The decrease in ambient temperature directly affects tire pressure. As temperatures drop, the air molecules within a tire contract, reducing the volume they occupy and consequently lowering the pressure. This phenomenon can lead to underinflation, which negatively impacts vehicle handling, fuel efficiency, and tire lifespan.
Maintaining proper tire pressure is essential for safe and efficient vehicle operation. Underinflated tires increase rolling resistance, requiring more energy to maintain speed and thus reducing fuel economy. Furthermore, they compromise handling and braking performance, potentially leading to accidents. Historically, understanding the relationship between temperature and tire pressure has been crucial for developing safer and more efficient vehicles. Modern vehicles often incorporate tire pressure monitoring systems (TPMS) to alert drivers to low pressure situations, reflecting the ongoing significance of this issue.
