What is the inflation pressure of a high pressure tire?

According to the use of standard air pressure, it is divided into two types: fixed air pressure tires and pressure regulating tires. Stationary pneumatic tires are now widely used. There are three types of air pressure.

High-pressure tires: 490 686kpa (5 7kgf cm2). Low-pressure tires:

The air pressure is 147 490kpa (. Ultra-low pressure tires: Air pressure is 147kpa (below.)

Ultra-low pressure tires and pressure regulating tires are suitable for driving on gravel roads, snow, swamps and desert areas, reducing the depth of tires stuck in soft roads and making the car easy to drive.

The inflation pressure of high-pressure tires is generally 500 kPa.

The common 55-65 flat ratio width 195-225 range, the maximum tire pressure does not exceed 3bar The standard tire pressure is, and the family car is controlled between 2 and 3 according to different environmental conditions or tire model standards, levels or actual specifications, that is, the staff of the 4S store.

For details, please refer to the "User Manual" when accompanying the car, and use it as standard! 36psi is just a unit value that can be converted to atmospheric pressure value kpa. Each car series, whether it is a large truck or a small car, will have its own special tire conditions or standards, not all vehicles use the same specifications of tires, even the same tire pressure!

Therefore, it is correct to refer to the actual (standard) air pressure of the tire.

Tire inflation internal pressure.

Tyre Inflatable Internal Pressure[1]tyre inflalian pressure Tyre at the ambient temperature. The pressure of the gas (liquid) body charged according to the standard regulations, excluding the internal pressure that the tire increases in use, is the gauge pressure measured when the valve is in any position; For a tyre that is filled with liquid, it is the gauge pressure measured with the air and water gauge when the valve is at the bottom. This refers to the measured value at ambient temperature.

Tire pressure monitoring.

Tire pressure monitoring, also known as TPMS, is a real-time monitoring of the air pressure and temperature of automobile tires, displaying tire pressure and temperature values, so that car owners can grasp the tire pressure and temperature at any time. Timely detection of tire leakage, insufficient air pressure, high air pressure and other conditions to avoid traffic accidents caused by punctures. At present, the United States has stipulated that tire pressure monitoring is a mandatory configuration for automobiles, and Chinese car owners do not pay enough attention to the safety hazards of tires.

However, there are already some tire pressure monitoring on the market, including the original car and some high-end cars that are equipped with tire pressure monitoring. At present, the best pressure monitoring manufacturer in the world is Schrader in the United Kingdom. The brand's tire pressure monitoring has been the leading company in China (Yu's Automotive Electronics Shanghai).

There are also many small manufacturers in China that produce tire pressure monitoring, but the technology is not mature enough, I believe that these manufacturers will gradually become stronger, so that Chinese brand tire pressure monitoring has also become a standard product in Chinese cars.

The common 55-65 flat ratio width 195-225 range, the maximum tire pressure does not exceed 3 bar, and the standard tire pressure is.

Exact tire pressure, look at the sidewall of the tire, the number behind the English psi = 1bar

Choose according to the manual, and generally about it.

Air pressure is the lifeline of a tire, and too much and too low will shorten the life of the tire. If the air pressure is too low, the deformation of the carcass will increase, the sidewall is prone to cracks, and at the same time, it will produce flexural motion, resulting in excessive heating, promoting rubber aging, cord layer fatigue, cord breakage, and will also increase the tire grounding area and accelerate shoulder wear. If the air pressure is too high, the tire cord will be subjected to excessive stretch deformation, the elasticity of the carcass will decrease, and the load on the car will increase during driving, and the impact will produce internal cracks and bursts, and at the same time, the high air pressure will also accelerate the wear of the tire crown, and reduce the rolling resistance.

When the car leaves the factory, it will provide a recommended tire pressure.

force, usually affixed to the inside of the B-pillar, fuel tank cap, or in the manual. Generally speaking, it is safe to have a tire pressure in a family car, and it is appropriate to have a slight drop in tire pressure in the summer. Inflation pressure is MPa; Low-pressure tires are generally suitable for private cars; Usually domestic cars.

