What Can Affect Tire Pressure in Hagerman, ID? How Much Should it Fluctuate?

Tire pressure changes are a common phenomenon that can have significant effects on vehicle performance, safety, and fuel efficiency. Understanding the reasons behind these pressure fluctuations is crucial for maintaining optimal driving conditions and prolonging the lifespan of your tires. Today, we at Highway 30 Garage would like to take the opportunity to discuss why tire pressure changes.

What Can Affect Tire Pressure?

Tire pressure, typically measured in pounds per square inch (psi) or kilopascals (kPa), refers to the amount of air within a tire. Proper tire pressure is essential for various reasons, including load-bearing capacity, stability, traction, and fuel efficiency. However, this pressure isn’t static; it changes for several reasons:
Temperature Fluctuations: One of the primary causes of tire pressure changes is temperature variation. As temperature increases, the air molecules inside the tire gain energy and move more vigorously, leading to an increase in pressure. Conversely, as temperatures drop, the molecules lose energy and move more slowly, resulting in decreased pressure. This phenomenon is described by the ideal gas law, where pressure is directly proportional to temperature.
Driving & Friction: While driving, tires experience friction with the road surface. This friction generates heat, causing the air inside the tires to warm up and expand. As a result, the tire pressure increases, which is why tire manufacturers recommend checking the pressure when the tires are cold, as heat generated during driving can lead to inaccurate readings.
Altitude Changes: Changes in altitude also affect tire pressure. At higher altitudes, the air pressure is lower than at sea level due to the thinner atmosphere. If you drive from a low-altitude area to a high-altitude one, the pressure inside your tires might increase slightly as the external air pressure decreases relative to the pressure inside the tire.
Permeation: Over time, air molecules can permeate through the rubber material of the tire, causing gradual pressure loss. While modern tires are designed with improved materials and construction techniques to minimize this effect, some pressure loss over time is inevitable.
Seasonal Changes: Seasonal temperature variations have a noticeable impact on tire pressure. As the weather transitions from cold winters to hot summers, tire pressure can fluctuate significantly. It’s recommended to monitor and adjust tire pressure seasonally to ensure optimal performance.
Leakage: Punctures or damage to the tire can lead to air leakage, causing a gradual decrease in tire pressure. Regularly inspecting your tires for any visible damage and promptly repairing or replacing them can help mitigate this issue.

Why is it Important to have Correct Tire Pressure?

Maintaining proper tire pressure is crucial for several reasons
Safety: Incorrect tire pressure can lead to reduced handling, compromised braking performance, and increased risk of accidents. Underinflated tires can overheat and potentially fail, while overinflated tires can reduce traction and stability.
Fuel Efficiency: Properly inflated tires offer less rolling resistance, improving fuel efficiency and reducing greenhouse gas emissions. According to the U.S. Department of Energy, underinflated tires can decrease fuel efficiency by around 0.2% for every 1 psi drop in pressure.
Tire Longevity: Correct tire pressure ensures even distribution of weight across the tire’s tread, leading to more uniform wear. This extends tire lifespan and helps you get the most out of your investment.
