Inflation - Tire Pressure - Cadillac 2004 DeVille Owner's Manual

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 4-33 for more
information on the Tire and Loading Information label.
If you'll be driving at high speeds (e.g., speeds of
100 mph (160 km/h) or higher), where it is legal, set the
cold inflation pressure to the maximum inflation
pressure shown on the tire sidewall, or to 38 psi
(265 kPa), whichever is lower. See the example below.
When you end this high-speed driving, return to the
cold inflation pressure shown on the Tire-Loading
Information label.
Example:
You'll find maximum load and inflation pressure molded
on the tire's sidewall, in small letters, near the rim
flange. It will read something like this: Maximum load
690 kg (1521 lbs) 300 kPa (44 psi) Max. Press.
For this example, you would set the inflation pressure
for high-speed driving at 38 psi (265 kPa).

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
