What Are the Causes of Insufficient Tire Pressure in Car Tires?

[OCaroline]

The causes of insufficient tire pressure in car tires are: 1. Leakage from the tire valve; 2. Deformation of the wheel hub leading to reduced tire sealing performance; 3. Long-term overloading of the vehicle causing uneven tire stress; 4. Manufacturing differences in tires may result in insufficient pressure due to thermal expansion and contraction. Solutions: 1. For tire leakage, inspect the cause and perform patching or replacement; 2. Replace the valve if it leaks or is aged; 3. Replace the wheel hub if it is deformed; 4. For overloading, the owner should change habits to ensure even tire stress; 5. For thermal expansion and contraction, consider inflating with nitrogen to minimize the effects.