Pneumatic tires are pressed. high-pressure tires; The inflation pressure is MPa. High-pressure tires are suitable for large trucks.

Passenger car. The inflation pressure is generally around the left, and the inflation pressure for low-pressure tires is; Low-pressure tires are generally suitable for private cars; Usually, the pneumatic tire pressure of domestic cars is <>

The inflation pressure is generally around megapascals, steel wire tires.

It can be appropriately increased to about megapascals, and the specific pressure of each tire is subject to the recommended value of the car manufacturer. This is because the tire pressure is mainly set taking into account vehicle factors such as body weight and chassis height. It doesn't have to be about what brand of tires you use. Standard air pressure.

It can usually be found in the following places, the vehicle's owner's manual, the label next to the cab door, the drawer next to the vehicle's driver's seat, the fuel tank cover door. The manufacturer's recommended tire pressure value refers to the tire pressure value of the vehicle when it is cold. At least three hours after stopping or when the tires have traveled no more than 2 km.

If the tire pressure can only heat up in the tire.

When measuring, subtract joba from the measured tire pressure, which is the tire cooling inflation pressure.

The standard tire pressure of most cars is in between, mostly around the right, so charging to an approximate value is not standard. But it won't be much worse than the standard tire pressure, not to mention the standard tire pressure for many cars. To save time, the workshop doesn't check the standard tire pressure for each car, so it's been a tradition for many years.

It is recommended that every car owner should know the standard tire pressure of their car, which varies. Generally, a piece of paper will be pasted on the fuel tank cap, door side, and B-pillar to indicate the standard tire pressure of your car. Find these three places yourself.

After inflation, it is best to inflate according to the standard tire pressure, so that the best performance of the vehicle can be brought out. It will also extend the life of the tires and do not allow punctures. Someone once asked how much lower the tire pressure is than the standard value and should be inflated.

As the contact area between the tire and the ground becomes smaller, the grip will be reduced, and it is easy to slip and the braking distance.

It will also get longer. If the tire pressure is low, it will consume the engine oil and shorten the life of the tire. If the sidewall of the tire is bent when the tire is dented, it will be more severe and the deformation will be greater.

During driving, the sidewall of the tire is always in a state of deformation recovery, due to the large amount of deformation, the heat generated is large, which accelerates the aging of tire rubber and cord. So the tire pressure is low.

The standard tire pressure is calculated by the manufacturer according to various factors, which can achieve the best safety, fuel economy and tire life.

There are relevant standards for the same pressure, and there are relevant standards for inflating car tires, and random inflating will also lead to punctures, which is dangerous.

When the tire is inflated, it is generally a pressure, which can be selected according to the model of the car.

, this is relatively standard, generally speaking, this is the value, just look at the manual.

Tire pressure values are normal in between. 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.

Standard air pressure can usually be found in the following places: the vehicle's owner's manual, the label next to the cab door (near the B-pillar), the drawer next to the driver's seat of the vehicle, the fuel tank cover door.

The effect of high and low tire pressure.

When the tire pressure is insufficient, the tire is easily damaged under the action of external load, and if you continue to drive, it is likely to lead to safety problems such as tire bursting.

Because tires are an important part of the load-bearing capacity of the entire vehicle and are constantly rubbing while driving, losses are inevitable. Therefore, we need timely maintenance to prevent the occurrence of puncture incidents while the car is driving.

Avoid under- or over-pressure in the tires, which can lead to wear and tear and can be dangerous. Insufficient tire pressure will reduce the durability of the carcass; Increases the resistance of the tire movement, resulting in an increase in fuel consumption. Excessive tire pressure can reduce the grip of the tire, leading to irregular wear of the tire, especially those mounted on the drive shaft.

Hello. The tire pressure of the general car tire is about the same. Or converted to a common unit of 250kpa, generally in the car fuel tank cap or B-pillar there is a hint, the vehicle tire pressure range it is divided into full load and no load. It is recommended to refer to the owner's manual.

Refer to the vehicle or tire technical manual.

