The Certification/Tire label or Tire and Loading Information label shows the correct inflation pressures for your tires when they're cold. "Cold" means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km). See Loading the Vehicle .
Notice: Don't let anyone tell you that underinflation or overinflation is all right. It's not. If your tires don't have enough air (underinflation), you can get the following:
• Too much flexing • Too much heat • Tire overloading • Bad wear • Bad handling • Bad fuel economy • Unusual wear • Bad handling • Rough ride • Needless damage from road hazards
When to Check
Check your tires once a month or more.
Also, check the tire pressure of the compact spare tire. It should be at 60 psi (420 kPa).
How to Check
Use a good quality pocket-type gage to check tire pressure. You can't tell if your tires are properly inflated simply by looking at them. Radial tires may look properly inflated even when they're underinflated.
Remove the valve cap from the tire valve stem. Press the tire gage firmly onto the valve to get a pressure measurement. If the cold tire inflation pressure is low, add air until you reach the recommended pressure on the Certification/Tire label or the Tire and Loading Information label.
If you overfill the tire, release air by pushing on the metal stem in the center of the tire valve. Recheck the tire pressure with the tire gage.
Be sure to put the valve caps back on the valve stems. They help prevent leaks by keeping out dirt and moisture.
