Temperature significantly impacts tire pressure. Lower temperatures cause the air inside tires to contract, leading to a noticeable decrease in pressure. For example, a temperature drop of 10 degrees Fahrenheit can reduce tire pressure by approximately 1-2 psi.
Maintaining correct tire pressure is crucial for vehicle safety, fuel efficiency, and tire longevity. Underinflated tires increase rolling resistance, which reduces fuel economy and increases wear and tear. More importantly, underinflation compromises handling and braking, increasing the risk of accidents. Historically, this phenomenon has been a persistent concern for drivers, especially during seasonal transitions. Understanding the relationship between temperature and tire pressure has become increasingly important with the development of advanced tire pressure monitoring systems (TPMS) in modern vehicles.
