What is the reason for the please check the tire pressure displayed on the car?

One is that there are small nails piercing the tire in the blind spot, and the other is that the tire valve is not tightened properly.

1. The pattern is worn badly.

An inexplicable puncture indicates that there is something wrong with the tire itself. Checking the pattern of tires may be the most intuitive way to judge the quality of tires. As the friction time becomes longer, the depth of the pattern will also become much less with the change of friction, when the depth of the pattern reaches 3mm, then this may be a reminder that it is time to change the tire, don't ignore it.

2. The tire pressure is abnormal.

A full-featured car will have a tire pressure monitoring function, and many traffic accidents are caused by abnormal tire pressure. The tire pressure is high, and the brakes are not easy to control; If the tire pressure is low, the car will not have enough power. It is still necessary to check the tire pressure before driving.

Tire pressure alarm, indicating that one or more tires are under- or over-pressurized.

Tire underpressure and overpressure will lead to abnormal tire wear, shorten tire life, increase fuel consumption and even increase the chance of puncture. Tire experts recommend that we check the tire pressure once a month to ensure that the tire pressure is normal.

The tyre pressure check must be done while the tyre is cool. Tire pressure can be checked using a tire pressure gauge or a tire pressure monitoring system (TPMS). The vehicle instructions will list the standard tire pressures for the vehicle under various load conditions.

At the same time, this parameter is also listed on the label next to the driver's door.

The standard tire pressure of a tyre is about too high a tire pressure that can increase tire wear and tear and may cause a puncture, while too low a tyre pressure can increase fuel consumption and the bumpiness of the vehicle. Generally speaking, the tire pressure can be slightly lower in summer and slightly higher in winter.

The reason for the please check the tire pressure displayed on the car is that the tire pressure is not enough.

Get out of the car and see if the 4 tires are flat, if they are all good, you can drive. Then go to the tire shop and check the tires for nail leaks. If the tire pressure is adjusted after the air leak is repaired, then the tire pressure on the meter is reset.

A tire pressure gauge or tire pressure gauge is a special pressure gauge that is used to measure the pressure in the tires of cars, trucks, bicycles, etc. The tire pressure gauge uses pressure sensing technology to achieve high measurement accuracy (less than the error and long service life.

Using a tire pressure gauge to test the tire pressure in time can enable motorists to know the tire pressure of their car tires in time. The pointer type is easy to operate, the digital reading is convenient, and the alarm type does not display the tire pressure value. Each tire pressure gauge has a certain pressure measurement range, generally household only 0-100psi, no need for trucks and other heavy-duty tire pressure gauges, ** from 12 yuan to 100 yuan.

If the vehicle has a hint of tire pressure problem to check the tire, it is best to stop and check whether the tire of the vehicle is punctured by a foreign object causing the tire to leak, etc., and troubleshoot the fault in time.

Car display check tire pressure treatment method:

First of all, check whether the lower tire pressure is normal, and check whether the air pressure of the tire is too high or too low. If it has been charged to the standard value and still prompts, you need to calibrate the tire pressure, the calibration method can be checked in the car manual, or go to the repair shop to use the diagnostic instrument calibration.

The standard air pressure for standard tires is indicated on the driver's side of the door or on the side of the door (this standard value can also be found on the fuel tank cap and on the instruction manual). It should be noted that there are different standard units for the expression of air pressure, generally there are 3 or 4 types.

Just as the weight is expressed in kilograms, there are also 3 4 units on the barometer, such as kg cm2, bar, psi and kpa, and the conversion relationship between them is as follows: 1 bar =.

Baiye Auto Parts Network suggests that the owner does not care how to calculate, just look at the position of the pointer on the barometer, what unit is used to mark this position, and then see what is the standard value of the corresponding air pressure unit of the vehicle. See how much difference there is between the measured value and the standard value, if it's too high, let off some air, if it's low, and make up the air until the tire pressure matches the standard pressure.

