If you put things inside your vehicle-
like suitcases, tools, packages, or
anything else-they will go as fast as
’ the vehicle goes. If you have to stop or
turn quicltly,
or. if there is a crash,
they’ll keep going.
Tires
We don’t make tires. Your new vehicle
comes with high quality tires made by a
leading tire manufacturer. These tires
are warranted by the tire manufacturers
and their warranties are delivered with
every new Oldsmobile. If your spare tire
is a different brand than your road tires,
you will have a tire warranty folder from
each of these manufacturers.

Inflation - Tire Pressure
The Tire-Loading Information label
which is on the inside of the trunk lid
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 a mile.
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:
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:
Unusual wear
Bad handling
Rough ride
Needless damage from road
hazards.
When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It
should be at
60 psi (420 1tPa).

How to Check
Use a good quality pocket-type gage to
check tire pressure. Simply looking at
the tires will not tell you the pressure,
especially if you have radial tires
-
which may look properly inflated even if
they’re underinflated.
If your tires have valve caps, be sure to
put them back on. They help prevent
leaks by keeping out dirt and moisture.
~
Tire lnspection and Rotation
To make your tires last longer, have
them inspected and rotated at the
mileages recommended in the
Maintenance Schedule.
See Scheduled
Maintenance Services
in the Index.
Use this rotation pattern.
After the tires have been rotated, adjust
the front and rear inflation pressure as
shown
on the Tire-Loading Information
label. Make certain that all wheel nuts
are properly tightened. See
Wheel Nut
Torque in the Index.
