Can temperature swings between day and night cause false TPMS Tire Pressure Monitoring System warnings on Model 2?

In Pakistani cities, daytime temperatures can be very high while nighttime temperatures significantly. Since tire pressure s when it cools and rises when it heats, could these fluctuations trigger low‑ o r high‑pressure warnings even when there is no leak? How reliable would the Model 2’s TPMS be in such changing conditions, and what should drivers do to avoid constant warning lights?

Yes — when the temperature s overnight or in the evening, the air in the tires contracts, reducing pressure.

TPMS Tire Pressure Monitoring System is designed to alert you when pressure goes outside a certain “safe” range. If your tire pressure s simply because of temperature, TPMS may trigger a low-pressure warning even though theres no leak. Users on forums have reported exactly this behavior:

“When it gets cold the pressure will go down … If it warms up and is too high you will get the warning as well.”
Reddit

Also, when you drive, tires heat up, so pressure rises — but TPMS might exaggerate this as a “high-pressure” event if the thresholds are tight.

What to do:

Always reset o r recheck your TPMS baseline when tires are cold e.g., in the morning.

Use a good-quality manual pressure gauge to verify TPMS readings, especially after big temperature swings.

If warnings are frequent but pressures seem correct when cold, consider whether your TPMS thresholds or system behavior need adjustment / calibration.
