What should I do when the wheel tire pressure is abnormal?

Tires are an important part of a car, and tire pressure has a great impact on tires. If the tire pressure is high, there will be an increased risk of tire blowouts and accelerated tire wear. If the tire pressure is low, fuel consumption and braking distance will increase. So we need to make sure that our tire pressure is within the normal range. When the tire pressure is within the abnormal range, it should be repaired as soon as possible. Before repairing, we need to know what causes the tire pressure to be too high or too low.

Causes of Tire Pressure Problems

Why is the tire pressure low?

1. Natural leakage: The rubber material of the car tire is not completely sealed and may leak air naturally.

2. Temperature changes: When the temperature drops, the air pressure in the tire will decrease accordingly.

3. Tire damage: The tire will be damaged by puncture, impact or wear from external objects, resulting in air leakage.

4. Valve problem: The tire valve is loose, aged or damaged.

5. Hub seal problem: The seal between the hub and the tire is poor, resulting in air leakage.

6. Tire aging: After long-term use or long-term parking, the tire may become hard or cracked due to aging.

7. Tire pressure monitoring system failure: If the car is equipped with a tire pressure monitoring system, system failure or sensor damage may also cause false indications of low tire pressure.

Why is the tire pressure high?

1. Temperature changes: Rising temperatures cause the air pressure inside the tire to rise. This is because as the temperature rises, the air molecules inside the tire diffuse and move faster, which in turn causes the tire pressure to rise.

2. Driving for too long: During the driving process of the vehicle, the friction between the tire and the ground generates heat, causing the temperature inside the tire to rise and the gas to expand, which increases the tire pressure by 2.

3. Tire condition: The tire pressure of new tires is usually higher than that of old tires because the rubber of new tires is harder and less elastic. In addition, if the tire is severely worn or damaged, it may also cause the tire pressure to rise.

4. Loading load: The more cargo or passengers the vehicle is loaded with, the heavier the load on the tire, and the tire pressure may increase. To ensure the safety performance of the tire, it is recommended to adjust the tire pressure according to the vehicle's load.

5. Tire pressure monitoring system failure: If the vehicle's tire pressure monitoring system fails, it may display incorrect tire pressure information, including showing that the tire pressure is too high.

6. Spare tire use: The spare tire may have a higher pressure than normal because it is not often used. In order to ensure that the spare tire can be used normally in an emergency, it is recommended to check the spare tire pressure regularly and adjust it as needed.

In summary, high tire pressure may be the result of a combination of factors. In order to ensure driving safety, it is recommended to check the tire pressure regularly and adjust it according to the actual situation. At the same time, if the tire pressure is found to be abnormal, the cause should be found and repaired in time.

How to solve the problem of abnormal tire pressure?

How to solve low tire pressure?

Low tire pressure may affect the handling and safety of the vehicle, and may even cause tire damage. When the problem of low tire pressure occurs, we should check and solve the problem in time. So how can we solve it?

1. Check the tire condition: First check whether the tire has obvious damage, such as nails, cuts or wear. Because tire damage can cause tire leakage, resulting in low tire pressure. If damage is found, the tire should be replaced in time.

2. Inflate to standard pressure: Use the tire air pump or go to a nearby gas station or repair shop to inflate the tire to the standard pressure recommended by the vehicle manufacturer. The standard pressure can usually be found in the vehicle owner's manual, door frame or inside the fuel tank cap.

3. Check the valve: Make sure the valve is not damaged or loose, and the valve cap is tightened. Damaged or loose valves may leak, resulting in low air pressure.

4. Regular inspection and maintenance: Check tire pressure regularly, especially after seasonal changes or after a long period of non-use of the vehicle. Changes in temperature will affect tire pressure. The principle of thermal expansion and contraction will cause tire pressure to be lower in winter and higher in summer.

5. Tire balancing and four-wheel alignment: If the tire pressure is often low and the tire is abnormally worn, you may need to perform tire balancing and four-wheel alignment inspections.

6. Replace tires: If the tires are severely aged, cracked or bulged, they should be replaced with new tires in time. Aged tires have poor sealing and are prone to reduced air pressure.

The above methods can effectively solve the problem of low tire pressure and ensure the safety and normal operation of the vehicle.

How to solve the problem of high tire pressure?

Excessive tire pressure may affect the handling and stability of the vehicle, and even increase the risk of tire blowout. So how should we solve it?

1. Check tire pressure regularly: It is a good habit for car owners to check tire pressure regularly. You can find the recommended tire pressure range in the vehicle manual or on the side of the tire, and use a professional tire pressure gauge to measure it. If the tire pressure is found to be too high, it can be adjusted appropriately to the recommended range.

2. Deflation operation: If there is a pointer tire pressure gauge, you can unscrew the cover of the tire valve, find the center core of the valve mouth and press it lightly, then press the deflated valve while comparing it with the tire pressure gauge, and observe the numbers on the gauge until the tire pressure returns to normal. If there is no special deflation valve, you can use a valve core wrench to deflate, or use a thin pointed object to push the valve core and then slowly deflate the air. This method requires careful operation to avoid damaging the valve core.

3. Pay attention to driving behavior: Avoid driving for a long time during high temperature periods to reduce the degree of heat expansion of the tire. At the same time, avoid violent driving behaviors such as sudden acceleration and sudden braking to reduce friction and wear between the tire and the ground.

4. Professional maintenance: If the tire pressure is often too high, it is recommended to go to a professional tire repair shop for inspection to ensure that there are no other potential problems with the tire and rim.

The above methods can effectively solve the problem of excessive tire pressure and ensure driving safety.

What are some commonly used tools?

1. Tire pressure gauge: A tire pressure gauge is a tool for measuring the tire pressure of a vehicle. There are three types of tire pressure gauges: pen-type tire pressure gauges, mechanical pointer tire pressure gauges, and electronic digital tire pressure gauges. Among them, the digital tire pressure gauge has the most accurate value and is the most convenient to use. The tire pressure gauge is simple to use and easy to operate, and you can quickly know the tire pressure.

2. Tire air pump, also known as an air pump or inflator, is a tool used to inflate inflatable equipment such as tires, balls, and inflatable toys. It works by running an internal motor, using the principle of atmospheric pressure to compress the gas and inject it into the object that needs to be inflated. There are many types of tire air pumps, and you can use the corresponding air pump according to your vehicle model and needs.