Average: Standard tire pressure:

Tire pressure enhancement:

Maximum tire pressure: not greater than.

Tire pressure for low-pressure tires:

High-pressure tire pressure: 5 7bar (500 700kpr) low-pressure tires commonly used in private cars, generally charged 2 according to the comfort of their own mastery), SUV can be higher, around.

In addition, the recommended inflatable air pressure is usually posted on the side of your door.

The normal tire pressure of the car is between, the tire pressure refers to the pressure of the air inside the tire, the engine is the heart of the car in car maintenance, the damage to the engine will lead to the exhaustion of the car's life, 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. Automobile tire is one of the important parts of the car, it is in direct contact with the road surface, and the car suspension together to alleviate the impact of the car when driving, to ensure that the car has a good ride comfort and driving smoothness, and to ensure that the wheels and the road surface have good adhesion, so as to improve the traction, braking and passing of the car.

Generally, the normal tire pressure of the car is around the right, which is a standard, but not all models will be based on this standard, for example, the tire pressure of the SUV model will be a little higher than that of the sedan model, so the specific standard is still given by the manufacturer, and it is generally displayed in the vehicle owner's manual or the sign next to the door (B-pillar or C-pillar attachment), where you can see the manufacturer's recommended value (cooling tire pressure).

Tire pressure is the life of the tire, if you want the tire to be in good working condition, you must first ensure that the tire pressure is correct and appropriate, but the tire pressure is difficult to control 100% accurately, it can be slightly higher but not too low.

Precautions for the use of tires.

Always check the tires for abnormal wear and see if the tread depth on both sides of the tires is consistent. Tires have wear limit position markings that must be replaced when the tires wear to this mark.

In order to get the best tire condition, tire rotation is a must. At present, most cars are front-wheel drive, and the front wheels are steering wheels at the same time, and the wear is relatively large, generally in order to reduce the wear of the front wheels, a four-wheel replacement is carried out every 10,000 kilometers or so, and it is best to replace it diagonally.

The maximum air pressure bearing capacity of the car tires used in ordinary times is about 300kpa-350kpa, which is what we usually call atmospheric pressure. This value is not fixed, and the maximum air pressure capacity of different types of tires is different. You can check for yourself, every tire has this logo.

The maximum air pressure value is mainly related to the structural strength of the tire itself, the better the structural strength of the tire, the stronger the bearing capacity of the tire pressure, and the greater the bearing capacity. The tire pressure of large trucks is generally above 12 atmospheres, which is because the truck tires have a large load capacity, so the tire pressure must be high and the tire structure must be strong.

The normal tire pressure of the car is around the right, and there is still a lot of margin for this distance, so even if the tire pressure is slightly high, there is not much of a problem. We usually only need to inflate it according to the manufacturer's requirements. There are many people who think that it is better to have a lower tire pressure, and a lower tire pressure will not cause a puncture, but in fact, a puncture is largely caused by tire aging, and high tire pressure is only a part.

When the standard air pressure of the car is at its highest:

1.Loading load:

Full load: When fully loaded, the upper limit of the car tire pressure standard is applied.

2.Tire pressure measurement environment:

Hot tires: The tire pressure of cool tires and hot tires is not the same, and the difference between the two should be about bar;

Cold tires: at least three hours after stopping or no more than 2 km on tires;

If you can only measure tire pressure when the tire is warm, subtract the measured tire pressure from about the tire cooling and inflation pressure.

3.Driving conditions:

The road surface with a large bump is appropriately adjusted according to the standard air pressure of automobile tires, and the tire pressure is lowered;

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.

4.Tire Condition:

New tires: The tire pressure can be adjusted by about bar according to the standard air pressure of automobile tires;

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;

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

Hard tires: i.e., steerable tread tires, according to the lower limit of the standard tire pressure.

Generally, the tire pressure of a car is from the individual pressure.

It depends on what kind of car you have, and under normal circumstances, you can charge four wheels.

At the same time, you can also look at the tips on the side of your door, and inflate it as required.

At the same time, like this tire pressure, you have to test it once for maintenance, and you usually have to inflate it when you see it.
