1997 GMC JIMMY tires

Mixing tires could cause you to lose control while
driving.
If you mix tires of different sizes or types
(radial and bias-belted tires), the vehicle may not
handle properly, and you could have
a crash.
Using tires
of different sizes may also cause
damage to
your vehicle. Be sure to use the same
size and type tires
on all wheels.
It’s all right to drive with your compact spare
(if you have one). It was developed for
use on
your vehicle.
Uniform Tire Quality Grading
The following information relates to the system
developed
by the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear. traction and temperature performance. (This
applies only to vehicles
sold in the United States.) The
grades are molded on the sidewalls of most passenger
car tires. The Uniform Tire Quality Grading system does not
apply to deep tread, winter-type snow tires,
space-saver or temporary use spare tires, tires with
nominal
rim diameters of 10 to 12 inches (25 to 30 cm),
or to some limited-production tires.
While the tires available on General Motors passenger
cars and light trucks may vary
with respect to these
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
c Urades, they rnust also conform to Federal safety
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
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 clilnate.

Traction -- A, B, C
The tmction 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 perf’ormance.
Wxning: The traction grade assigned
to this tire is based
on braking (straight ahead) traction tests and does not
include cornering (tuning) traction.
Temperature -- A, B, C
The temperature grades are A (,the highest), B, and C.
representing the tire‘s resistance to the gencration of
heat and its ability to dissipate heat when tested undcr
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.
Warnin?: Thc ten~perat~u-e pxde for this tire is

overloaded. Excessive speed. underinflation, or
excessive loading. either separatcly or in combination.

Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
care1’uIly at the factory to give you the longest tire life
and best overdl performance.
lee1 Replacement
~epl~e ;my wheel that is bent. cracked, or badly rusted
01- corrocled. If wheel n~~ts keep coming loose. the wheel,
wheel bolts and wheel nuts should be 1-eplacec1.
If the
wheel leaks air, replace it (except some aluminum
wheels. which cm sometimes be repaired). See your
GM dcalcr if any of’ these conditions exist.
6-46

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 to have the
right wheel. wheel bolts
and wheel nuts for your vehicle.
I
A CAUTION: r)
Using the wrong replacement wheels, wheel bolts
or wheel nuts on your vehicle can be dangerous.
It could affect the braking and handling of your
vehicle, make your tires lose
air and make you
lose control. You could have a collision in which
you or others could be injured.
Alwrays use the
correct wheel, wheel
bolts and wheel nuts
for replacement.
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 or tire
chain clearance
to the body and chassis.

Used Replacement Wheels
'
A CAUTION:
Putting a used wheel on your vehicle is
dangerous. You can't know how it's been used or
how
far it's been driven. It could fail suddenly
and cause an accident.
If you have to replace a
wheel, use
a new GkI original equipment wheel.

Tire Chains
NOTICE:
If your vehicle has P235/75R15, P235/70K15 or
31xlOSOR15LT/C size tires, 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.
NOTICE: (Continued)
NOTICE: (Continued)
If you do hd a traction device that will fit, install
them on the rear tires.
If you have other size tires, use tire chains only
where legal and only when you must. Use only
SAE Class “S” type chains that are the proper
size for your tires. Install them on the drive axle
tires (,four-wheel-drive vehicles can use chains on both axles) and tighten them as tightly
as possible
with the ends securely fastened. Drive slowly and
follow the chain manufacturer’s instructions.
If
you can hear the chains contacting your vehicle,
stop and retighten them.
If the contact continues,
slow down until it stops. Driving
too fast or
spinning the wheels with
chains on will damage
your vehicle.

Exterior painted surfaces are subject to aging, weather
and chemical fdlout that can take their
toll over a period
of years. You can help to keep the paint finish looking
new by keeping your vehicle garaged or covered
whenever possible.
Protecting Exterior Bright Metal Parts
Bright metal parts should be cleaned regularly to keep
their luster. Washing
with water is all that is usually
needed. However. you may use chrome polish on
chrome or stainless steel trim.
if necessary.
Use special care
with aluminum trim. To avoid
damaging protective
trim, never use auto or chrome
polish, steam or caustic
soap to clean aluminum. A
coating of wax, rubbed to high polish, is recommended
for
all bright metal parts.
Cleaning Aluminum Wheels
(If Equipped)
Keep your wheels clean wing a soft clean cloth with
mild
soap and water. Rinse with cle.an water. After
rinsing thoroughly,
dry with a soft clean towel. A wax
may then be applied. The surface
of these wheels
is similar to the painted
surface of your vehicle. Don't use strong soaps.
chemicals, abrasive polishes, abrasive cleaners or
abrasive cleaning brushes on then1 because you could
damage the surface.
Don't take your vehicle through an automatic car wash
that has silicon carbide tire cleaning brushes. These
brushes can
also damage the surface of these wheels.
Cleaning Tires
To clean YOLK tires, use a stiff brush with a tire cleaner.
NOTICE:
When applying a tire dressing always take care to
wipe off any overspray or splash from all painted
surfaces
on the body or wheels of the vehicle.
Petroleum-based products may damage the paint finish.
Sheet Metal Damage
If your vehicle is damaged and requires sheet metal
repair
or replacement, make sure the body repair shop
applies anti-corrosion material to the parts repaired or
replaced
to restore corrosion protection.
