According to the National Highway Traffic Safety Administration (NHTSA), maintaining recommended tire pressure can improve vehicle handling and control. They state that under-inflated tires can lead to blowouts and poor traction, increasing the risk of accidents.
Several underlying factors contribute to the need for regular tire pressure checks. First, temperature changes can cause air to expand or contract within the tire. For example, tires can lose about 1 psi (pound per square inch) of pressure for every 10°F (5.5°C) decrease in temperature. Second, normal wear and tear can lead to gradual air loss. Finally, improperly mounted tires or damage can also result in slow leaks.
Tire pressure measurements are expressed in psi (pounds per square inch), which quantifies the amount of air in the tire. An under-inflated tire contains less air than recommended, while an over-inflated tire contains too much. Proper pressure is crucial for maintaining the correct contact surface between the tire and the road.
The mechanisms involved in tire pressure regulation include pressure loss through permeation and punctures. Permeation occurs when gas molecules gradually seep through the tire’s rubber material over time. For example, a tire might lose 1-2 psi per month due to this process alone. Punctures occur from debris on the road, leading to immediate pressure loss.
Specific actions can contribute to improper tire pressure. For instance, frequently driving over potholes can damage the tire and cause air leaks.
