Why Do Tires Lose Air Pressure Over Time?
Tires lose air pressure over time due to a combination of natural and environmental factors. This gradual loss can lead to underinflation, affecting vehicle performance and safety.
According to the National Highway Traffic Safety Administration (NHTSA), a major organization focused on vehicle safety, tires can lose one pound per square inch (psi) of pressure each month simply from natural permeation of air through the rubber.
Several underlying reasons explain why tires lose air pressure. First, air can escape through tiny pores in the tire material. Tires are made from multiple layers, including rubber and other materials, which are not completely airtight. Second, temperature changes significantly impact tire pressure. When temperatures drop, the air inside the tire contracts, reducing pressure, while heat causes expansion, increasing it. Third, damage like punctures or valve failures can lead to sudden air loss.
These phenomena can be classified under two technical terms: permeation and temperature fluctuation. Permeation refers to the gradual movement of air molecules through the rubber. Temperature fluctuation indicates the variations in ambient temperature that can either expand or contract the air within the tire.
Detailed explanations of these mechanisms show how they affect tire pressure. As air molecules move through the tire’s rubber, they slowly escape into the atmosphere. This occurs irrespective of how well the tire is sealed. Meanwhile, a decline in temperature, especially in winter months, can decrease tire inflation levels by approximately 1 psi for every 10°F drop in temperature. Additionally, physical damage, such as running over sharp objects or hitting potholes, can create punctures where air escapes more rapidly.
Specific conditions and actions significantly contribute to the loss of tire air pressure. Common situations include:
- Extreme temperatures: Cold winters or hot summers can change tire pressure significantly.
- Tire wear: Older tires with decreased tread may have a higher rate of air loss.
- Improper installation: Incorrect mounting of tires can lead to leaks.