Check the tire pressure elimination method: After confirming that there is an abnormality in the wheel, it is important to see if the tire pressure of the wheel is high or low. If the tire pressure is too high and an alarm occurs, the tire gas can be slightly increased to the safe value of the tire pressure, and there is a tire pressure mark, which can be reset by pressing OK.

After the tire pressure indicator is on, it is first necessary to make sure that the car is parked on the side of the road in safe conditions, and check the tire pressure detection function of the abnormal wheels on the car's navigation screen. It shows that the tire pressure is too low, and you need to drive on the car for a while after resetting the tire pressure alarm to eliminate it.

First of all, check the tire pressure, then find the cause of insufficient tire pressure (whether it is punctured or caused by insufficient tire pressure), and finally the tire pressure light is reset, and the road test car.

1. High tire pressure.

When the tire pressure is too high, the tire cord is overextended and deformed, and the middle of the tread will be convex, resulting in serious wear in the middle of the tire; The contact area with the ground is reduced, the adhesion is reduced, the car is more likely to skid, and the braking distance will be extended; The elasticity of the tires will decrease, the carcass will be stiffer, the vibration damping effect of the tires will be weakened, and the ride comfort of the car will not be good.

In addition, due to the increase in tension on the ply, the puncture resistance of the tire is reduced, and the probability of puncture will increase when encountering stones and uneven roads.

2. Low tire pressure.

When the tire pressure is too low, the middle of the tire tread leaves the ground, and the shoulders on both sides of the tire are seriously worn; The carcass deformation is large, the rolling resistance increases, and the fuel consumption of the car increases; Due to the softness of the carcass, it is repeatedly squeezed and deformed when driving at high speeds, and excessive heat generation makes the tires easy to age at high temperatures and more prone to punctures.

Tire pressure monitoring method.

1. Direct tire pressure monitoring: The connected tire pressure monitoring device uses the pressure sensor installed in each tire to directly measure the air pressure of the tire, and uses the wireless transmitter to send the pressure information from the inside of the tire to the first receiver module, and then displays the air pressure data of each tire.

When the tire pressure is too low or flat, the system will automatically alarm.

2. Indirect tire pressure monitoring: The working principle of indirect tire pressure monitoring is: when the air pressure of a tire decreases, the weight of the vehicle will make the rolling radius of the wheel smaller, resulting in its speed being faster than other wheels.

By comparing the speed difference between tires, the purpose of monitoring tire pressure is achieved. The indirect tire alarm system actually relies on calculating the rolling radius of the tire to monitor the air pressure.

3.Tire Intelligent Monitoring System (TPMS) Introduction: It has the advantages of both systems, it is equipped with direct sensors in two tires at opposite angles to each other, and equipped with a 4-wheel indirect system.

This composite system reduces costs compared to using all direct systems and overcomes the disadvantage that indirect systems cannot detect low air pressure on multiple tires at the same time.

If you are sure that the tires are not flat or have been repaired, then you can restore the data.

Tire pressure, strictly speaking, refers to the pressure of the air inside the tire. In car maintenance, the engine is the heart of the car, and the damage to the engine will lead to the exhaustion of the car's life, then the tire pressure is the blood pressure of the car, and the tire pressure has a vital role in the performance and power of the car.

Tire pressure should be checked frequently to ensure safety

1. Observe the condition of the tires before traveling. Radial tires - that is, commonly known as low-pressure tires, as long as the flatness is not too low, it feels very elastic when pedaled, and it is normal if it is not soft. High-pressure tire - it is a bias tire with an inner tube, and the shoulder part of the tire is not prominent from the front, commonly known as it"No cheek swelling"From the side, the contact with the ground is about the same as the usual area, which is normal.

2. Pay attention to the sound of the friction between the tires and the ground during driving, feel the buffer force when the road is not very flat, and feel whether the acceleration when refueling has changed compared with usual, these are all ordinary accumulated experience.

