Notice: Do not let anyone tell you that under-inflation or over-inflation is all right. It is not. If your tires do not have enough air (under-inflation), you can get the following:

A Tire and Loading Information Label located on the driver's door opening sill below the door striker (coupe) or rear edge of the driver's door (sedan and wagon), shows the correct inflation pressure for your tires when they're cold. "Cold" means your car has been sitting for at least three hours or driven no more than 1 mile (1.6 km). If you have to check tires when they're not cold, add 4 psi (28 kPa) to the number on the sticker.

Check your tires once a month or more. Don't forget to check the compact spare tire. it should be at 60 psi (420 kPa). Remember to check tire pressure when the tires are cold.

Use a good quality 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.

Never release air from a hot tire in order to reach the recommended cold tire pressure. Normal driving causes tires to run hotter and air pressure to increase. If you release air when your tires are hot, you may dangerously underinflate your tires.

If your tires have valve caps, be sure to put them back on the valve stems. They help prevent leaks by keeping out dirt and moisture.
