Is it abnormal for the tire pressure of the car I just bought to drop from 2 3 to 1 5 in a few days?

Abnormal. According to the provisions and requirements of the international GBT2978-2008 standard: standard tires: , reinforced tires: . Check in time for a flat tire, tire pressure.

It is dangerous to drive too low on the road.

Dangers of low tire pressure:

1. Friction coefficient with the road surface.

This will increase and fuel consumption will increase.

2. Cause the steering wheel.

It is very heavy, easy to deviate and other factors that are not conducive to driving safety.

3. Increase the amount of movement of all parts of the tire, and cause abnormal heating of the tire due to excessive rolling.

4. The function of the cord and rubber is reduced, causing delamination or cord breakage and rim.

Excessive friction causes damage to the bead and abnormal wear.

5. The friction between the tire and the ground increases exponentially, the tire temperature rises sharply, the tire becomes softer, and the strength decreases sharply. If the vehicle is driving at high speeds, it may cause a flat tire.

Hello, this is not normal. Tire pressure is generally reduced within two months, it is recommended that you go to a nearby tire repair place to remove the tire and put it in the pool to see if there is any air leakage. Hope it can help you and have a great life!

Check to see if it's a leak

Hello, it's not normal, it's the air valve leaking.

Hello, it's all tires or one, if it's one, then it's possible to puncture the tire, just go to the place where the tire is repaired and make it up.

Hello dear! Thank you for waiting, if the tire pressure drops overnight, it means that the tire has nails, and the tire needs to be checked in time. If the tire pressure changes normally, there may be a change of 0.10.2, but if you drop the pressure by half a moment, then this pressure change is indeed a bit big, and the main consideration is to tie the nails in the tire.

This can spray a little foam water on the surface of the tire, and see that there are bubbles under the calendar, and it will be sold to explain that there is an air leak. Kiss!

If your tires drop overnight, then this is usually an indication of a gas leak. If there is no breakage or other factors that cause a sharp drop in intrauterine pressure, then this phenomenon is generally caused by the following reasons:1

Loose tire valve: If the tire valve is not completely closed or loose, it will cause the air locust body to leak, causing the tire pressure to drop rapidly. 2.

Broken tires or nail holes: If you hit an obstacle while driving or if your vehicle goes flat just a few minutes after entering an area like a construction site, road construction, etc., it's likely that your tire is damaged or punctured. 3.

Aging tire pads: If a tire pad is aged or damaged, it may fail to seal the gas, causing the tire pressure to drop. If you notice that your wheel pressure is lower than recommended, immediately go to a professional car repair shop to have it checked and refill the gas.

Timely maintenance and protection of tires can improve driving safety and extend the service life of wheel grinding tires.

Hello dear, if the vehicle is driving at high speed, the tire pressure of the vehicle will definitely rise. First, under normal circumstances, it is normal to go from rising to. Second, because the vehicle is driving at high speed, the frequency of friction between the vehicle, the tire and the ground is relatively fast, so the tire temperature will be high.

Third, under normal circumstances when this normal vehicle runs at high speed, the tire pressure is recommended to be kept within the range. Hello, I wish you a happy family, if necessary, you can continue to consult, I will always wait for your reply I wish you good luck, everything goes well, and a happy life! Kiss kiss kiss.

This is normal, the temperature gets higher after the tires are driven, causing the gas to expand. Tire pressure with increased air pressure.

It is also possible that the tires can withstand the pressure.

The maximum tire pressure should not be exceeded as normal during the driving process. The tire pressure should be based on the value recommended by the car manufacturer. This is due to the fact that the key to the calculation of tire pressure is to take into account vehicle factors such as the weight of the body and the height of the chassis.

In general, the tire pressure recommendation value refers to the tire pressure measured when the tire is cool; Tire cooling condition is defined as driving no more than 2 kilometers after parking for at least three hours. If only on hot tires.

When measuring tire pressure, subtract the measured tire pressure value from the pressure to cool and inflate the tire.

This is normal, the temperature gets higher after the tires are driven, causing the gas to expand. Tire pressure with increased air pressure can also be used, the pressure that the tire can withstand.

The maximum tire pressure should not be exceeded as normal during the driving process. The tire pressure should be based on the value recommended by the car manufacturer. This is due to the fact that the key to setting the tire pressure is to take into account the weight of the body, chassis height and other vehicle factors.

In general, the tire pressure recommendation value refers to the tire pressure measured when the tire is cool; Tire cooling is defined as stopping for at least three hours or driving no more than 2 kilometers on the tires. If you can only measure tire pressure when the tire is hot, subtract the measured tire pressure from the approximate bar tire cooling and inflation pressure.

Hello car owner, this is normal, the temperature becomes high after the tire is driven, causing the gas to expand. When the air pressure rises, there is no problem with the tire pressure, and the tire can withstand the pressure. I hope my answer is helpful to you, if you still have questions, you can feel free to ask me, I wish you a happy life [If you have a problem with the car, ask the car master.

If the tire pressure reaches the cold state, it is actually relatively low. It is recommended to charge the air pressure to the tire, which is the only part of the car that touches the ground, which is related to the driving stability and handling of the car.

Air pressure is important for tires, and the tire pressure cannot be too low or too high.

If the air pressure is too high, the contact area between the tire and the ground will become smaller, which will reduce the grip of the tire.

If the air pressure is too low, it will cause the tires to deform in waves at high speeds.

If the tire is deformed in waves, it will speed up the wear of the tire and increase the probability of a puncture.

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

Generally speaking, the tires installed in the car will last for four years, so it is recommended that you replace the tires every four years.

When buying new tires, you must look at the production date because tires also have a shelf life.

In general, the shelf life of unused tires is three years.

If it's been more than three years since it left the factory, don't buy it.

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

Summary. If it is a single tire, it may be punctured, leaking, etc., and if it is all tires, the pressure of the cold tire may be normal. After the car is driven, heat is generated in the tires, so it is normal for the tire pressure to rise (generally about bar higher than the cold tire), on the contrary, if the weather suddenly becomes cold, the tire pressure changes from a reduced bar, of course, the drop is still larger, you can first pump to supplement the tire pressure and then observe the situation.

If it is a single tire hail travel phenomenon, it may be punctured, air leakage, etc., if it is all tires, the tire pressure from cold to may be normal. On the contrary, if the weather suddenly becomes cold, the tire pressure changes from a reduced bar, of course, the drop is still larger, you can first pump to supplement the tire pressure and then observe the situation.

The owner's guide reminds you that different tire pressure measurement methods may not lead to excessive error in tire pressure value, and the tire pressure value is the tire pressure of cold tires, if the vehicle has been parked for at least 3 small quarrels, or driving less than km
