. The tire side contains important details of the tyre, such as the tyre width and speed level.
6. Carcass skeleton layer: It determines the strength of the tyre to a large extent. It is made of a very fine steel cord that is bonded with rubber. This means that the tyres can withstand the cornering stress and will not swell because of the rotation of the tyres. It is also resilient enough to eliminate deformations caused by collisions, pits and other obstructions on the road.
7. ply layer (or "zero" band Layer): This important safety layer can reduce the friction heat, help to maintain the shape of the tire when the vehicle is running fast. To prevent the centrifugal stretching of the tyre, the reinforced nylon cord is embedded in the rubber layer and laid along the tire circumference.
8. Ply (i.e. with bundle layer): Provide hard base for tread.
9. tread: to provide traction and cornering force for tires, the use of anti-wear, anti-friction and high temperature design.
Besides the effect of tyre structure on tyre performance, tyre structure has a certain effect on the performance of the tire body. This shows that there is a great connection between tyre structure and tyre performance.