3. Under normal circumstances, go to a professional tire repair shop every week to check and replenish the air pressure.

Low tire pressure is when the air pressure in the tire is too low, resulting in low tire pressure. Inflating the tires increases the air pressure and increases the tire pressure.

The tire pressure is too low, the comfort is good, quiet and stable. But the rolling resistance is high and the fuel consumption is high. And it will also cause abnormal wear and tear of tires.

If the tire pressure is too low, the contact surface between the tire and the road surface becomes larger, which can easily cause serious wear on both sides of the tire and heavy steering; The rolling resistance of the car becomes larger, and the fuel consumption increases; And the tire is repeatedly squeezed and deformed, resulting in a large amount of heat, resulting in a puncture.

How to deal with too low tire pressure:

1. The first thing is to visually check whether the tires can continue to drive, and if they can continue to drive, slowly drive to the nearest tire repair shop for processing.

2. If the tire pressure is too low to continue driving, if there is a car inflator pump, you can inflate a little air, and then go to the nearest repair shop for treatment, or replace the spare tire, and then repair it.

3. If the above methods are useless, then call the 4S store and ask them to send a tire to deal with it.

1. Tire pressure monitoring sensor or tire pressure monitoring computer board is faulty. If the tire pressure monitoring sensor is broken and cannot be repaired, you need to go to a professional car repair shop to replace the tire pressure sensor.

Second, the tire pressure monitoring device is a simple tire pressure monitoring system, is the use of ABS ready-made sensing function to compare the number of rotations of the tire, the tire circumference of insufficient tire pressure also becomes shorter, so if one of the four tires is not enough, the number of rotations will be different from other tires when driving.

Third, this method requires the tire pressure to be several pounds less to detect, and if the tire pressure of four tires is the same low, it will be fine. Everyone knows that maintaining normal tire pressure is important for driving safety and fuel efficiency, so smart cars have this tire pressure monitoring device that automatically helps you do tire pressure checks to ensure driving safety.

Checking the tire pressure is to remind the car owner to detect if the tire pressure is too high or too low.

The reason why there is a prompt to check the tire warning is because it has the effect of anti-flat, fuel-saving, reducing wear and tear, you know, too high tire pressure will make the contact area between the tire and the ground smaller, which will lead to poor grip of the tire and affect driving safety.

When the vehicle is prompted to check the tire pressure, it means that there is a problem with the tire pressure. This is where we should stop and check the tires. If you have a tire pressure gauge in your car, you can use the tire pressure gauge to check if the tire pressure is normal.

If it is normal, it is a false alarm of the tire pressure system, so that you can continue to drive the car.

If the tire pressure is too high or too low, it is not advisable to continue driving, in which case we need to replace the spare tire and drive to the nearest repair shop of the vehicle for treatment.

What is the right tire pressure?

In summer, because the temperature is relatively high, the normal tire pressure of the car needs to be reduced, because the temperature is relatively high in summer, the temperature is relatively high, and the tire temperature of the car will also increase during the driving process, and the tire pressure will also increase.

Therefore, in the summer, the tire pressure should be lowered to the Kai car point, on the contrary, in winter, because the temperature is relatively low, the tire pressure should be higher than the normal value.

Please check the tire pressure, which indicates that one or more tires are under-stressed or high-pressure. The tire pressure check must be done while the tire is cold. Tire pressure can be checked using a tire pressure gauge or a tire pressure monitoring system.

The vehicle manual lists the vehicle's standard right tire pressure under various load conditions.

This parameter is also listed on the label next to the driver's door, and the standard tire pressure is approximately. Too high tire pressure can easily increase tire wear and can also cause punctures, while low tire pressure can increase fuel consumption and vehicle bumps.

In general, tire pressure can be lower in the summer and higher in the winter.

If there is a hint, it is that the tire pressure is insufficient or it is a puncture. It is worth paying attention to, and it is necessary to confirm and inspect the car as soon as possible.
