Tire pressure always drops very quickly, what s going on

It is caused by a flat tire.

Solution: Change the valve core and replace the valve core with an explosion-proof one. Install a tire pressure monitor and monitor it.

Recommendation: Tires are mainly affected by a combination of factors such as air pressure, temperature, load, speed, road conditions, ambient temperature, continuous driving time, etc. For example, affected by the principle of thermal expansion and cold contraction, tires will naturally lose kilograms of square centimeter air pressure on average every month, and tire pressure changes with the change of temperature

For every 10 times the temperature rises, so does the air pressure. If you want to effectively extend the life of your tires, make it a habit to check your tire pressure at least once a month, and use a high-quality testing instrument to measure your tire pressure, not by the naked eye or by kicking.

Tire pressure, strictly speaking, refers to the pressure of the air inside the tire. The tire pressure of different models is definitely different, so it is necessary to inflate according to the standard tire pressure of the vehicle.

1. Where is the tire pressure of the standard tire?

1. Vehicle user manual; 2. The label next to the cab door (near the B-pillar); 3. A drawer next to the driver's seat of the vehicle; 4. Small door of fuel tank cover.

Second, the impact of tire pressure on driving:

1. Tire pressure is too high: The friction and adhesion of the tire will be reduced, resulting in steering wheel vibration and deviation, which will reduce the comfort of driving; Accelerate the local wear of the tread pattern of the tire tread**, so that the tire life is lowered; The vibration of the body becomes larger; It will cause the tire cord to be subjected to excessive stretch deformation, and the elasticity of the carcass will decrease.

2. The tire pressure is too low: the friction coefficient with the road surface will increase, and the fuel consumption will increase; The steering wheel is very heavy, easy to deviate and other unfavorable safety; The amount of movement of all parts of the tire increases, and excessive rolling causes abnormal heating of the tire.

3. What is tire pressure related to?

1. Seasonal factors: Generally speaking, in winter, the standard air pressure is appropriately adjusted to about the principle; In summer, according to the lower limit of the standard air pressure of automobile tires, the car is parked in the open air in summer, which is 0 lower than the standard1 or so.

2. Loading load: no-load or half-load according to the lower limit of the automobile tire pressure standard; When fully loaded, the upper limit of the car tire pressure standard shall be applied.

3. Tire pressure measurement environment: the tire pressure of cool tires and hot tires is not the same, pay attention to the difference between the two when measuring.

4. Driving road conditions: the road surface with large bumps should be adjusted to reduce the tire pressure according to the standard air pressure of the automobile tire; The amplitude is small, can be ignored, do not care; Running long-distance and high-speed, the tire pressure should not be too low, and the tire pressure should be increased according to the lower limit of the standard air pressure of the automobile tire.

5. Tire condition: The tire pressure of the new tire can be adjusted by about bar according to the standard air pressure of the automobile tire; The old tire should be adjusted according to the tire pressure standard, and if the wear is serious, the lower limit of the tire pressure standard should be lowered;

Fourth, comprehensive. Abnormal tire pressure will lead to uneven wear of tires, reduce the comfort of driving, and be more related to the safety of driving, and may lead to punctures in serious cases.

Generally speaking, the tire pressure is left and right. In the summer, it is slightly lower. At full load, press the upper limit, otherwise, lower the upper limit.

In addition, because the front wheels support the engine for a long time, the tire pressure is slightly higher than that of the rear wheels. Because the spare tire is not commonly used, the air pressure should be higher, so as not to lose the emergency function due to low air pressure. Generally should be higher.

Adjust the tire pressure when you use it, and inflate it to a high tire pressure after use. In addition, the tire pressure of cool tires and hot tires is not the same, so you should pay attention to the measurement. The gap between the two is about the same.

Hello. The tire pressure drops quickly, and it is obvious that it should be punctured, go to the repair shop to check it.

See if there are any nails, if not, there is an air leak on the edge of the hub.

If the tire pressure is too high, it is necessary to deflate by pressing the valve core, but it is necessary to use a tire pressure gauge to assist, so as to ensure that the tire pressure is put to the specified value, and the specific operation steps are as follows:

1. Prepare the tire pressure gauge.

2. Find the corresponding wheel valve core.

3. Remove the valve core cover and press the valve core.

4. Connect the tire pressure gauge to the valve.

5. At this time, the tire pressure gauge is the tire pressure.

Precautions for operation:1. Air pressure cannot be supplemented, so do not continuously deflate too much.

2. Excessive tire pressure will increase tire wear.

If you unscrew the plastic cap of the tire valve and gently press the valve core with an object such as chopsticks, you will hear the exhaust sound and feel the air discharge, and let it go. While exhausting, use the tire pressure gauge to measure the actual tire pressure against the tire pressure mark on the side of the tire until it reaches the standard.

