Inflation - Cadillac 2003 DeVille Owner's Manual

Inflation
--
Tire Pressure
The Tire-Loading Information label, which is located or!
the rear edge of the driver's side rear 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 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 (1 521 Ibs) @ 300 kPa (44 psi) Max. Press.
For this example, you would set the
inflation press1n-e
for high-speed driving at 38 psi (265 kPa).
Nofice: 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

Check your tires once a month or more.
Don't forget your compact spare tire. It should be
at 60 psi (420 kPa).
