What Causes Consistently Low Tire Pressure in One Wheel?
1 Answers
The reasons for low tire pressure in a car tire are as follows: 1. Air leakage from the tire or valve stem, which requires inspection at a tire shop. 2. Wheel rim deformation, leading to reduced tire sealing performance. 3. Long-term overloading of the vehicle, causing uneven tire stress. 4. Thermal expansion and contraction; due to manufacturing variations in tires, thermal expansion and contraction may result in insufficient tire pressure. Below are the dangers of low tire pressure, remedies, and an explanation of the principle behind low tire pressure: The danger of low tire pressure lies in the increased risk of a blowout. It is advisable to observe all four wheels when exiting the vehicle; low air pressure can often be seen visually. If not visible, please visit an auto repair shop to measure the air pressure. When driving with low tire pressure, the tire's sidewall repeatedly folds and unfolds significantly during rotation, generating substantial heat. Additionally, the sidewall structure becomes more prone to fatigue, leading to broken cords and tire body rupture, which can cause a blowout.
