Why Is Tire Pressure Too Low?
3 Answers
Tire pressure being too low can be attributed to various reasons, including damage to the car tire or slow air leakage. When the tire pressure is too low, it can affect the vehicle's handling and increase fuel consumption, so it's important to replenish the tire pressure promptly. The specific reasons are as follows: 1. Car tire damage: When a car tire is damaged, it can lead to air leakage. If the tire is damaged, it must be repaired or replaced immediately to prevent safety hazards. There are several methods for repairing tires, including hot patching, mushroom nail patching, and rubber patching. If the tire is severely worn, it's best to replace it with a new one directly. After replacing a new tire, it's essential to perform a four-wheel alignment to prevent the vehicle from pulling to one side. 2. Slow air leakage in car tires: There are many causes for slow air leakage in car tires, including natural aging of the tire or the vehicle being parked for too long. When parking the car for an extended period, it should be placed on a flat and hard surface to prevent the tires from being deformed due to prolonged pressure. If the car is not used for a long time, it should be started once a week to ensure the engine oil and battery function properly.
Low tire pressure is actually quite common, and I've experienced it several times. The main reason is natural air leakage. Tires are not completely airtight, and air slowly escapes, especially if you don't check them for a long time. Temperature changes also have a big impact. In cold winters, the contraction is obvious, and you can feel the pressure is particularly low when driving in the morning. Another cause is punctures from nails or glass, which lead to air leaks—I once had a nail puncture that caused rapid pressure loss. Additionally, loose or aging valve caps can result in slow air leakage. For safety, I check the pressure with a tire gauge every time I refuel. The standard value is listed on the door pillar label, and maintaining even pressure can save fuel and prevent blowouts. When parking, I avoid rough roads to minimize extra wear and the risk of leaks.
In automotive maintenance experience, low tire pressure usually stems from valve issues or poor wheel rim sealing. Loose valve caps or worn valve cores can allow air to slowly seep out, leading to gradual pressure loss. Punctures from sharp objects are another major factor, potentially causing rapid air loss or even blowouts. Temperature also plays a significant role, with cold winter temperatures causing air contraction that worsens low-pressure conditions. I recommend regularly applying soapy water around the valve area; if bubbles appear, it indicates a leak. Additionally, improper wheel hub assembly can compromise sealing, resulting in continuous air loss. Checking tire pressure monthly can prevent these issues, extend tire lifespan, and reduce accidents.
