What is the tire pressure in a car? What is the normal tire pressure of a car?

1. Check the tire pressure gauge.

2. When there is no tire pressure gauge, look at the position of the gap between the tire and the ground, between the two gaps is considered a pattern, under normal circumstances, the number of tires against the ground is 4 to 5. When the number of sticking patterns to the ground is more than 6, it means that the air pressure is low, and when there are less than 4, the air pressure is high.

In summer, because the temperature is relatively high, the heat expands and contracts, and the normal tire pressure of the car needs to be lowered, which is 210 230kpa in summer. On the contrary, in winter, because the temperature is relatively low, the tire pressure can be slightly higher than the normal value, 230 250kpa in winter, it is best to read the car's manual.

Standard tires are for reinforced tires, and the maximum tire pressure should not be greater than.

The tire pressure value of the family car tire we use is generally kept in, the car tire is a very important part of the car, the tire pressure is the life of the tire, the tire pressure has a maximum and a minimum value, neither more than the maximum value, nor can it exceed the minimum value, otherwise it will affect driving safety.

When the climatic conditions are different, the tire pressure will be different, in the summer high temperature state, the tire pressure of the car tire can be slightly reduced, the winter can be slightly higher, whether high or low, can not exceed the normal tire pressure range value, because the tire pressure is too high, the contact area between the tire and the ground will be reduced, the pressure borne by the tire is relatively large, it is easy to cause certain damage to the tire, and at the same time aggravate the wear of the tire, if you encounter ground bulges or small stones, it is easy to cause a puncture.

When the tire pressure is too low, the contact area between the tire and the ground will increase, and the internal temperature of the tire will increase after a long time of driving, which will also affect the deformation of the tire, and will also increase the fuel consumption of the car and reduce the life of the tire.

Since pneumatic tires are widely used in automobiles, it is necessary to ensure a reasonable working condition through air pressure. Too high or too low tire pressure will cause abnormal wear and tear of tires, shorten the service life of tires, and even lead to the danger of punctures. Car tire pressure standards"Car tire pressure standards"When the tire pressure is higher than the design standard value, the tire will lose its due elasticity and shock absorption ability, not only the grip will become worse, but also the tire tread middle wear will increase due to the reduction of the tire ground contact area, and the wear of the middle of the tire tread will increase, and the tire rigidity will be increased at the same time, so that the dynamic load on the wheel will increase, and the carcass will easily burst.

The impact is even more severe on uneven roads or at high speeds. When the tire pressure is lower than the standard value, the deformation of the tire will increase during driving, and the shoulder wear on both sides of the tire will increase sharply; The carcass is twisted and deformed due to its inability to resist the pressure of the ground, resulting in high temperatures that accelerate the wear and tear of the tire, which can eventually lead to a puncture. Therefore, the normal air pressure of the tire should be maintained according to the manufacturer's requirements, including the spare tire pressure.

The normal value of the car's tire pressure" "The normal value of the car's tire pressure"Generally speaking, the normal tire pressure is around the left. In summer, it is slightly lower, and at full load it is the upper limit, otherwise, the lower limit is lowered. 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 effect due to low air pressure, which should generally be between. So how do you know what kind of pressure you need for your tires? The standard air pressure of a vehicle's tires can usually be found in these places on the car:

One is the vehicle owner's manual; the second is the cab door, which is the label next to the B-pillar; the third is the drawer next to the driver's seat of the vehicle; Fourth, the small door of the fuel tank cover; Fifth, the tire of the car is pressed near the door pillar or on the fuel tank cover, or look at the side of the passenger door of your car.

The tire is very important for a car, because it determines the driving state of the car, but it is the tire pressure that determines the tire, which is the air pressure inside the car tire, which has a decisive role in the car tire.

Hello, the normal tire pressure of the car is hope it helps you!

Car tire pressure is generally normal.

It is normal within the range of arrival.

