How long is a tire pressure check considered valid?

A tire pressure check is considered valid for 24 hours due to the nature of how tire pressure can fluctuate based on temperature changes, driving habits, and environmental conditions. Factors such as temperature can cause air inside the tire to expand or contract, leading to variations in pressure.

Once a tire pressure check is completed, the assessment is dependent on stable conditions. If the vehicle is driven or if there are significant changes in temperature, the pressure readings could change, thus necessitating a recheck. The 24-hour window offers a reasonable timeframe in which the tire pressure is likely to remain stable provided no significant changes occur in those conditions, making it practical for regular monitoring.
