Inflation - Tire Pressure
The 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 Your Vehicle on page 4-49, for the location
of your vehicle’s tire and loading information label.
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. Check the tire’s
inflation pressure when the tires are cold. Cold means
your vehicle has been sitting for at least three hours or
driven no more than 1 mile (1.6 km).
