How to solve the low tire pressure when the car prompts?

Find a garage or shop to pump up your tires.

Tyre. Introduction:

Tires are ring-shaped elastic rubber products that are grounded and rolled on various vehicles or machinery. In 1845, R. W. Thomson, a Scottish-born civil engineer, invented the pneumatic tyre, and obtained a patent for the British ** with the title of "Improvement of the Wheels of Horse-drawn Carriages and Other Vehicles". On December 10 of the same year, the first pneumatic tire was born.

Tires are usually mounted on metal rims, which can support the body, cushion external shocks, achieve contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions, and they bear various deformations, loads, forces, and high and low temperatures when driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, high abrasion resistance and flexural resistance, as well as low rolling resistance and heat generation are required.

Half of the world's rubber consumption is used in tire production, which shows that the ability of tires to consume rubber is not insignificant.

Function introduction: Tire is one of the most important components of the car, its main functions are: to support the full weight of the vehicle, to bear the load of the car; Transmit the torque of traction and braking to ensure the adhesion between the wheels and the road surface; Reduce and absorb the vibration and impact force of the car when driving, prevent the auto parts from being subjected to severe vibration and early damage, adapt to the high-speed performance of the vehicle and reduce the noise during driving, and ensure the safety, handling stability, comfort and energy-saving economy of driving.

Composition: Tires are usually composed of three parts: outer tire, inner tube and cushion belt. There are also those that do not need an inner tube, and the inner layer of the carcass has a rubber layer with good air tightness, and it needs to be equipped with special rims.

The structure of tires in all countries of the world is developing in the direction of tubeless, radial structure, flattening (the ratio of tire section height to width is small) and lightweight.

Tire pressure will be affected by temperature, so the general cold car ** pressure, tire pressure range between, the tire pressure of the general model car series is not the same, my front tire and rear tire, this is marked by the manufacturer, so it can not be generalized ** pressure, or combined with their own car, this time to look at their own instructions or take a look.

There are many reasons why a tire pressure is too low, including a broken car tire or a slow car tire leak. When the tire pressure of the car tire is too low, it will affect the handling of the car and will also increase the fuel consumption of the car, so it is necessary to check or supplement the tire pressure in time.

It may be a low tire pressure caused by a punctured tire that causes a flat air leak, or a false alarm from the tire pressure monitor. When the tire pressure is found to be too low, it must be dealt with in time to prevent potential safety hazards.

The low tire pressure is due to the slow deflation of the tire;

There is a leak in the tire; Or a false alarm from the tire pressure monitor.

Now our vehicles have the function of tire pressure detection, if the air pressure is abnormal, it needs to be replenished in time. If the tire pressure of a car is normal but the display is not normal, you should ask the staff of the 4S shop to eliminate the fault for you**.

1.The causes of low tire pressure are: low temperature; flat tires; Or the tires, rims and hub equipment are ominously destroyed and sold in place.

2.Tire pressure refers to the pressure of the air inside the tire, which plays an important role in the performance and power of the car.

3.The hazards of tire pressure are: the coefficient of friction with the road surface will increase; The steering wheel is heavy and easy to fall off, which is not conducive to driving safety; Increase the amount of tire movement, resulting in abnormal tire irritation; Thus reducing the action of rope and rubber; The friction between the tire and the ground increases, the tire temperature rises sharply, and the tire becomes softer; It will increase the deformation of the carcass and make it easy to crack the sidewall.

Promote the aging of rubber and accelerate shoulder wear.

Tire pressure monitoring shows that low tire pressure is due to tire leakage, tire debris sticking to the tire pressure sensor, or the tire pressure monitoring sensor is not sensitive.

Tire pressure monitoring system is abbreviated as "TPMS", which is the abbreviation of "Tire Pre SS Ure Monitoring System". This technology can automatically monitor various conditions of tires in real time by recording tire speed or electronic sensors installed in tires, which can provide effective safety for driving. There are two types of tire pressure monitoring systems:

One is the indirect tire pressure monitoring system, which judges whether the tire is abnormal by the speed difference of the tire; The other is the direct tire pressure monitoring system, through the installation of four tire pressure monitoring sensor socks in the tire, in the car stationary or driving process of the tire pressure and temperature of real-time automatic monitoring, and the tire high pressure, low pressure, high temperature timely alarm, to avoid traffic accidents caused by tire failure, to ensure driving safety.

It is recommended to check the tire pressure regularly, the tire pressure is an important factor affecting the life of the tire, not too high or too low, and inflate according to the tire pressure indicated by the vehicle. Try to keep the tire pressure low in the summer; In the cold winter, try to ensure that the tire gas of the car Lu Juyan is more than that in summer, because the tire is easy to expand and contract.

The specific solutions to low tire pressure are as follows:

1.If the tire pressure of the car is too low, if the car leak is not very serious, the vehicle can be supported to drive to the nearest tire repair shop for treatment.

2.If you have a car pump, you can inflate the tires first, and then drive slowly to the repair shop.

3.The air leak makes the stool very serious, and it is recommended to replace the spare tire to avoid deformation of the wheel hub due to continued driving.

Here are the precautions when inflating tires:

1.Pay attention to safety when inflating, and check the air pressure with a barometer at any time, so as not to burst the tires due to over-inflation of the car.

2.Check the valve, if the valve and the valve core are uneven, there is a convex and concave phenomenon and other defects, it is inconvenient to inflate and measure the air pressure.

3.The air inflated should be clean, and the air filled into the sail should not contain moisture and oil to prevent the inner tube rubber from deteriorating and damage.

This condition can be caused by not driving for a long time, or it can be caused by a tire that is slow to flat. If the air pressure is insufficient, it needs to be inflated immediately. Don't let the tires work at low air pressure, otherwise it will affect the handling of the car and the life of the tires.

Air pressure is very important for tires. If the air pressure is too high, the contact area between the tire and the ground will become smaller, resulting in a decrease in tire grip.

The reduced grip can affect the driving stability and handling of the car.

If the air pressure is too low, it will cause the tire to deform at high speeds, accelerate the tire aging rate, and increase the probability of puncture.

If the tire pressure is not suitable, it needs to be adjusted immediately.

Tires are rubber products, and rubber products will age after long-term use, so tires need to be replaced regularly.

When buying new tires, be sure to look at the production date, as tires have a shelf life.

Don't buy it when it's expired.

After installing the new tires, be sure to re-check the dynamic balance of each wheel to prevent abnormal wheel shaking at high speeds.

If the wheels shake abnormally at high speeds, it will affect the car's handling and driving stability.