If the tire pressure is too low, the area in contact with the ground will become larger, on the one hand, the friction coefficient between the tire and the ground will increase, on the other hand, it will cause the tire to roll to the bottom, the cord in the sidewall rubber cord is compressed and deformed too much, when the tire rolls to the top, the cord will return to its original position under the action of elasticity and tension, which will make the internal cord layer deform, accelerate fatigue, and cause structural damage in serious cases.

In the left and right.

Tires are an important factor for the safe driving of cars, and tire pressure is to maintain the life of tires, so standard tire pressure is extremely important. Many people have a vague concept of tire pressure, unless there is a leak or a broken tire, otherwise they will not care how much tire pressure is played.

Generally, the tire pressure of ordinary cars can be controlled around the right, but the standards of different models are not the same, the specific need to control the tire pressure in what range, please refer to the car user manual or the door and other position of the label, pay attention to the tire pressure is a good habit, but there is no need to fidget for the tire pressure difference, if the car is not equipped with tire pressure monitoring, prepare a tire pressure gauge or install tire pressure detection can be more timely to understand the tire pressure.

In summer, because the temperature is relatively high, the thermal expansion and contraction, the normal tire pressure of the car needs to be lowered, because the temperature is relatively high when driving in summer, the tire temperature of the car will also increase during the driving process, and the tire pressure will also increase, so in the summer, the tire pressure should be lowered to the point; On the contrary, in winter, because the temperature is relatively low, the tire pressure should be higher than the normal value.

Dangers of low tire pressure:

When depressed, the tires are soft, and when they are driven, they deform more. Each part of the tire will come into contact with the ground once it turns, and the lower the tire pressure, the longer it will take for the deformation to recover. In other words, the lower the tire pressure, the faster it drives, the more likely it is to produce standing waves.

This phenomenon causes the temperature of the tires to rise rapidly, and the result is a puncture.

1. The friction coefficient with the road surface will increase, and the fuel consumption will increase.

2. The friction between the tire and the ground increases exponentially, the tire temperature rises sharply, the tire becomes softer, the strength decreases sharply, and the vehicle travels at high speed, which may lead to a puncture.

3. If the tire pressure is too low, the deformation of the carcass will increase, and the sidewall will be prone to cracks, and at the same time, there will be flexural movement, resulting in excessive heating, promoting rubber aging, cord fatigue, cord breakage, and increasing the tire grounding area and accelerating shoulder wear.

4. Make the steering wheel of the vehicle heavier, easy to deviate, worse handling and greater tire noise.

Dangers of high tire pressure:

When the tire pressure increases, the tire becomes stiffer, the effective ground area is reduced, and the rolling resistance is reduced accordingly, so it is fuel-efficient. But don't forget, the braking effect when braking is also directly related to this ground contact area. There are pros and cons, a few liters of gasoline are only a few dozen yuan, and if you can't stop it, it's a big deal.

1. The friction and adhesion of the tire will be reduced, which will affect the braking effect.

2. It leads to steering wheel shaking, deviation, and reduced driving comfort.

3. Accelerate the local wear of the tread pattern of the tire, which can easily lead to tire bulging and stones.

4. The tire cord will be subjected to excessive stretching and deformation, and the elasticity of the carcass will decrease, so that the impact of the car during driving will increase, and the driving noise will increase.

5. When encountering sharp objects such as nails and glass on the road, it is easy to penetrate into the tire, and the impact will produce internal cracks and cause punctures.

According to a report released by the National Highway Traffic Safety Administration (NHTSA), a tire pressure 25% lower than the standard value increases the chance of a puncture by 3 times; 25% higher than the standard value, the chance of a puncture is doubled.

Usually the correct tire inflation pressure is between the standard tire inflation pressure (cold tire pressure). In the case of no load, ordinary cars are generally around bar, and off-road tires are.

Tyre pressure that is too high or too low can lead to shortened tire life.

The user manual is cold tire 240, and there is also a mark on the door frame of your co-pilot, you are a little low, the weather will be cold, the colder the lower, go wash the car and make up for it by the way.

Generally, the normal tire pressure of the car is left and right, which is a standard.

