🌍 Real-World Use Case
I took this RV TPMS on a 400-mile trip through mountain passes. Temperatures dropped overnight; by morning one rear tire PSI had fallen ~8 PSI. Alert went off, I inflated at the next stop.
Later, while driving downhill during a thunderstorm, another tire got hot due to heavy braking. The “high temp” alert gave me a chance to cool down and adjust driving style.
