Why do tires look deflated, but tire pressure is normal?

Tires are a vital component, under normal circumstances, if you go out, the owner will definitely check the tire pressure of your car to see if your car is still "gas". So the question is, some car owners may find that their car obviously has enough tire pressure, why not long after, the tire is deflated again. There may be a lot of drivers who don't understand, let's take a look at why:

First of all, some vehicles will have their own tire pressure monitoring.

If the tire pressure is insufficient, it will automatically alarm, and the problem of insufficient tire pressure does not have to worry about the owner. In addition, for vehicles without tire pressure monitoring devices, car owners should develop a good habit of checking tires before getting into the car. See if the tires have deflated, or if the body has tilted a little, at this time the front wheel is losing air on one side.

There is also the feeling that the owner can't raise the speed when accelerating, and it may also be a problem with tire pressure.

Secondly, when driving, I feel that one side of the car will be slightly lower than the other three sides, and at the same time I feel that the tire noise becomes louder, at this time, it must be that the tire pressure on one side is insufficient, and it is recommended to stop for detection. Tell everyone how to judge the front wheel: when the tire pressure on one side of the front wheel is insufficient, release the steering wheel.

There will be a slight misalignment. Each tire has wheel teeth, we can judge whether the tire pressure is normal by looking at the number of contact between the wheel teeth and the ground, generally there are 4 or 5 tire teeth touching the ground, indicating that the tire pressure is just right at this time; Less than 4 indicates that the tire pressure is high; More than 5 means that the tire pressure is low, so you should inflate the tires in time.

Many people think that the tires of a car are the same as the wheels of a motorcycle, and they look a little different when they run out of air. In fact, today's cars basically use vacuum tires.

That is to say, there is a layer of "gas" inside and outside the tire, which looks flat but is actually not flat, and the tire pressure range is mostly between to, as long as this standard is reached when refueling, because the tire will be adjusted according to its own pressure! So if it still looks flat after filling up, you don't have to worry about this situation at all!

The tire pressure is obviously enough, why are the tires still a little deflated! Here's why.

When driving, I feel that one side of the car will be slightly lower than the other three sides, and at the same time I feel that the tire noise becomes louder, at this time, it must be that the tire pressure on one side is insufficient, and it is recommended to stop for detection.

The tires of some cars look very deflated and feel like they are about to run out of air, but when you take a tire pressure gauge and test it, you find that it is within the normal tire pressure range; Some tires seem to be very strong, but they are actually leaking and almost out of air. Here we have to talk about the relationship between the deformation amplitude of the tire and the tire pressure.

We can judge whether the tire pressure is normal by looking at the number of contact between the teeth and the ground, generally there are 4 or 5 tire teeth touching the ground, indicating that the tire pressure is just right at this time; Less than 4 indicates that the tire pressure is high; And more than 5 means that the tire pressure is low.

If you go far away, the owner will definitely check the tire pressure of your car to see if your car is still "gas". So here's the problem.

The vehicle will have its own tire pressure monitoring device, and the tire pressure will be reminded if the tire pressure is insufficient, and the tire pressure problem will lead to tire protection.

When it is insufficient, it will automatically alarm, and the problem of insufficient tire pressure does not need to worry about the owner.

Hello, obviously the tire pressure is normal, why does the tire still look a little low? In this case, you can drive to a repair shop or 4S shop and ask them to use a tire pressure gauge to measure it for you, it is possible that his pressure sensor has misreported the information.

The tire pressure of the car is obviously normal, why does it look a little deflated? Many people are wrong.

The tire pressure is obviously enough, why are the tires still a little deflated! Here's why.

In fact, it is normal for the tire to be a little deflated. That's due to the fact that the tires used now are all vacuum tires, and the normal tire pressure is. As long as the standard air pressure specified in the vehicle manual is reached when refueling, it is fine, regardless of whether it is a little deflated.

However, car owners must pay attention to the fact that the tire pressure must be just right, not too high or too low, otherwise it will aggravate tire wear.

