How much should the tire pressure of the Liberty ship be in each season

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.

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

Standard tires:

Reinforced tires:

Maximum air pressure: should not be greater than.

1) Seasonal factors:

a.Winter: Adjust the standard air pressure of automobile tires appropriately.

b.Summer: according to the lower limit of the standard air pressure of automobile tires.

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 punctures.

2) Loading load:

3) Tire pressure measurement environment:

a.Hot tires: The tire pressure of cool tires and hot tires is not the same, so pay attention to it when testing. The difference between the two is about.

b.Cold tyres: 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.

The front wheels do not exceed the rear wheels at the manufacturer's recommended tire pressure.

Generally normal tire pressures are between.

The tire pressure of the four tires is not the same, and the error is normal, and the five fingers are not necessarily long. However, it is not necessary to adjust the tire pressure monitoring, the error of tire pressure monitoring and the load of the car are different, which may cause temporary differences in tire pressure.

According to the provisions and requirements of the international GBT2978-2008 standard: standard tires:; Reinforced tires:Maximum air pressure: should not be greater than.

The tire pressure of the four tires is not the same, how much is the error normal?

The safest range for tire pressure in summer should be between. Generally speaking, the normal tire pressure is generally in the range of kilopascals, too high tire pressure will make the tire very hard, and too low tire pressure will lead to reduced handling and accelerated tire wear. In the summer, the overall tire pressure is about 10% lower than in other seasons.

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.

The tire pressure recommendation for the SUV's four tires in summer is more appropriate.

The tire pressure of standard tires is generally, but when driving in summer, the road surface temperature is as high as 50-70 degrees Celsius. In such a high temperature situation, the inside of the tire expands due to heat, and if the tire pressure is too high, the tire quality changes, and it is easy to burst the tire.

Therefore, it should be inflated according to the lower limit of the standard air pressure of automobile tires, and the air pressure can generally be about lower than the standard to avoid high-temperature punctures.

The landlord, I have seen it on Giti Weibo before, the tire pressure of the car is generally fully loaded, and the rear wheel is generally more than the rear wheel). And generally there will be a mark under the fuel tank cap of the car or under the driver's door, and you can adjust it a little more in winter.

If the vehicle is fully loaded, and there is a large amount of cargo in the trunk, the rear tire pressure can be appropriately increased to the four seasons in this range.

Standard tire pressure in winter.

Standard tire pressure in summer.

My front and rear tires are fuel-efficient, as long as it is not often at high speed, it is recommended to fill up, I have front tires and rear tires around me, which are normal and extremely fuel-efficient.

Generally speaking, the tire pressure is generally normal between to, not too high, it is easy to puncture if it is high.

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.

Now that the temperature is relatively low, the tire pressure in winter is generally kept between them!

Generally speaking, it is recommended that the tire pressure between the family car is more suitable.

The tire pressure is generally empty; Full load regardless of front and rear tires) Now 4S stores are generally set to the front and rear tires are the same), recommended: appropriate. Considering the principle of thermal expansion and cold contraction, the upper limit can be taken in winter.

It is best to check car tires 1-2 times a month, the tire pressure should not be too high in summer, it is easy to burst tires, and the tire pressure should not be too low in winter.

The normal tire pressure range for a typical car is between to. Four tires, consistent will do the trick.

Ordinary civilian radial vacuum tires, cold tire pressure four tires are kept at a more suitable level, and the road slippery in winter snow can be appropriately reduced.

Hello, the normal tire pressure of the car should be kept between it, and it is best to measure more accurately when the car is cold.

The normal tire pressure of the car is fine in between, and it is recommended that you measure the tire pressure after the tire dynamics.

The tire pressure recommendation for the car can be kept in between, and you can refer to it.

Hello, the tire pressure of the general car is recommended to be about high, not too high and not too low.

The normal tire pressure should be kept between the same and should not be too high or too low.

Hello, the tire pressure is recommended to be maintained for general family cars, and it is common in all seasons.

The tire pressure of the car should be normal between kilopascals, when the temperature is about 20 degrees, the tire pressure is generally maintained in kilopascals, but with the gradual increase in the temperature and the temperature of the road surface, high-speed or long-distance driving, the tire pressure is easy to rise, and it is easy to cause a puncture.

The tire pressure of a family car is generally kept between more appropriate, too high is easy to blow the tire, too low is not good for the tire.

The normal tire pressure range of the vehicle is suitable, but the temperature is high in summer, and it is recommended not to exceed it.

Hello, the tire pressure of the general car is relatively normal, not too high and not too low.

The normal tire pressure is maintained to the interval, and the tire pressure of the four tires is as consistent as possible.

If the tire pressure is in this range, it is better to keep the cold car in this range, and the safety and comfort are better.

The tire pressure of the car should be maintained between the to, too high or too low tire pressure will affect driving safety.

Hello, under normal circumstances, the tire pressure of the vehicle is on the mass

The so-called tire pressure, strictly speaking, refers to the pressure of the air inside the tire. Taking the human body as an analogy, 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 has a vital role in the performance and power of the car.

So how much is the appropriate "blood pressure" of the vehicle? According to the provisions and requirements of the international GBT2978-2008 standard: standard tires:

Reinforced tires:Maximum air pressure: should not be greater than.

However, this is only a uniform regulation, and in fact it has to do with many factors. For example, in the season, it can be adjusted higher in winter, and the lower limit of the standard air pressure in summer or lower to prevent the high temperature from causing a puncture when parked outside. In terms of the type and duration of the tire, the new tire can generally be higher than the standard, and the old tire is slightly lower than the standard.

