Low temperatures can decrease tire pressure, sometimes significantly enough to cause underinflation, which can lead to tire damage or failure. This pressure drop results from the air inside the tire contracting in response to the colder ambient temperature. A tire appearing underinflated on a cold morning may return to a seemingly normal pressure as the day warms and the air expands. However, it’s crucial to verify the pressure with a gauge, as the tire could still be underinflated even after some warming.
Understanding the relationship between temperature and tire pressure is essential for vehicle safety and optimal tire lifespan. Regular pressure checks, especially during colder months, can prevent potential hazards like blowouts, poor handling, and reduced fuel efficiency. Historically, this phenomenon has been a consistent challenge for drivers, particularly before the advent of readily available tire pressure monitoring systems (TPMS). These systems now offer a more proactive approach to managing tire pressure fluctuations.
