What do car tires, radial tires, wire tires, and bias tires refer to and what are the differences

Bias tires are also known as ordinary structural tires. Refers to the pneumatic tire in which the adjacent layers of the carcass cord and the buffer layer are crossed and arranged at an angle of less than 90 angles with the tread centerline. This type of tire has good longitudinal rigidity and is suitable for medium-speed driving on ordinary road surfaces.

Radial tires are a structural form of tires, which are different from bias tires, arch tires, pressure regulating tires, etc.! Commonly known as "steel wire tires". The cord arrangement of the radial tire carcass is different from the bias tire, the cord of the radial tire is not crossed with each other, but is close to parallel to the outer tire section, like the earth meridian arrangement, the cord angle is small, generally 0 °, there is no maintenance intersection between the carcass cord, when the tire is in the process of driving, the stress around the crown increases, which will cause circumferential stretching, and the carcass becomes a radial crack.

Therefore, the buffer layer of radial tires adopts a close circumferential arrangement of the cord layer, which intersects with the angle of the carcass cord at 90 °, generally 70 ° to 78 °, forming a rigid annular belt that can hardly be stretched, fixing the whole tire, limiting the circumferential deformation of the tire, and this buffer layer bears 60% to 70% of the internal stress of the whole tire, becoming the main stress component of the radial tire, so it is called the belt layer of the radial tire. The main stressed part of the bias tire is not on the buffer layer, and 80% to 90% of its internal stress is borne by the cord layer of the carcass. It can be seen that the design of the radial tire belt layer is very important, it must have good rigidity, and multi-layer fiber materials with large angles, high strength and not easy to stretch, such as steel wire or glass fiber, can be used.

It refers to the way the cord is arranged in the inner ply of the tire!

The fundamental difference between a radial tire and a bias tire is the cord arrangement structure of the tire carcass, which is also named.

2. The former carcass cord arrangement is at an angle of 90 or close to 90 degrees with the rolling direction, and the carcass is covered with cord cloth.

3. The carcass cord of the latter is cross-arranged, and the carcass has multiple layers of cord.

4. Radial tires have advantages over bias sensitive leakage tires: less heat generation, less deformation, fuel saving, load resistance, etc., which are used for passenger car and truck and bus tires.

5. The advantages of bridge rotten bias tires are mainly reflected in short-distance low-speed puncture resistance and low cost, and are mostly used for agricultural tires and engineering tires.

6. Tire development trend: radial, flattened, tubeless.

7. The advantage of radial tires over bias determines the wide use of radial tires.

The difference between ordinary bias tires and radial tires is that the cord arrangement of the radial tire carcass is different from that of bias tires. Radial tires have a thicker crown, good wear resistance, and have the advantage of low rolling resistance; Whereas, bias tires last longer. Information on bias tires and radial wheel lift tires is as follows:

1. Bias tire is an old-fashioned structure of tire, which refers to the pneumatic tire in which the cord layer and the adjacent layer of the buffer layer are crossed and arranged at an angle of less than 90 degrees with the tread centerline. 2. The cord arrangement of the radial tire carcass is different, including the slag in the bias tire, and its cord is not the type of intersecting and intersecting, but is close to parallel to the outer tire section, like the earth's meridian arrangement, and the cord angle is generally 0 degrees.

The differences between radial tires and bias tires are: 1. Different materials: radial tires are wire tires; Bias tires are nylon tires.

2. The cord is different: the cord arrangement of the radial tire carcass is close to parallel to the outer tire section; The ply layer and the cushioning layer of the bias tire are crossed by adjacent cords. 3. The carcass is different

The carcass cord of radial tires is wound side by side, and the top layer of the carcass contains a layer of steel strip made of steel wire; The carcass of a bias tire is a ply layer with a slash crossing. The functions of tires are: 1. Support the full weight of the vehicle and bear the load of the car; 2. Transmit the torque of traction and braking to ensure the adhesion between the wheels and the road surface; 3. Reduce and absorb the vibration and impact force of the car when driving, and prevent the auto parts from being subjected to severe vibration and early damage; 4. Adapt to the high-speed performance of the vehicle and reduce the noise during driving, so as to ensure the safety, handling stability, comfort and energy-saving economy of driving.

1 The fundamental difference between radial tires and bias tires is the carcass. The carcass is the foundation of the tire, which is a layer-by-layer structure made up of cords. The carcass of a bias tire is a ply layer with a slash crossing. The carcass cord of radial tires is wound side by side, and the top layer of the carcass often contains a layer of steel strip made of steel wire.

2. In terms of design, bias tires have many limitations, such as the strong friction of the crossed cords, which makes the carcass easy to generate heat, so it accelerates the wear of the tread, and its cord layout cannot provide excellent handling and comfort; The steel ribbon in the radial tire has better flexibility to adapt to the irregular impact of the road surface, and is durable, and its cord structure also means that there is much less friction than the diagonal line when the car is driving, so as to obtain a longer tread service life and better fuel economy.

3 The radial tires themselves have characteristics that make it possible for tires to be tubeless. Tubeless tires have the well-established advantage of not bursting like a bias tire with an inner tube (which is very dangerous) when the tire is punctured, but allows the tire to maintain air pressure for a period of time, improving the driving safety of the car.

4 Radial tires have better grip. Due to the special carcass structure of radial tires, the car has a strong grip and good effect while driving. Therefore, the choice of mid-line tires for the same model of car has better handling and comfort than bias tires.

Because radial tires have the above advantages compared to bias tires, the vast majority of cars today choose radial tires.

a, the cord cord arrangement direction is consistent with the radial section of the tire, b, and has a number of layers of cord and the radial section at a large angle, high strength, not easy to stretch the circumferential ring similar to the buffer layer of the belt.

Advantages and disadvantages: large grounding area, good adhesion performance, small rolling resistance; It is not easy to puncture, the driving deformation is small, and the fuel consumption is reduced; Good heat dissipation; The load capacity is large; good driving stability; Prone to cracks; noisy; high cost;

Answer: Radial tires are a structural form of tires, and the international code is "R", commonly known as steel wire tires. The angle formed between the steel wire tie cord and the carcass cord of the tire is like the radial cord of the earth, so the tire is called "radial tire". This kind of tire is characterized by good wear resistance and puncture resistance, and long service life; Low rolling resistance and low fuel consumption; Large bearing capacity; Good shock absorption.

1. Good wear resistance and puncture resistance. The radial elasticity of the radial tire body is large, which increases the ground contact area of the tire and decreases the pressure, so its tread has strong wear resistance and puncture resistance, and the mileage is about 30% more than that of ordinary slash tires;

2. Low rolling resistance, saving fuel consumption. Due to the small number of radial tire cord layers, low driving temperature, fast heat dissipation, and small circumferential deformation, the rolling resistance is small, which can improve fuel economy and save fuel consumption;

3. Large carrying capacity. The cord arrangement of radial tires is consistent with the main deformation direction of tires, so the strength of the cord can be fully and effectively utilized, so the bearing capacity of radial tires is more than 10% higher than that of ordinary slash tires.

4. Good shock absorption performance. The radial elasticity of the radial carcass is large, so the radial deformation is large, which can alleviate the impact of uneven road surfaces and improve ride comfort.
