Different tires are used in machines according to working conditions. In light vehicles, the tires are often the same; But in heavy machinery and vehicles, different tires should be chosen according to the variability of the work.
Rubber Building
1- Layer (belt):
A layer is placed inside the body of the tire, which is reinforced with wire (radial) or nylon (thread) layers. . As mentioned in the introduction, the rubber should be selected according to the working conditions, and not paying attention to this issue and choosing the wrong type of wire or thread type of rubber will lead to a lot of financial losses for the organization.
2 - Tire body (carcass):
The tire body takes the impacts and loads on the tire and is made of special layers of string and cross materials that are They are sufficiently resistant to internal pressure. This part forms the skeleton of the rubber.
3- Liner or inner wall:
This layer has a completely smooth surface, which is responsible for maintaining the inner air of the tire in tubeless tires. In tube tires, the tube is placed inside. The inner wall is made of anti-corrosion fibers and resistant to cold and heat so that it can provide a suitable and safe container for the rubber.
4- Metal threads (bead wire):
Metal threads are made of copper or steel wires and are responsible for maintaining the tire collar to keep the tire in the rim. Hold tight. Metal threads help tubeless tires to prevent air from entering and exiting and keep the tire and rim in shape. If this part is damaged and torn, it is not possible to restore and repair the tire. Therefore, when replacing and installing on the rim, care should be taken so that this part is not damaged.
5 - Fragile (chafer):
This part is placed between the tread and the layers, which takes the shock to the tire and prevents sharp objects from sinking into the tire. 6- Side wall: The wall or side protects the tire body and layers during The movement of the tire constantly inflates in and out.
7- Tire heel (tread):
The tire heel is the outermost layer of rubber, which prevents the wear of the inner parts of the tire and reduces the impacts to the minimum possible amount. . The part of the tire heel that is in contact with the ground is called the tread, which is made of different materials and in different shapes depending on the working conditions. That is, the shape and size of the tire tread or crown depends on the tire models in terms of traction, cutting, heat resistance, and a larger cross-sectional area.
