Why does the car have an inner tube? Many people do not know why?

Many people know that car tires do not have inner tubes, but why not, but they do not know, even the master in the 4S shop can not tell why the car does not have inner tubes, then the problem arises, why, car designers What kind of consideration did not add inner tubes to car tires? There are also car owners who don't know what specifications and year the tires on their cars are. Here's how to teach you about cars.

 

 

Let's first understand how the current car tires are composed, and there are several types, years and specifications.

automobile tire composition

1. Lining layer: a layer of airtight synthetic rubber (equivalent to inner tube).

2. Carcass ply: This layer is above the inner liner and consists of thin fiber cords bonded with rubber.

3. Low bead area: This is the position where the rubber tire clamps the metal rim.

4. Bead: The bead is firmly fixed on the rim to ensure air tightness, and the tire is correctly installed on the rim

5. Tire side: It can protect the side of the tire from the impact of the curb and the road surface

6, carcass layer: it largely determines the strength of the tire.

7. Crown ply (or "zero degree" belt): This important safety layer can reduce frictional heat and help maintain the shape of the tire when the vehicle is driving fast

8. Cap (I. e. belt): provides a hard base for the tread.

9. Tread: Provide traction and turning grip for tires, and adopt anti-wear, anti-friction and high temperature resistance design.

 

 

There are several types of car tires.

According to the inflation pressure, it is divided into: high-pressure tires. Low pressure tires. According to the tread pattern is divided into: ordinary pattern tires. Off-road tread tires. Mixed tread tires. According to the carcass structure is divided into: ordinary structure tires,. Radial structure tires (most common in automobiles). Divided into passenger tires and truck tires by purpose

 

 

How to look at the tire year and specifications, please see the figure below!

 

 

The figure is (3907) year to read 07 (year) 39 (week), so the production date is the 39th week of 2007, that is, late September 2007.

 

 

Designers out of what kind of consideration?

The traditional tire structure of inner and outer tires is less used on cars. As the name implies, there is an inner tube filled with compressed air in the outer tire. His disadvantage is that the driving temperature is high, it is not suitable for high-speed driving, and the safety is poor. When in use, the inner tube is in a stretched state in the tire, and a small hole is formed after a slight puncture, which makes the tire quickly depressurize.

 

 

Tubeless tires do not use an inner tube, and air is directly filled into the inner cavity of the outer tire. In this way, the friction between the inner and outer tires is eliminated, and the heat is directly dissipated from the rim, which is more than 20% lower than that of ordinary tires. Tubeless tire is a kind of improved outer tire, which plays the dual role of ordinary outer tire and inner tire at the same time. Tubeless tires are safer than inner tubes, vacuum tires are more wear-resistant, vacuum tires are more fuel-efficient, and vacuum tires are stable, especially radial tires, with zero crown angle and strong adhesion.
