What is the appropriate tire pressure for the four wheels of a car?

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.

Check the tire pressure frequently to ensure safety

1. Observe the condition of the tires before traveling. Radial tires - that is, commonly known as low-pressure tires, as long as the flatness is not too low, it feels very elastic when pedaled, and it is normal if it is not soft.

High-pressure tire - it is a bias tire with an inner tube, and the shoulder part of the tire is not prominent from the front, commonly known as it"No cheek swelling"From the side, the contact with the ground is about the same as the usual area, which is normal.

2. Pay attention to the sound of the friction between the tires and the ground during driving, feel the buffer force when the road is not very flat, and feel whether the acceleration when refueling has changed compared with usual, these are all ordinary accumulated experience.

Hello, the tire pressure of the four wheels of the car needs to be between.

The tire pressure of the 4 wheels is allowed to be different.

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. Generally, the pressure of the two tires in the back will be a little higher than that in the front.

The standard tire pressure of the vehicle is about the enhanced tire: in winter, the standard air pressure of the automobile tire is appropriately adjusted according to the principle, and the lower limit of the standard air pressure of the automobile tire is about in summer. Both high and low tire pressure can shorten the life of your tire.

Tire pressure precautions:

When driving in the summer, you can lower the air pressure of the tires. Because of the hot summer temperature, the car is driving on the hot road, and this heat will be transferred to the tires, causing the gas in the tires to expand by heating, making the tire pressure higher. On the contrary, you can raise the tire pressure a little bit in winter, because the volume of the gas will become smaller when it is cold, and the tire pressure will naturally decrease.

In addition, when driving on muddy dirt roads or loose sandy ground, the tire pressure can be appropriately reduced, because this can improve the adhesion of the tires and improve the passability of the vehicle. Therefore, many high-end off-road vehicles have the function of automatically adjusting the tire pressure.

The tire pressure of the 4 wheels is allowed to differ within the range, but it is not necessary to adjust it if it is exceeded, and the error of tire pressure monitoring and the load of the car are different, which may cause the tire pressure to be temporarily different. Generally, the pressure of the two tires in the back will be a little higher than that in the front.

Notes:The standard tire pressure of the vehicle is about the enhanced tire: in winter, the standard air pressure of the automobile tire is appropriately adjusted according to the principle, and the lower limit of the standard air pressure of the automobile tire is about in summer.

Both high and low tire pressure can shorten the life of your 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 of the four tires of the car cannot be the same all the time, and generally the pressure of the first two tires will be a little higher than that of the back, and the difference is normal.

If the tire pressure difference between the four tires is too large, the life of the tire itself and fuel consumption will be affected, because the tire pressure of the four tires is not the same, which will cause abnormal tire wear, and the tire pressure is too high, which will concentrate the weight of the body on the tread center, resulting in rapid wear of the tread center. The tire pressure is too low, which is easy to make the tire contact area uneven, increase wear, increase rolling resistance, and increase fuel consumption.

Tire pressure precautions:

Before inflating, the dirt and dust on the valve should be wiped clean. When inflating, try not to loosen or take out the valve core, and forcibly inflate by increasing the air pressure to prevent the valve screw from tripping and leaking. After the inflation is completed, it should be dipped in water and applied to the valve to check for air leakage, so that the valve core can be tightened or replaced as appropriate.

After inflating, the valve cap should also be fully fitted to prevent sediment from entering the valve.

Always observe the changes of the air pressure gauge that comes with the inflator pump, inflate in strict accordance with the standard value of tire pressure, and relieve pressure when the inflation is too much. Fengjinba's on-board pump T800 is not only equipped with a light and a pressure gauge, which is fast to pump up, easy to carry and store, and has a tire pressure gauge function to facilitate the detection of tire pressure at any time, and can be replenished in time when the tire pressure is insufficient.

The tire pressure of the general family car is, which is converted to 2, which is 2 kg to kg as the car mechanic usually says.

If the tire pressure is too high, although it can reduce the friction resistance between the tire and the road surface, and play a role in fuel saving, the disadvantage is that it will reduce the shock absorption effect of the tire, and the vibration of the body with the uneven ground will increase during driving, thereby reducing the comfort of the ride. If you drive for a long time in the summer, there is also a risk of "puncture" if the tires overheat.

