1998 OLDSMOBILE BRAVADA flat tire

Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to I3 000 km). Any time you notice unusual
wear, rotate your tires as
soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See “When
It’s Time for New Tires” and
“Wheel Replacement” later
in this section for
more information.
The purpose of regular rotation is to achieve more
lrniform wear for all tires on the vehicle. The first
rotation is the most important. See ”Scheduled
Maintenance Services”
in the Index for scheduled
rotation intervals. When rotating your
tires, always use the correct rotation
pattern shown here.
If your vehicle has a compact spare tire, don’t include it
in your tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown
on the
CertificatiodTire label. Make certain that all wheel nuts
are properly tightened. See “Wheel
Nut Torque’‘ in
the Index.
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after a time. The wheel could come off and cause
an accident. When you change
a wheel, remove
any rust or dirt from places where the wheel
attaches to the vehicle. In an emergency, you can
use a cloth or a paper towel
to do this; but be
sure to use a scraper or wire brush later, if you
need to, to get all the rust or dirt off. (See
“Changing a Flat Tire” in the Index.)

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 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, from highest to lowest, are
A, B, and C, and 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.
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.

NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper
height, vehicle ground clearance and tire
clearance to the body and chassis.
See “Changing a Flat Tire” in the Index for
more information.
Used Replacement Wheels
/1 MI CP ““‘3N:
Putting a used wheel on your vehicle is
dangerous. You can’t know how it’s been used or
hotv
far it’s been driven. It could fail suddenly
and cause an accident.
If you have to replace a
wheel, use a new GM original equipment wheel.
Tire Chains
NOTICE:
______
Don’t use tire chains. They can damage your
vehicle because there’s not enough clearance.
Use another type of traction device only if its
manufacturer recommends it for use on your
vehicle and tire size combination and road
conditions. Follow that manufacturer’s
instructions. To help avoid damage to your
vehicle, drive slowly, readjust or remove the
device
if it’s contacting your vehicle, and don’t
spin your wheels.
Appearance Care
Remember, cleaning products can be hazardous. Some
are toxic. Others can burst into flame
if you strike a
match or get them on a hot part of the vehicle. Some are
dangerous if you breathe their fumes in a closed space.
When you use anything from a container to clean your
vehicle, be sure to follow the manufacturer’s warnings
and instructions. And always open your doors or
windows when you’re cleaning the inside.

Your Vehicle and the EnvironmcC
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 can even
affect the quality of the air we breathe. Improper fluid
levels or the wrong tire inflation can increase
the level
of emissions from your vehicle. To help protect our
environment. and to keep your vehicle
in good
condition, please maintain your vehicle properly.
How This Section is Organized
The remainder of this section is divided into five parts:
“Part 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 retailer’s service department or another
qualified service center do these
jobs.

Part B: Owner Checks and Services
Listed below are owner checks and services which
should be performed at the intervals specified to help
ensure the safety, dependability and emission control
performance
of your vehicle.
Be sure any necessary repairs are completed at once.
Whenever any fluids or lubricants are added to your
vehicle, make sure they are the proper ones, as shown
in
Part D.
At Each Fuel Fill
Engine Oil Level Check
Check the engine oil level and add the proper oil if
necessary. See “Engine Oil.’ in the Index for
further details.
Engine Coolant Level Check
Check the engine coolant level and add DEX-COOL@
coolant mixture if necessary. See “Engine Coolant” in
the Index for further details.
Windshield Washer Fluid 1,evel Check
Check the windshield washer fluid level in the
windshield washer tank and add the proper fluid
if
necessary. See “Windshield Washer Fluid’’ in the Index
for further details.
At Least Once a Month
Tire Inflation Check
Make sure tires are inflated to the cosrect pressures. See
”Tires” in the Index for further details.
Cassette Deck Service
Clean cassette deck. Cleaning should be done every
50 hours of tape play. See “Audio Systems” in the
Index for further details.