However, not all models will be based on this standard, for example, SUV models will have a little higher tire pressure than sedan models, so the specific standard still depends on the manufacturer, and it will generally be 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).

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.

Generally speaking, the normal tire pressure is based on the manufacturer's recommended value. Tire pressure standards vary depending on the type of tyre and the type of tyre, and the required tyre pressure varies from vehicle to vehicle with different vehicle weights, heights, and tire sizes.

The tire pressure is 240kPa-250kPa for standard tires and 280kPa-290kpa for enhanced tires. Moreover, the tire pressure of cool tires is also different from that of hot tires, and the pressure of hot tires is about 20kpa higher than that of cold tires.

The manufacturer's recommended value is the tire pressure value of cold tires, and the tire pressure in the cold car state is about 230kpa-250kpa, but the specific tire pressure marked on each car shall prevail.

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. Standard air pressure can usually be found at:

The owner's manual of the vehicle, the label next to the door of the cab (near the B-pillar), the drawer next to the driver's seat of the vehicle, the small door of the fuel tank cover. The amount of tire pressure should be based on the recommended value of the car manufacturer. This is because the tire pressure is set mainly taking into account vehicle factors such as the weight of the body, the height of the chassis, etc.

It has nothing to do with what brand of tires are used. If there are no special regulations from the depot, there is no need for special adjustments in winter or summer. Of course, it is recommended that you measure tire pressure at room temperature.

Generally, it is recommended that the front and rear wheels be the same as much as possible, and if the load is often loaded, it may be a little higher. There will be a recommended tire pressure requirement on the door seam of the car. It doesn't matter how much more or less tire pressure is, the relationship between fuel consumption, tire wear and tire pressure is actually minimal, as long as the tire pressure is basically balanced, don't exceed this.

The standard air pressure of different models and different tires is different, but the tire pressure used in most cars is relatively close, and many friends are used to controlling the air pressure of the tires. It is a good habit to check the tire pressure frequently, especially before running long distances and hitting high speeds.

This is even safer and more convenient for those trips computers that have tire pressure alarms, especially those that can also display tire pressure. As long as you pay attention to the meter prompt from time to time, it will be no problem.

However, the tire pressure of different types of car tires is very different, especially for the car, for example, the tire pressure of many trucks should be about 10 bar. In particular, it is best to install remote control testing equipment for large trucks with more tires, which is still worth the cost, to ensure the safety of their vehicles and goods, the tire pressure of large trucks is very high, once the tire burst, it will cause more serious damage to the surrounding vehicles and pedestrians.

Having said that, most people use sedans and SUVs, in fact, the air pressure of the tires is not completely fixed, but there is a range that can be adjusted. If you usually have a full load air pressure, you can hit it according to the upper limit, and the air pressure is slightly higher, and the driving resistance is relatively smaller, which is more fuel-efficient. If you basically use it yourself, and rarely pull heavy objects, you can beat the air pressure to a little higher than the specified lower limit, so that the comfort is better.

Different brands of tires have a lot of data labels on the side of the tire, including the maximum tire pressure, so the tire should not exceed this value.

My car is a short-axle Iveco, the air pressure of the tires is basically in, when there is no warranty, they are maintained in the 4S shop, their work specification is to control the front tire, the rear tire is controlled, which may be more convenient to carry and pull the goods, I have to say hello to them in advance every time, because my car is usually mostly empty run, so the front and rear hit, otherwise the urban area will be over the speed bump behind the old jump, uncomfortable. If I often run at high speeds or in good road conditions, I will also hit them all, and I can feel that the car is lighter and faster, and I save a little fuel.

For friends who often walk in the desert and play off-road, sometimes it is often necessary to lower the air pressure of the tires to increase the ground contact area of the tires and improve a certain passability. But go back to the paved road and hit the tire pressure back to normal as soon as possible.

Some brands of off-road vehicles can be modified or the original vehicle has an automatic tire inflation and deflation system, which can increase and decrease the tire pressure at any time during the journey, helping the vehicle to get the best driving and grip on different road surfaces.
