When It Is Time for New
Tires
Various factors, such as
maintenance, temperatures,
driving speeds, vehicle loading,
and road conditions influence
when you need new tires.
One way to tell when it is time for
new tires is to check the treadwear
indicators, which appear when the
tires have only 1/16 inch (1.6 mm)
or less of tread remaining.The vehicle needs new tires if any
of the following statements are true:•You can see the indicators at
three or more places around
the tire.
•You can see cord or fabric
showing through the tire’s rubber.
•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 cannot be
repaired well because of the size
or location of the damage.
The rubber in tires degrades over
time, even if they are not being used.
This is also true for the spare tire,
if the vehicle has one. Multiple
conditions affect how fast this aging
takes place, including temperatures,
loading conditions, and inflation pressure maintenance. With proper
care and maintenance tires typically
wear out before they degrade due to
age. If you are unsure about the
need to replace the tires as they get
older, consult the tire manufacturer
for more information.
Buying New Tires
GM has developed and matched
specific tires for the vehicle. If you
need replacement tires, GM strongly
recommends that you get tires that
are the same size, brand, load range,
speed rating, and construction type
(radial and bias-belted tires) as the
vehicle’s original tires. This way, the
vehicle will continue to have tires
that are designed to give the same
performance and vehicle safety,
during normal use, as the original
tires. See
Tire Sidewall Labeling on
page 9-44 for additional information.
9-56 Vehicle Care
Wheel Alignment and
Tire Balance
The tires and wheels on the vehicle
were aligned and balanced carefully
at the factory to give the longest tire
life and best overall performance.
Adjustments to wheel alignment and
tire balancing will not be necessary
on a regular basis. However, if there
is unusual tire wear or the vehicle
pulls to one side or the other, the
alignment should be checked. If the
vehicle vibrates when driving on a
smooth road, the tires and wheels
might need to be rebalanced.
See your dealer/retailer for proper
diagnosis.
Wheel Replacement
Replace any wheel that is bent,
cracked or badly rusted or corroded.
If wheel nuts keep coming loose, the
wheel, wheel bolts and wheel nuts
should be replaced. If the wheel
leaks air, replace it (except some
aluminum wheels, which can
sometimes be repaired). See your
dealer/retailer if any of these
conditions exist.
Your dealer/retailer 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 the
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 the vehicle.{CAUTION
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. Always 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.
See If a Tire Goes Flat on page 9-62
for more information.
9-60 Vehicle Care
Wheels and Trim — Aluminum
or Chrome
The vehicle may have either
aluminum or chrome-plated wheels.
Keep the wheels clean using a
soft clean cloth with mild soap
and water. Rinse with clean water.
After rinsing thoroughly, dry with
a soft clean towel. A wax may
then be applied.
Notice:Chrome wheels and
other chrome trim may be
damaged if the vehicle is not
washed after driving on roads
that have been sprayed with
magnesium, calcium or sodium
chloride. These chlorides are
used on roads for conditions
such as ice and dust. Always
wash the vehicle’s chrome with
soap and water after exposure. Notice:
Using strong soaps,
chemicals, abrasive polishes,
cleaners, brushes, or cleaners
that contain acid on aluminum
or chrome-plated wheels,
could damage the surface of the
wheel(s). The repairs would
not be covered by the vehicle
warranty. Use only approved
cleaners on aluminum or
chrome-plated wheels.
The surface of these wheels is
similar to the painted surface of the
vehicle. Do not use strong soaps,
chemicals, abrasive polishes,
abrasive cleaners, cleaners with
acid, or abrasive cleaning brushes
on them because the surface could
be damaged. Do not use chrome
polish on aluminum wheels. Notice:
Using chrome polish on
aluminum wheels could damage
the wheels. The repairs would
not be covered by the vehicle
warranty. Use chrome polish
on chrome wheels only.
Use chrome polish only on
chrome-plated wheels, but avoid
any painted surface of the wheel,
and buff off immediately after
application.
Notice: Driving the vehicle
through an automatic car wash
that has silicone carbide tire
cleaning brushes, could damage
the aluminum or chrome-plated
wheels. The repairs would not be
covered by the vehicle warranty.
Never drive a vehicle that has
aluminum or chrome-plated
wheels through an automatic car
wash that uses silicone carbide
tire cleaning brushes.
9-78 Vehicle Care
Windshield and Wiper Blades
Clean the outside of the windshield
with glass cleaner.
Clean the rubber blades using a
lint free cloth or paper towel soaked
with windshield washer fluid or a mild
detergent. Wash the windshield
thoroughly when cleaning the blades.
Bugs, road grime, sap, and a buildup
of vehicle wash/wax treatments may
cause wiper streaking. Replace the
wiper blades if they are worn or
damaged.
Wipers can be damaged by:
•Extreme dusty conditions
•Sand and salt
•Heat and sun
•Snow and ice, without proper
removal
Tires
Use a stiff brush with tire cleaner to
clean the tires.
Notice:Using petroleum-based
tire dressing products on the
vehicle may damage the paint
nish and/or tires. When applying
a tire dressing, always wipe off
any overspray from all painted
surfaces on the vehicle.
Sheet Metal Damage
If the vehicle is damaged and
requires sheet metal repair or
replacement, make sure the body
repair shop applies anti-corrosion
material to parts repaired or
replaced to restore corrosion
protection.
Original manufacturer replacement
parts will provide the corrosion
protection while maintaining
the vehicle warranty.
Finish Damage
Any stone chips, fractures or deep
scratches in the finish should be
repaired right away. Bare metal will
corrode quickly and may develop into
major repair expense.
Minor chips and scratches can be
repaired with touch-up materials
available from your dealer/retailer.
Larger areas of finish damage can be
corrected in your dealer’s/retailer’s
body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow
removal and dust control can collect
on the underbody. If these are not
removed, corrosion and rust can
develop on the underbody parts such
as fuel lines, frame, floor pan, and
exhaust system even though they
have corrosion protection.
Vehicle Care 9-79
At least every spring, flush these
materials from the underbody
with plain water. Clean any areas
where mud and debris can collect.
Dirt packed in close areas of
the frame should be loosened before
being flushed. Your dealer/retailer
or an underbody car washing
system can do this.
Chemical Paint Spotting
Some weather and atmospheric
conditions can create a chemical
fallout. Airborne pollutants can
fall upon and attack painted surfaces
on the vehicle. This damage can
take two forms: blotchy, ring-shaped
discolorations, and small, irregular
dark spots etched into the paint
surface.
Interior Care
The vehicle’s interior will continue
to look its best if it is cleaned often.
Dust and dirt can accumulate on the
upholstery and cause damage to the
carpet, fabric, leather, and plastic
surfaces. Stains should be removed
quickly as extreme heat could cause
them to set rapidly.
Lighter colored interiors may require
more frequent cleaning. Newspapers
and garments that can transfer color
to home furnishings can also transfer
color to the vehicle’s interior.
Remove dust from small buttons
and knobs with a small brush
with soft bristles.Your dealer/retailer has products
for cleaning the vehicle’s interior.
When cleaning the vehicle’s interior,
only use cleaners specifically
designed for the surfaces that are
being cleaned. Permanent damage
can result from using cleaners on
surfaces for which they were not
intended. Apply the cleaner directly
to the cleaning cloth to prevent
over-spray. Remove any accidental
over-spray from other surfaces
immediately.
Notice:
Using abrasive cleaners
when cleaning glass surfaces on
the vehicle, could scratch the
glass and/or cause damage to
the rear window defogger. When
cleaning the glass on the vehicle,
use only a soft cloth and glass
cleaner.
