- Altitude changes
- Load weight
- Driving speed
- Road surface conditions
Understanding these conditions can help maintain optimal tire pressure. Proper tire pressure ensures better vehicle handling and improves fuel efficiency.
-
Temperature Fluctuations: Temperature fluctuations affect tire pressure due to the general principle that gases expand when heated and contract when cooled. As temperatures rise, tire pressure can increase by about 1 PSI for every 10°F increase according to the Tire Industry Association. Conversely, during cold weather, tire pressure can drop. For example, if the temperature drops from 70°F to 30°F, the tire pressure can decrease by nearly 5 PSI. This fluctuation can lead to under-inflated tires, causing reduced traction and increased wear.
-
Altitude Changes: Altitude changes impact tire pressure because of the decrease in external air pressure at higher elevations. The general rule is that tire pressure decreases approximately 1 PSI for every 1,000 feet of elevation gain. For instance, if you drive from sea level to a mountain pass at 5,000 feet without adjusting your tire pressure, your tires can lose 5 PSI. This can affect vehicle handling and performance.
