Is it normal for me to have a tire pressure of 2 0 before and 2 1 after 2 1?

Hello! Proper tire pressure is the most important part of tire maintenance. The standard tire pressure of the tire depends on the vehicle on which it is installed - that is, the tire pressure marked on the vehicle door or fuel tank cover, which is the standard value determined by the vehicle manufacturer in the design and manufacture to give full play to the best performance of the vehicle, and the difference is generally allowed to be within 10%, if it is lower than the standard value of more than 10%, it is a state of lack of air; If it is less than 20% of the standard value, you should go to a specialist shop as soon as possible to check the cause - whether there is any damage or air leakage.

The tire pressure should be measured when the tire is cooled - that is, before leaving the car, and the valve cap should be tightened after the tire pressure is measured. Generally speaking, the tire pressure will decrease by about one month on average; Temperature also has an effect on tire pressure, which usually rises and falls by 10°C.

It is not necessary to turn the tire pressure up in the winter, but it is important not to turn it down in the summer.

When driving at high speed for long distances (especially in hot summer), you can appropriately increase the tire pressure ( to reduce flexion heat generation and avoid punctures.

When driving in bad road conditions, the air pressure can also be increased appropriately (to reduce tire damage.

In general, it is in this range, and you have to see, if it is an SUV, it is not the same as a car, a high SUV, some cars are lower, and the specifications of the tires are also different, so what kind of tire specifications do you want to see?

Hello, this is normal. It is recommended to charge the tire pressure to the left and right, as low tire pressure is easy to accelerate tire wear. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

It is not a normal situation, the tire pressure is a little low, the normal value of the tire pressure of the vehicle is between to, the tire pressure value of the vehicle is low, which will lead to an increase in the fuel consumption of the vehicle, the driving stability of the vehicle will be affected, and the tire will burst in serious cases.

If the tire pressure is not normal, it is recommended not to continue driving and should stop for monitoring. The tire pressure value of car tires is usually safe, as long as it is within this range.

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 of the engine will lead to the exhaustion of the car's life, so the tire pressure is the blood pressure of the car, and the tire pressure plays a vital role in the performance and power of the car.

Low tire pressure has an impact:

1. The friction coefficient of the pavement increases, and the fuel consumption increases;

2. The steering wheel is heavy, easy to deviate and other factors that are not conducive to driving safety;

3. Increase the movement of all parts of the tire. Excessive rolling can cause the tires to heat up abnormally;

4. Reduce the performance of the cord and rubber, resulting in the breakage of the cord and delamination or excessive friction between the rims, resulting in bead damage and abnormal wear;

5. The friction between the tire and the ground increases, the tire temperature rises sharply, the tire becomes softer, and the strength decreases sharply. When the vehicle is driving at high speeds, it may cause the tires to burst;

6. If the tire pressure is too low, it will increase the deformation of the carcass, cause cracks on the side of the tire, and produce deflection movement, resulting in overheating, rubber aging, tire fatigue, and cord breakage, increasing the tire grounding area, and accelerating the wear of the tire shoulder.

Normal. If you often run long-distance and high-speed, then the tire pressure should not be too low, and the air pressure should be increased according to the tire standard; If you often run on a large road surface, appropriately adjust the air pressure according to the tire standard; The normal situation is negligible.

When the tire pressure is insufficient, the deformation of the tire pressure will increase when the tire pressure rolls, and the tire structure will fatigue rapidly, which will easily lead to a puncture;

However, too high tire pressure will also lead to a puncture, that is because the high temperature gas expansion makes the air pressure beyond the tolerance range of the tire, generally the tire we use can withstand the air pressure on the left and right, on the side of the tire we can see the maximum air pressure that the tire can withstand.

Hello, I am a master with decades of experience! I've seen your problem! I will reply to you within five minutes, and after answering, if you are satisfied, can you give me a thumbs up? Thank you!

Hello, I looked at your **, normal ha, this is not a question at the moment.

So why is this still happening, and what is the reason?

AskedOkay, got it. Thank you, don't you need to fix it now.

It's okay, it's okay, if you can, please give a thumbs up, thank you!

Ask a question uh-huh, okay.

Answer: Thank you. I was worried about what exactly caused it. Is there a fault to answer this is the problem of the car running for a long time, not a failure, you can rest assured more 11

The car tire pressure display is still significantly low, generally speaking, it is normal for private car tires to be pressed between, you can refer to the tire pressure range on the back of the car fuel tank cap.

If the tire pressure warning light is lower than the car, you should pump up.

The tire pressure of the car is slightly lower than the normal range, generally speaking, the normal tire pressure of the car is between, too high or too low will affect the normal driving of the car.

When the tire pressure of the car is too high, it will reduce the stability of the car at high speeds and increase the chance of a flat tire in the car. If the tire pressure of the car is too low, it will accelerate the wear and tear of the tires, increase the fuel consumption of the car, and reduce the handling of the car.

Tire pressure is normal.

Under normal circumstances, there is no safety hazard to tire pressure. Because the tire pressure is in the normal range. There is only one exception: in the winter, the tire pressure is a bit low.

In the vast majority of cases, it is normal for a tire to be pressed in between.