Why do the tires parked there look a little flat, and why do the old drivers ask us to pump up more? Let me tell you. When the car factory came out, the inflation pressure of the front and rear tires, my car was and, but with this pressure, the tires looked a little deflated, because this is the pressure of the tires, after the cold car runs for a certain distance, the friction between the tires and the road surface will cause the tires to heat up, and after the tires are heated, the air in the tires expands, which may cause the tire pressure to rise.

In the past, taking my own car as an example, and the tire pressure will rise to and, if you drive for a long time or brake more frequently, the tire pressure will rise to and, high tire pressure will cause your tread, then the contact surface that touches the ground will become smaller, see the decorative pattern of the tire, only the grinding disc in the middle, the tire pressure is high.

Excessive tire pressure has a greater safety hazard on braking and driving safety, a smaller contact surface means that your braking force is reduced and you need a longer braking distance, and too high tire pressure will cause your tires to have an accident and will be more prone to punctures. So why did the old driver ask us to put the tire pressure a little higher? Because the tire pressure given to you by the car factory, the tire pressure is safe when the tire is cold is not the state of gas is enough, if it is not used for a long time, it has been parked, it will cause the tire to deform laterally, as we said, it looks a little flat, the state has been fixed, which will cause the tire side rubber to age and crack, this is my own, not much, a few years later, I found that there is a circle of fine lines on the side of the tire near the hub, and some even crack very seriously.

Every time I did maintenance, the young man said to me, it's time to change your tires. So now I hit the tires to and, so that when driving long distances and high speeds, the tire pressure will rise to and, so that it can withstand and stop for a long time without damaging the rubber. Your own car, your own maintenance, is the guarantee of safety.

Why?

Because the tires of cars are different from the tires of other vehicles, such as the tires of motorcycles, the tires of motorcycles look deflated when there is no gas, and now cars basically use vacuum tires, that is, there is a layer inside and outside the tires"gas"The vacuum of normal tires is between pressures. This means that it doesn't matter if the tire has a puncture as long as the pressure is up to the mark. The reason why it looks deflated is because the car tires adjust to their own pressure.

This is a normal phenomenon, now the sedan is all radial tires, which itself is relatively flat, plus the engine and gearbox in the front, which increases the weight of the front wheels, and looks flatter.

It is recommended that you drive to the 4S shop to check it, ask them to use a pressure gauge to help you measure, to see if it is a false alarm information of the pressure sensor, the owner must pay attention to the tire pressure, must ensure that it is just right, not too high or too low or will aggravate the wear.

This situation is normal because the tires are elastic and therefore will definitely be flattened by the weight of the vehicle.

Because there is still a certain amount of air leakage in the tire when driving, and secondly, because there is a certain problem in the installation of the tire, it will cause such an impact.

If the tire pressure of the car is normal, it is not bulging. Sometimes the wheels press something, such as a stone or something like that, it looks very deflated, but it doesn't actually affect the use. You can check the tire pressure frequently, so you don't have to worry about it if it's normal.

Nowadays, cars are all low-pressure tires with no inner tubes in them, so normal tire pressure looks like that.

The situation of the front and rear wheels is not the same, the engine is generally front-mounted, it looks like the same tire pressure is more deflated than the rear wheel, this is normal, if you want to know how much tire pressure is appropriate, you can look at the logo of your door.

The tire wall is soft, the support is weak, and even if the tire pressure is not low, it looks like the tire pressure is insufficient.

This is due to the characteristics of the tire itself.

Completely disagree with the above opinion, even if there is engine tire pressure, it will not look less. You check the air pressure, because your car is comfortable, unlike the big truck 12kg, your car and trucks or other cars will definitely feel less, psychological effect, I meet every day to buy a new car owners, are suspected that the air pressure on their tires is not enough, check OK please rest assured to use it!

Many car owners will have this habit before driving out, to see if the tire is punctured, remove the stones, and confirm whether the tire pressure is normal. But when they checked the tire, they found that the tire was deflated, but after checking the tire pressure, it showed normal, so why did this happen?

