Temperature differences during sea transport can easily trigger the tire pressure warning. After inflating the tires to the standard pressure (usually 2.5 Bar), most vehicles will automatically clear the warning after driving a few kilometers; some models require manually clicking "Tire Pressure Reset" in the "Vehicle Settings" on the central screen.

We cannot open each tire to inspect the inside. However, if a visual inspection reveals severe creases on the tire sidewall, it indicates that the run-flat tire has been driven for a long time at zero pressure, damaging its internal structure. We would recommend replacing it before shipping.

We use two steps: 1. Insert a medical-grade endoscope through the spark plug hole to visually inspect cylinder wall scratches and carbon buildup on the piston top; 2. Extract an engine oil sample to check for large metal debris or emulsification (caused by coolant leakage).
