Inflation -- Tire Pressure; When To Check - GMC Envoy XL 2003 Owner's Manual

--
Inflation Tire Pressure
The Certificationflire label, which is on the driver's door
edge, above the door latch, 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).
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.
Also, check the tire pressure of the spare tire.
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.
