Tire pressure is determined by the amount of air inside the tire, which is measured in pounds per square inch (PSI). The pressure within a tire supports the weight of the vehicle and its cargo, and provides the necessary traction for driving. The science behind tire pressure involves understanding how air density changes with temperature and how these changes affect tire performance.

When the temperature drops, the air inside the tire becomes denser, causing the pressure to decrease. This is due to the ideal gas law, which states that the pressure of a gas is directly proportional to its temperature when volume is constant. In practical terms, this means that for every 10 degrees Fahrenheit decrease in temperature, tire pressure drops by approximately 1 PSI.

This decrease in pressure can have significant effects on the tire's ability to perform. Lower tire pressure can increase the rolling resistance of the tire, leading to higher fuel consumption and reduced efficiency. It can also cause the tire to flex more, which can lead to increased heat buildup and potential tire failure. Understanding the science behind tire pressure is essential for maintaining safe and efficient driving conditions, especially during the winter months.
