Inflation-Tire Pressure
The CertificatiodTire label which is 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 a
mile. 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 flexin1
Too much heat
Tire overloadine
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
I
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 kPa).
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.

Treadwear
The treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded
150 would
wear one and a half
(1%) times as well
on the government course as a tire
graded
100. The relative performance of
tires depends upon the actual conditions
of their use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices and differences in road
characteristics and climate.
Traction-A, B, C
The traction grades, from highest to
lowest are:
A, B, and C. They represent
the tire’s ability to stop on wet pavement
as measured under controlled conditions
on specified government test surfaces of
asphalt and concrete.
A tire marked C
may have poor traction performance.
Warning: The traction grade assigned
to this tire
is based on braking (straight-
ahead) traction tests and does not
include cornering (turning) traction.
Temperature-A, B, C
The temperature grades are A (the
highest),
B, and C, representing the
tire’s resistance to the generation of heat
and its ability to dissipate heat when
tested under controlled conditions
on a
specified indoor laboratory test wheel.
Sustained high temperature can cause
the material
of the tire to degenerate and
reduce tire life, and excessive
temperature can lead to sudden tire
failure. The grade
C corresponds to a
level
of performance which all
passenger car tires must meet under the
Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent
higher levels
of performance on the
laboratory test wheel than the minimum
required by law.

Temperature-A, B, C (CONT)
Warning: The temperature grade for
this tire is established for a tire that is
properly inflated and not overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in
combination, can cause heat buildup
and possible tire failure.
Those grades are molded on the
sidewalls of passenger car tires.
While the tires available as standard or
optional equipment on General Motors
vehicles may vary with respect to these
grades, all such tires meet General
Motors performance standards and have
been approved for use on General Motors vehicles.
All passenger type
(P Metric) tires must conform to Federal
safety requirements in addition to these
grades.
Wheel Alignment and
Tire Balance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to have
your wheels aligned again. However,
if
you notice unusual tire wear or your
vehicle pulling one way or the other, the
alignment may need to be reset. If you
notice your vehicle vibrating when
driving on a smooth road, your wheels
may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked
or badly rusted. If wheel nuts keep
coming loose, the wheel, wheel bolts,
and wheel nuts should be replaced. If
the wheel leaks air out, replace it
(except some aluminum wheels, which
can sometimes be repaired). See your
Oldsmobile dealer
if any of these
conditions exist.
Your dealer will know the kind of wheel
you need.
Each new wheel should have the same
load carrying capacity, diameter, width,
offset, and be mounted the same way as
the one it replaces.
If you need
to replace any of your
wheels, wheel bolts, or wheel nuts,
replace them only with
new GM
original equipment parts.
This way, you
will be sure you have the right wheel,
wheel bolts, and wheel nuts for your Oldsmobile model.

Customer Satisfaction Procedure
Your satisfaction and goodwill are
important to your dealer and
Oldsmobile. Normally, any problems
with the sales transaction or the
operation
of your vehicle will be
resolved
by your dealer's Sales or
Service Departments. Sometimes,
however, despite the best intentions
of
all concerned, misunderstandings can
occur.
If your concern has not been
resolved

following
steps should be taken:
STEP ONE: Discuss your problem with
a member

Complaints can often be quickly
resolved at that level.

already been reviewed with the Sales, Service or
Parts Manager, contact the
owner
of the dealership or the General
Manager.
STEP TWO: If after contacting a
member of Dealership Management,
it
appears your problem cannot be
resolved
by the dealership without
further help, contact the Oldsmobile
