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

If your tires have too much air (overinflation), you
can get the following:

Unusual wear

Bad handling

Rough ride

Needless damage from road hazards

When to Check

Check your tires once a month or more.

Don’t forget your 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.

Be sure to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt and moisture.

Check Tire Pressure System

If your vehicle has the check tire pressure system, it
can alert you to a large change in the pressure of one
tire. The system won’t alert you before you drive
that a tire is low or flat. You must begin driving before
the system will work properly.

The CHECK TIRE PRESSURE message will appear on
the Driver Information Center (DIC) if pressure
difference (low pressure) is detected in one tire. The
check tire pressure system may not alert you if:

more than one tire is low,

the vehicle is moving faster than 65 mph (105 km/h),

the system is not yet calibrated,

the tire treadwear is uneven,

the compact spare tire is installed,

tire chains are being used, or

the vehicle is being driven on a rough or
frozen road.
