. Why does my Changan Oshan X7 show inconsistent tire pressure readings between all four tires?

I regularly check tire pressure using the in-car TPMS, but the readings are often uneven, even when I fill all tires to the same PSI. One tire might be 32 PSI while another is 36. Is this a sensor issue o r a problem with the tires themselves?

Inconsistent tire pressure readings between the tires can happen due to several reasons:

Temperature differences between each tire e.g., tires exposed to sunlight heat up more

TPMS Tire Pressure Monitoring System calibration may be slightly off it’s normal to have ±1–2 PSI difference

Manual air filling at local fuel stations is often inaccurate due to faulty gauges

Slight air leakage from one o r more valves o r tires

To fix this:

Always check tire pressure when the tires are cold preferably early morning

Use a digital tire pressure gauge for accuracy

If differences are persistent o r increasing, have your TPMS sensors checked by a mechanic
