socket. The new bulb
must be aligned properly, then
push
it in the socket. Reinstall the socket, taillight,
and rear

Two labels on your vehicle show how much weight it
may properly carry. The Tire-Loading Information label
found on the deck lid, tells you the proper size, speed
rating and recommended inflation pressures for the tires
on your vehicle. It also gives you important information
about the number of people that can be in your vehicle

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 Buick. If your
spare tire
is a different brand than your road tires, you

Inflation - Tire Pressure
The Tire-Loading Information label which is on the deck 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:
0 Too much flexing
Too much heat
Tire overloading
Bad wear
0 Bad handling
Bad fuel economy.
If your tires have too much air (overinflation),
you can get:
Unusual wear
0 Bad handling
0 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 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.

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.
FRONT
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.

When It’s Time for New Tires
One way to tell when it’s
time for new tires
is to
check the treadwear
indicators, which will
appear when your tires
have
only 2/32 inch
(1.6 mm) or less of tread
remaining.
You need a new tire
if
0 You can see the indicators at three or more places
around the tire.
0 You can see cord or fabric showing through the tire’s
rubber.
0 The tread or sidewall is cracked, cut or snagged deep
enough to show cord or fabric.
The tire has a bump, bulge or split.
The tire has a puncture, cut, or other damage that
can’t be repaired well because of the size or location
of the damage.
Buying New Tires
To find out what kind and size of tires you need, look at
the Tire-Loading Information label.
The tires installed on your vehicle
when it was new had
a Tire Performance Criteria Specification (TPC Spec)
number on each tire’s sidewall. When you get new tires,
get ones
with that same TPC Spec number. That way,
your vehicle
will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction, ride and other things during normal service on
your vehicle. If your tires have an all-season tread
design, the TPC number will be followed by a
“MS”
(for mud and snow).
If you ever replace your tires with those not having a
TPC Spec number, make sure they are the same size,
load range, speed rating and construction type (bias,
bias-belted or radial) as your original tires.

Uniform Tire Quality Grading
The following infortnation relates to the system
developed by the United States National Highway
Traffic Safety Administration which grades tires by
tfeadwear, traction and temperature performance. (This
applies only to vehicles sold in the United States.)
Treadwear
The treadwear grade is a comparative rating based on
the wear rate
of the tire when tested under controlled
conditiolis on a specified government test course. For
example, a tire graded
150 would wear one and a half
(1 1/2) 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, ffom 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.

ProCarManuals.com

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.
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.
These 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.
