What are radial and wire tires and why do so few people buy them?

The journey of a thousand miles begins with a single step. For trucks, tires are its shoes, to run up to save oil, it is necessary to choose the right tires.

Today, I will tell you what is the difference between the several types of tires.

Radial tires VS bias tires

Nowadays, radial tires are generally divided into all-steel or semi-steel, to distinguish between these two different, we can not help but talk about the structure of radial tires.

The world's first radial tire was invented by the French Michelin company in 1946, because the direction of its carcass cord arrangement like the earth meridian, to the center of the wheel axle, from a bead to another bead, radial arrangement. Therefore, this tire is called radial tire.

The radial tire is relative to the bias tire, and the traditional bias tire is different, although the cords of the belt bundle layer is diagonal cross arrangement, but with the center line of the tire crown was a very small angle, the carcass cords are arranged according to the meridian direction of the center line of the inner tire crown was 90 °; and there are cords are arranged almost close to the direction of the circumference of the belt bundle layer bundle tight carcass.

Semi-steel refers to the tread part of the steel wire as a reinforcing layer, the carcass is made of nylon or polyester material; all-steel, in addition to the tread, the carcass is also all steel wire to bear the force.

Belt ply are used steel cord, generally used for heavy and construction machinery vehicles, semi-steel radial tires steel radial tire carcass using rayon or other fibers, the belt ply with steel cord, this type of radial tires are generally used for cars or light trucks, such as buses, etc..

The biggest difference between these two types of tires is the way the cord ply material is arranged in the middle of the tire.

Radial tires vs. bias tires

Radial tires have the ply material arranged vertically across the tire like a radial, while bias tires have the ply material arranged at an angle of about 45°, which can be seen in the comparison of the two types of tires in the chart above.

Compared with bias tires, radial tires have the following advantages:

1. long service life;

2. low rolling resistance, saving fuel;

3. large load capacity; good adhesion performance;

4. low tire temperature, fast heat dissipation;

5. tread is not easy to puncture, not easy to blow out the tire.

Because of the obvious advantages of radial tires, the application of bias tires has been very little.
