However, there’s a common myth that cold weather can lower tire pressure. But what’s the truth behind this claim, and how can you ensure your tires are always properly inflated?
The Effects of Temperature on Tire Pressure
Let’s start with the basics. Tire pressure is determined by the amount of air inside the tire, which is measured in pounds per square inch (PSI). According to the United States Environmental Protection Agency (EPA), tire pressure can be affected by temperature changes. Here’s why:
| Temperature | Pressure Change |
| — | — |
| 0°F (-18°C) | -0.1-0.2 PSI |
| 32°F (0°C) | 0 PSI (standard) |
| 100°F (38°C) | +0.2-0.3 PSI |
As you can see, temperature changes can impact tire pressure, but the effect is relatively small. However, what’s worth noting is that tire pressure tends to decrease with lower temperatures and increase with higher temperatures.
Understanding the Science Behind Tire Pressure and Temperature
To understand why tire pressure changes with temperature, let’s look at the composition of tires. Tires are made up of various materials, including rubber, which expands and contracts with temperature changes. When the temperature drops, the rubber inside the tire becomes less dense, causing the air inside to expand slightly. This expansion can lead to a decrease in tire pressure.
On the other hand, when the temperature rises, the rubber inside the tire becomes more dense, causing the air inside to contract slightly. This contraction can lead to an increase in tire pressure.
Case Study: The Effect of Cold Weather on Tire Pressure
Let’s look at a real-world example to illustrate the effects of cold weather on tire pressure. A study conducted by the National Highway Traffic Safety Administration (NHTSA) found that tire pressure can drop by as much as 1-2 PSI in extremely cold temperatures.
Here’s a breakdown of the study’s findings:
Original tire pressure: 35 PSI
As you can see, the temperature drop had a significant impact on tire pressure, resulting in a 6-9% decrease.
Practical Tips for Maintaining Proper Tire Pressure in Cold Weather
While the effects of cold weather on tire pressure may seem small, it’s essential to take steps to ensure your tires are always properly inflated. Here are some practical tips to help you maintain proper tire pressure in cold weather:
Check your tire pressure regularly: Use a reliable tire pressure gauge to check your tire pressure at least once a month, and before long trips.
