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 Buick.

Inflation - Tire Pressure
The Tire-Loading Information label which is located on
the rear edge
of the drivers 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.
245

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).
I
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 Inspection 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.
r-
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.

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
whicrall 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.
Warning: The temperature grade for this tire is
established for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
I
excessive loading, either separately or in combination, !
can cause heat buildup and possible tire failure.
Those grade
b 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.

Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle in good working condition, but also helps the
environment. All recommended maintenance procedures
are important. Improper vehicle maintenance or the
removal of important components can significantly
affect the quality of the air
we breathe. Improper fluid
levels or even the wrong tire inflation can increase the
level of emissions from your vehicle.
To help protect .
our environment, and to help keep your vehicle in good
condition, please maintain your vehicle properly.
How This Part is Organized
The remainder of this part is divided into five sections:
“Section A: Scheduled Maintenance Services” shows
what
to have done and how often. Some of these
services can be complex,
so unless you are technically
qualified and have the necessary equipment, you should
let your dealer’s service department or another qualified
service center
do these jobs.
A CAUTION:
Performing maintenance work on a vehicle can
be dangerous.
In trying to do some jobs, you
can be seriously injured.
Do your own
maintenance work only if you have the required
know-how and the proper tools and equipment
for the job.
If you have any doubt, have a
qualified technician do the work.
