Does Tire Pressure Automatically Decrease in Winter?

[LorenzoMarie]

Tire pressure does automatically decrease in winter, which is caused by the thermal expansion and contraction of gases. Proper inflation is recommended: If the low-temperature period is not prolonged, there's no need for inflation as the tire pressure will recover when temperatures rise. For extended cold periods, drivers may inflate tires moderately but avoid over-inflation to prevent excessive tire pressure. Tire pressure monitoring system anomalies: Another scenario is sudden low-pressure warnings during driving when actual measurements show normal pressure. This occurs because some vehicles' monitoring systems may malfunction in cold weather, causing false alarms. As long as manual checks confirm normal pressure, there's no significant issue.
