Tire pressure rises with increased temperature. Driving causes friction between the tire and the road, generating heat that warms the air inside the tires. This heat causes the air molecules to move more rapidly, increasing the pressure they exert on the tire walls. A typical increase might be between 3 and 6 psi, but this can vary based on ambient temperature, driving speed, and distance traveled.
Understanding the impact of driving on tire pressure is crucial for vehicle safety and performance. Properly inflated tires optimize fuel efficiency, handling, and braking distance, while also minimizing tire wear. Historically, awareness of this phenomenon evolved alongside the development of pneumatic tires and the understanding of the ideal gas law. Recognizing the relationship between temperature and pressure became essential for maximizing the benefits of this technology.