The tire pressure is low, so that the tread contact with the ground area increases, the friction resistance increases, the fuel consumption will increase, if the tire pressure is too low, it will also wear and squeeze the side of the tire, reducing the service life of the tire.

The car engine adopts the front, that is, arranged in the front of the car, so the load bearing of the front part of the body is larger, so the tire pressure of the front wheel is generally slightly lower than that of the rear wheel. At the same time, according to the difference between the ambient temperature in winter and summer, the pressure of the tire should also be adjusted appropriately, roughly as follows, in summer, the front tire pressure is generally about kilograms, and the rear tire pressure is about kilograms to kilograms.

In winter, the front tire pressure is generally around kilograms, and the rear tire pressure is about kilograms to kilograms.

Of course, now mid-to-high-end cars are generally equipped with a tire pressure monitoring system, which can be immediately warned once the tire pressure is abnormal, which is safer and more reliable.

Tires, as a ring-shaped elastic rubber product that supports the body, can ensure the driving performance of the car. It is also very important to maintain normal tire pressure, as too high or too low tire pressure will endanger driving safety. So how much is the difference in tire pressure between the four tires considered normal?

Tire pressure 1 Generally speaking, the tire pressure of the four tires of the car cannot be the same all the time, usually the tire pressure of the front two tires is relatively high, but the tire pressure of the front and rear tires will not be too different, generally within the range. 2. If you find that the tire pressure difference is very large, you must immediately take relevant measures to adjust the tire pressure. Because if the tire pressure deviation is too large, the driving resistance of each tire will be different.

The tire pressure on both sides of the coaxial tire is different, which will cause the car to deviate when driving, which will affect the safety of driving. 3 According to the position of the engine, the car can be divided into front-wheel drive and rear-wheel drive vehicles. The engine of a front-wheel drive car is placed in front of the car, and the front wheels are responsible for steering and driving at the same time.

A rear-wheel drive car, on the other hand, is the opposite of a front-wheel drive car, with the engine placed at the back of the car, the front wheels responsible for steering, and the rear wheels responsible for driving. In terms of tire pressure, the front tire pressure is higher in front-wheel drive vehicles, while the rear tire pressure is higher in rear-wheel drive vehicles. Due to various factors, the tire pressure of the four tires will not always be the same, and there will be a certain difference.

However, this difference is safely limited, and the difference between the tire pressure of the four tires should be kept within the range.

Tire pressure is normal, generally your car with tire pressure detection on the line, high tire pressure will alarm, I hope to help your reply.

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.

<> "Tire pressure is very important for cars, and timely monitoring of tire pressure can keep the car in a relatively safe condition. So how much is the difference between the four tires of the car?

Usually the difference in tire pressure between the four tires of the car is normal, but it can not be exceeded, if the tire pressure value exceeds, the owner needs to adjust it in time.

The error of tire pressure monitoring and the difference in the load of the car may make the tire bench pressure temporarily inconsistent; If the car exceeds this value under normal conditions without monitoring errors and load conditions, it needs to be repaired.

The uneven tire pressure on the left and right sides will make the braking effect of the car worse, and the control will also be out of control, resulting in difficult or heavy steering, and damaging the service life of the tire, so the owner must pay more attention to the tire pressure.

The owner reads the tire pressure monitoring socks of the vehicle and finds that the tire pressure of the four tires of the car is not the same, I don't know if it will have an impact, so how much is the pressure difference between the four tires in the normal range?

Under normal circumstances, there is a certain difference in the tire pressure of the car tires, and the tire pressure of the four tires cannot be consistent, but the maximum difference in the tire pressure is not allowed to exceed, and it is abnormal to exceed. Generally, the tire pressure of the front wheel of the car is slightly higher than that of the rear wheel. The normal range of tire pressure of car tires is between, the tire pressure range is normal, and the comfort and safety of the car are also the best.

The owner needs to adjust the tire pressure of the four tires according to the data recommended by the manufacturer, and the recommended tire pressure can be seen in the vehicle's manual or engine cover, or go to the 4S store to check the tire pressure, if there is a problem with the tire pressure, the owner needs to adjust it in time. Long-term tire pressure inconsistency will lead to excessive wear of tires with low tire pressure, reduce the service life of tires, and increase the cost of replacing tires.
