How many layers are the tires of the car?
The meridian is the tyre technique. Almost all tyres are now using this technology or higher than this technology. What you say is that the car tires are generally divided into three layers. In addition to what you said, there is a coat of outer rubber. You can see the picture below.
It depends on what kind of tyre you are. I've seen tyres up to 18 stories, but that's truck. Cars are generally made of nylon. This is not the level of the group.
Radial tire (Radial tire) is a combination of two or three layers of steel wire rings placed on the cord fabric carcass. The carcass cord is connected from one side bead to the other. The bead is much like the meridian of the earth, so the structure of the tire is called a radial tire.
