Understanding Tire Pressure

Importance of Correct Tire Pressure

Improves fuel efficiency by up to 3%
Extends tire life by reducing uneven wear
Enhances safety and handling precision
Provides a smoother ride with less road noise
Reduces the risk of blowouts and flat tires

When to Check Tire Pressure

At least once a month
Before long trips or heavy loads
When tires are cold (before driving)
When outdoor temperatures change significantly
After hitting potholes or curbs

Finding Your Recommended Pressure

Your vehicle's recommended tire pressure can be found in:

Driver's side door jamb sticker
Owner's manual
Inside fuel door
Glove box

Note: The pressure listed on the tire sidewall is the maximum pressure, not the recommended pressure for your vehicle.

Tire Pressure Units

PSI:

Standard in the US. 1 PSI = force of 1 pound on 1 square inch.

Bar:

Common in Europe. 1 bar ≈ 14.5038 PSI, close to atmospheric pressure.

kPa:

SI unit of pressure. 100 kPa = 1 bar, 1 kPa ≈ 0.145038 PSI.

kg/cm²:

Used in some regions. 1 kg/cm² ≈ 14.2233 PSI, slightly less than 1 bar.

Temperature Effects

Tire pressure changes approximately 1 PSI for every 10°F (5.6°C) change in temperature.

Cold weather ❄️Hot weather 🔥

Lower pressureHigher pressure

Tires lose pressure naturally over time due to permeation through the rubber. Check pressure regularly, especially after seasonal temperature changes.