Generally speaking, if the tire pressure is too high, it is easy to increase the probability of a puncture, and driving on uneven roads will be very bumpy and the grip will be weakened. If the tire pressure is too low, it will limit the speed of the car, wear out the tires, and cause the car to deviate from the direction, which is difficult to control when cornering, which is very dangerous. Because in order to ensure the normal and comfortable driving of the car, the tire pressure must be kept within a reasonable range.

When a new car leaves the factory, the tire pressure is around or even higher, because it takes a certain amount of time to buy from consumers after leaving the factory, ranging from ten days to several sail months or even a year. If it is kept within the normal tire pressure range, the vehicle is parked for several months, and the tires are prone to problems, affecting sales. However, after the first insurance, the tire pressure will be adjusted to the left and right, in fact, the tire pressure between can ensure normal driving.

However, because some models belong to the front wheel drive, the engine is in the front, and the front part of the car is heavier, so the tire pressure of the front tire will be slightly higher than that of the rear tire.

When the tire pressure is normal, the tire looks deflated, which is actually a normal phenomenon. For example, if you press a ball hard, the ball will naturally deflat. Similarly, the tires used in cars now are basically empty tires, many of which do not have inner tubes, and the wheels need to bear the weight of the whole vehicle, and the tires will also undergo a certain elastic deformation.

If you put the car on the elevator, the tires will naturally return to full circle. It may be that the owner is concerned about whether a tire that looks a little shriveled at the front is potentially dangerous. The answer is no.

It has nothing to do with tires. As long as the tire pressure is within the normal range, there is no problem, and the owner can be greatly relieved.

Millions of car purchase subsidies.

Tires are one of the necessary conditions for a car to run. If something goes wrong with the tires, the car won't be able to drive, so many car owners have a habit of checking if the tires are normal before driving at high speeds or long distances. Sometimes they notice that the tire is a little flat, but after testing, the tire pressure is normal.

What is the reason?

Many people may think that car tires are the same as bicycle tires, and they will deflat a lot when they are deflated. In fact, the tire pressure is normal, and it is normal for the tire to be deflated a little, because the current cars are basically vacuum tires, which actually look a little deflated, but as long as the tire pressure is in between, there is no need to worry about affecting the normal driving of the car.

The tires look a little flat. In fact, it is related to the puncture rate of tires. The aspect ratio is a piece of data for tires that refers to the percentage of the height of the tire's cross-section to the maximum width of its cross-section, i.e., the aspect ratio.

For example, the specification of 205 60 R15 tires, 205 means that the width of the tire touching the ground is 205mm (that is, the maximum width of the cross-section), 60 is the flatness ratio, the inner diameter is 15 inches, and the cross-sectional height of the tire is 205*60%=123 mm. Due to the long walls, high cushioning capacity and high comfort of the tires, sports car tires usually have a high flattening rate.

Moreover, many cars are now equipped with tire pressure monitoring devices. If the tire pressure is abnormal, this device will automatically alarm, so the owner should not worry too much about the abnormal tire pressure. If you don't have a tire pressure monitoring device installed on the car, you can drive the car to flat ground, observe the part of the tire that touches the ground, and remember the number of patterns that touch the ground.

Generally, 4 to 5 teeth on the ground is normal tire pressure. In the case of a front-wheel drive car, it is normal for most of the weight to be concentrated in the front of the vehicle, and the number of teeth touching the ground is higher than that of the rear wheels.

This is normal.

The lightest curb weight of the car is about 1 ton, and the average weight of ordinary compact cars is between tons, so even if there are four tires to share such a large weight, there will be a large load.

The tire itself is not supportive, what really plays a supporting role is the air inside the tire, and the air can be compressed; The greater the weight, the higher the degree of compression of the air, so even if the tire pressure is normal, the position of the tire on the ground will be flattened, and this normal phenomenon will not affect safety.