Dangers of high tire pressure:

1. High tire pressure will reduce the friction and adhesion of the tire, affect the braking effect, and also affect the life of the tire;

2. High tire pressure will lead to a decrease in tire puncture resistance, which is easy to cause puncture;

3. Accelerate the local wear of the tread pattern of the tire, so that the life of the tire decreases, and the vibration of the body becomes larger, which indirectly affects the life of other parts;

4. Excessive tire pressure will also cause excessive stretch deformation of the tire cord and decrease the elasticity of the carcass, which will increase the load of the car during driving and reduce the rolling resistance. When encountering sharp objects such as nails and glass on the road surface, it is easy to penetrate into the tire, and the impact will cause internal cracks and bursts, resulting in a puncture.

Hello, unscrew the tire valve and the core cap of the tire valve, and then press the spring core in the middle of the valve with your fingernails or something else to deflate.

You can open the air cap and poke the nozzle tip with a screwdriver. This is more convenient and not standard. Standard requires a special tool to release the tire pressure to (250kpa).

Hello, you can deflate the air core and observe the air pressure displayed on it.

Hello. The main thing is to have a barometer to put the standard, no watch is not accurate! It is recommended that the repair shop adjust it!

Tire pressureIt's normal to run too low for a while.

If the tire pressure sensor maintains RF communication even during the shutdown, this power consumption is very fast. Despite the low-power design, it still saves power. During the parking period, it will enter a quasi-sleep state, and when the vehicle is really running, it will maintain a continuous signal transmission state, and the tire pressure will slowly become normal if it is too low.

It may also be because of the weather, the weather is cold in winter, and the tire pressure is relatively low when the vehicle is just started, this phenomenon is normal, as long as the vehicle starts to run for a while, it will return to normal.

Precautions for car tire pressure:

1. If the tire pressure is too low, the deformation of the carcass will increase, the sidewall will be prone to cracks, and the contact area between the tire and the ground will become larger, which will accelerate the wear of the tire, and the fuel consumption will increase accordingly;

2. If the tire pressure is too high, the load on the car will increase during driving, and it is more likely to cause a puncture. At the same time, the tire noise will also become louder, and the road surface will be bumpy when encountering potholes, and the comfort will be greatly reduced.

Tire pressure. If the force is too high, it is necessary to deflate by pressing the valve core, but it is necessary to use a tire pressure gauge to assist, so as to ensure that the tire pressure is put to the specified value, and the specific operation steps are as follows:

1. Prepare the tire pressure gauge.

2. Find the corresponding wheel valve core.

3. Remove the valve core cover and press the valve core.

4. Connect the tire pressure gauge to the valve.

5. At this time, the tire pressure gauge is the tire pressure.

Precautions for operation:1. Air pressure cannot be supplemented, so do not continuously deflate too much.

2. Excessive tire pressure will increase tire wear.

When driving on a highway in the rain, a film of water forms between the tires and the ground. When the car reaches a speed of more than 80 kilometers per hour, the water film will completely separate the tires from the ground, and the tires will not touch the ground at all during driving, but will glide on the water like a motorboat.

At the beginning of the light rain, the dust and sand of the road surface have not been washed away, which greatly reduces the adhesion of the road surface. If the tires continue to maintain an abnormal low pressure state, they are more likely to slip and flick, causing potential safety hazards.

Tire pressure precautions.

It should be noted that the cold tire pressure is normal between the general recommended cold tire pressure, so that the fuel consumption will be lower, and the tire pressure can be controlled within the safe tire pressure range value when driving at high speed, in fact, the tire pressure requirements of different models are different, the maximum and minimum requirements for the tire pressure are different, and the tire pressure requirements for the same tire are different in different models.

Therefore, the optimal tire pressure is not a fixed value, but according to different models, the standard tire pressure value of each model is marked on the vehicle's user manual or on the inside of the fuel tank cap and the co-pilot position under the vehicle's B-pillar.

The reasons for the decrease in tire pressure are as follows: 1. Tire and valve leakage, which needs to be tested by the tire store. 2. The wheel hub is deformed, resulting in the reduction of tire sealing performance.

3. The vehicle is loaded with overweight items for a long time, and the tires are unevenly stressed. 4. Thermal expansion and cold contraction, due to the difference in the process of tires, it is possible that the tire pressure is insufficient due to thermal expansion and cold contraction. The method of judging the tire pressure in the driving process is as follows:

1. When driving, I feel that a certain side near the car will be slightly lower than the other three sides, and feel the tire noise getting louder together. 2. When driving, if you feel that a certain side of the four wheels will make a very rhythmic "pop" sound, and the rhythm sound will also increase with the speed of the vehicle or weaken the macro calendar, at this time, it should be a tire stuck to a slightly larger stone or nail, and the tire should be repaired when the tire is nailed. 3. It can be concluded through tire wear that the tire wear at both ends is severe, indicating that the tire pressure has always been too low, perhaps often overloaded, and the center is severely worn, indicating that the tire pressure is too high, and the wear on one side of the tire at both ends is severe, indicating that the four-wheel alignment is not done well.

4. If the tire is bulging, it is easy to blow out the tire if it is advocated to replace the tire, and there are many factors such as high tire pressure, impact, often driving on uneven roads, and often pressing the manhole cover to rush the road steps when driving. 5. For how much tire pressure needs to be added for each model, it is usually found in the maintenance manual, the door frame, or the fuel tank cap.