In winter, try to keep your tires at a higher pressure. Because of the thermal expansion and contraction of tires, the tire pressure in winter will be lower.

It should be noted that the tire pressure usually refers to the tire pressure in the cold car state.

The tire pressure is too low, and the tire pressure must be replenished in time. Because the tire pressure is too low, the deformation of the carcass will increase, and the contact area with the ground will increase.

First of all, it will cause the sidewall to wear first, accelerate the wear of the shoulder, and the sidewall is prone to cracks. And the sidewall is the thinnest part of the tire.

Due to the increase in the contact area with the ground, flexural motion (increased friction) is generated, and the fuel consumption of the car increases.

In turn, it will cause abnormal heating of tires, tire temperature rises sharply, promote rubber aging, cord breakage, tire softening, strength drops sharply, and the danger of tire bursts occurs.

The standard value range of tire pressure, this generally different models, the relevant tire pressure factory regulations are also a certain deviation, however, taking family cars as an example, under normal circumstances. Tire pressure can be kept within the range.

Hello, I am glad to answer your question that the tire pressure of the car is not normal, it is lower than the normal range, and the normal tire pressure of the car is between bar. The hazards of low tire pressure: 1. The friction coefficient of the road surface increases, and the fuel consumption increases; 2. The steering wheel is heavy, easy to deviate, and it is not conducive to driving safety; 3. Increase the movement of all parts of the tire, excessive rolling will cause abnormal heating of the tire; 4. Reduce the performance of the cord and rubber, the cord is broken and the delamination or excessive friction between the rim is caused, resulting in damage to the tire port and abnormal wear; 5. The friction between the tire and the ground increases, the tire temperature rises sharply, and the tire softens and the strength decreases, which will lead to tire bursting; 6. Low tire pressure will increase the deformation of the carcass, cause cracks on the side of the tire, produce flexural movement, lead to overheating, rubber aging, accelerate shoulder wear, and shorten the service life of the tire.

Questions. When I picked up the car in July, I didn't pay attention to it, I had already driven more than 1,000 kilometers, and there was no abnormal feeling, it should not hurt the tires too much, now it's cold, add to the line?

Normal tire pressure should be around the limit.

Questions. Thank you!

You're welcome, and I wish you a happy life and good night.

OK.

It is recommended that the tire pressure should not run at high speed, because the normal tire pressure range is between, and running at high speed at too low tire pressure will cause serious deformation of the sidewall and damage the cord layer, resulting in a puncture. And it should be noted that when running at high speed, in addition to checking the tire pressure, you should also check the damage to the tire.

Tire pressure precautions.

At high speeds, the risk of a puncture is very high. If the tire pressure is too high, and then quickly pass through obstacles or potholes, the tire will be squeezed violently in an instant, and the tire pressure will also become instantly high, exceeding the pressure that the tire can bear, causing a puncture.

If the tire pressure is too low, it can also cause a puncture. Because the tire is rubber, it bears the weight of the whole car, so the tire is deformed, and the part in contact with the ground is deformed the most, and when the tire is rolling and no longer in contact with the ground, the deformation will be restored. That is to say, when the car is driving, the tires are always in the process of deformation and recovery.

The tire pressure is normal in summer, and the standard tire pressure of common cars is up, which needs to be screened according to the specific situation. The standard tire pressure range of the car will be marked on the vehicle's instruction manual or the vehicle's ** column and fuel tank cap.

Winter tire pressure: based on the principle of standard air pressure of automobile tires, appropriately adjust the left and right; Tire pressure in summer: The car is parked in the open air, and the air pressure can generally be about lower than the standard to avoid high temperature puncture; Half-load tire pressure:

According to the lower limit of the automobile tire pressure standard; Full load tire pressure: At full load, it is the upper limit of the car tire pressure standard.

Hello, normal tire pressure needs to be kept in between.

Tire pressure is a bit on the low side.

The right car tire pressure.

1. According to the provisions and requirements of the international GBT2978-2008 standard:

Standard Tires: Reinforced Tires: Maximum Air Pressure: Should Not Be Greater.

Tire condition: New tire: The tire pressure can be adjusted about according to the standard air pressure of the car tire.

Old tires: Appropriately adjust the tire pressure according to the automobile tire pressure standard, and if the wear is serious, the lower limit of the automobile tire pressure standard shall be pressed.

Soft tires: tires with comfort patterns, which are appropriately adjusted according to the standard tire pressure.

The tire pressure is normal, and the tire pressure required by the general vehicle is the same, but this is actually a bit low, and it can be seen that the tire is still a little deflated when it is time, and it is recommended that the tire pressure is in this way.

What is the standard tire pressure for ordinary private cars? Experienced veteran drivers: just remember this number.

It depends on what road you are driving on, if you drive a little lower on a mountain road, you can add it to the left and right on the city road, and the comfort is better!

Will the tire pressure be a little low.

Generally, the tire pressure value is normal between them. If the seat is full (5 people), it is more suitable to adjust the tire pressure to the left and right; Generally, if there are two people, the tire pressure value is also normal.

According to the provisions and requirements of the international GBT2978-2008 standard:

Standard tires:.

Reinforced tires:.

Maximum air pressure: should not be greater than.