As for the spare tire, because it is not used often, it can be higher than the standard when pumping, which can make up for the deflation phenomenon in the long-term placement, and will not cause the spare tire tire pressure to be too low to be used when the spare tire is needed.

As for the test, it is also very convenient, you only need to buy a mechanical tire pressure gauge (generally no more than 30 pieces), and develop the habit of regular testing.

If the owner is a novice, if you can't judge when to check, you can also buy built-in tire pressure monitoring equipment, which generally ranges from a few hundred yuan. Although it is a bit more expensive, it is fortunate that the tire pressure status can be monitored in real time.

If the tire pressure is insufficient, it will cause huge wear and tear on the tire, and it will be heavy when hitting the direction, and too high tire pressure can lead to a puncture. Therefore, it is recommended that car owners and friends check the tire pressure of the car once a month, and adjust the tire pressure in time once the tire pressure is found to be abnormal.

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 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 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.

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.

It is recommended to stay within the standard car tire pressure range: a.

barIt is a standard unit commonly used in tires and indicates how much force is applied on one square centimeterCattle (n cm)., exceptbarIn addition, we also use itMPA (megapascal).To indicate the tire pressure, for example, when we pump the car, the maintenance master will say how many kilograms, and the kilograms here also indicate the force per unit area.

1 bar = kilogram

Generally speaking, the tire pressure of the car should be kept between kilograms and kilograms to be more standard.

Therefore, supplementing the tire pressure within the standard tire pressure range should be determined according to the personal car habits and car environment.

For daily use in urban areas, the tire pressure can be kept within the standard range. Some riders feel that the kilogram is hard and the riding experience is poor, so you can slightly reduce the tire pressure to ensure a more comfortable riding experience, but not lower than the kilogram.

Car owners must remember: driving at high speeds, tire pressure should be higher than low. Although low tire pressure will not lead to a puncture, it will make the steering wheel feel heavier and easy to deviate from the direction, which is very harmful to high-speed driving, so before running at high speed, riders must develop the habit of checking the tire pressure first.

I used to raise the tire pressure to kilograms every time I got on the highway, anyway, the highway is very flat, it doesn't have much impact on the ride comfort, and the most important thing is to ensure the stability of the direction.

1. Low tire pressure and high fuel consumption

When the tire pressure is low, the contact area between each tire and the road surface will become larger, the friction coefficient will increase, and the force of the engine power acting on the ground will become larger, so the fuel consumption will be high;

2. High tire pressure and low fuel consumption

The tire pressure is high, the tire attachment area is slightly smaller, the friction coefficient is not so large, and the engine power loss is relatively reduced, so the fuel consumption will be reduced.

When the tire pressure is low, the adhesion area between the tire and the road surface becomes larger, and the structural factors of the tire determine that the shoulder will form an inward force, arching the tire crown upward, resulting in a large stress area on both sides of the shoulder and a relatively large wear; On the contrary, when the tire pressure is high, the wear on the tire crown is relatively large.

In general, the standard tire pressure is not only a guarantee of driving safety, but also a guarantee of tire life and fuel consumption. Therefore, all riders should develop good car habits.

As the New Year approaches, many people are ready to go home for the New Year, and a considerable number of people may choose to drive home. In order to be able to reach the hometown smoothly, an important job is to check the tire pressure of the car, because the tire is a part of the car in direct contact with the ground, as a wear part, the health of the tire is directly related to the safety and comfort of driving, and its importance is self-evident. Therefore, we need to understand the effect of tire pressure on tires and how much tire pressure is appropriate.

1. The influence of tire pressure on tires.

Normally, the part of the tire in contact with the ground (i.e. the tread) is evenly stressed and worn during daily driving, so when the tire pressure is too high or too low, what will be the effect on the wear of the tire?

The dangers of high tire pressure.

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

2. It causes the steering wheel to vibrate and deviate, which reduces the driving comfort and increases the vibration of the body, which indirectly affects the life of other parts.

3. Accelerate the local wear of the tread pattern of the tire, so that the life of the tire is reduced;

4. And reduce the rolling resistance. 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 bursts, resulting in a puncture.

The dangers of low tire pressure.

1. The friction coefficient with the road surface will increase, accelerating the loss and aging of tires, and increasing fuel consumption;

2. Cause the steering wheel to be very heavy, easy to deviate and other factors that are not conducive to driving safety;

3. 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 speed, it may cause a puncture;

Second, what kind of tire pressure is suitable for our car?

The point is: what is the most appropriate tire pressure for the car? In fact, there is no standard answer to this question, because the tire pressure standards are different for different models, the number of passengers and loads in actual driving, and even the tire pressure standards for the front and rear wheels of the same car are different. Therefore, according to different models and different driving conditions, we can choose the appropriate tire pressure according to the tire pressure label on our body, in fact, all our SAIC Volkswagen models are labeled with tire pressure labels for the reference of car owners and friends.

Tire pressure labels generally appear in two places:

Label next to the cab door (near the b-pillar).

On the inside of the fuel tank cover.

All in all, tire pressure is essential for the comfort and safety of our driving, and we must check it regularly (at least once a month) during our daily driving. And every long-distance trip should also be checked before the testimonial, if possible, it is best to monitor the tire pressure of the spare tire to ensure that our car tires are in the best condition, especially now, many car owners and friends want to drive home for the New Year, we must ensure safe driving, safe home, I wish you a happy New Year in advance.
