Buying new tires for a car can become one of the most stressful and complicated decisions for owners, especially inexperienced ones. Most people simply underestimate the importance and position of tires, but the truth is that tire production has become a sensitive, complex, vital and profitable industry. Car tires are like shoes for human feet, so choosing the right tire will provide better comfort and performance.
Car tire structure
A car tire is composed of various components, the existence of each of which is vital for its correct and safe operation. Tires have a layered structure that is well displayed in the image below.
Collar The collar is a ring made of several high-strength steel strands covered with rubber. The main task of the collar is to position and center the tire and the rim, as well as absorb the forces from the rim to the tire.
Body The tire body is made up of several layers. The most common layer used is polyester threads. In radial tires, these threads are placed perpendicular to the tire tread. In older tires, the threads were placed at a certain angle to the tread. Finally, the woven layers are covered with rubber so that in addition to bonding with other layers, they can trap air inside the tire. Sometimes the strength of tires is measured by the number of layers of their body. In most cars, two-layer tires are used, but in the tires of large commercial airplanes, the number of layers reaches 30 and more.
belt Belts are a layer of steel threads that are placed just below the tire tread. The duty of the belts is to strengthen the strength of the tire against the puncture, as well as to maintain a smooth and suitable surface when the tire contacts the road surface.
Additional layers of polyester Some tires have one or two extra layers of polyester, which makes the other layers stick together with more strength. These extra layers are mostly seen in high speed tires.
Side wall The side wall in the tire is responsible for maintaining the lateral strength. This part is vital for taking care of other layers as well as protecting the side of the tires and maintaining the air inside the tire.
tread Tire tread is a combination of several natural and synthetic rubbers. The tread and the side wall are produced by extrusion method, and at this stage, the rubber surface is produced without the usual patterns on the tread to create friction.
