Inflation -- Tire Pressure
The Tire
-
Loading Information label, which is located on
the rear edge of the driver’s door, 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).
If you’ll be driving at speeds higher than 100 mph 
(160 km/h) where it is legal, raise the cold inflation
pressure of each tire to 38 psi (260 kPa) for tire 
size P225/55R16 and to 39 psi (270 kPa) for tire 
size 235/45R17. When you end this very high

speed
driving, reduce the cold inflation pressures to those
listed on the Tire

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.
