CHEVROLET SSR 2005 1.G Owners Manual

Buying New Tires
To nd out what kind and size of tires your vehicle
needs, look at the Certication/Tire label or the Tire and
Loading Information label. SeeLoading Your Vehicle
on page 4-29, for examples of these labels and
where they are located on your vehicle.
The tires installed on your vehicle when it was new had
a Tire Performance Criteria Specication (TPC Spec)
number on each tire’s sidewall. When you get new
tires, GM recommends that you get tires with that same
TPC Spec number. That way your vehicle will continue
to have tires that are designed to give proper endurance,
handling, load range, speed rating, traction, ride and
other characteristics during normal service on your
vehicle. If your tires have an all-season tread design,
the TPC number will be followed by an “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.
Winter tires with the same speed rating as your
original equipment tires may not be available for H, V,
W and ZR speed rated tires. If you choose snow
tires with a lower speed rating, never exceed the tire’s
maximum speed capability.{CAUTION:
Mixing tires could cause you to lose control
while driving. If you mix tires of different sizes
(other than those originally installed on your
vehicle) or types (radial and bias-belted tires),
the vehicle may not handle properly, and you
could have a crash. Using tires of different
sizes (other than those originally installed on
your vehicle) may also cause damage to your
vehicle. Be sure to use the correct size and
type tires on all four wheels.
{CAUTION:
If you use bias-ply tires on your vehicle, the
wheel rim anges could develop cracks after
many miles of driving. A tire and/or wheel
could fail suddenly, causing a crash. Use only
radial-ply tires with the wheels on your vehicle.

Uniform Tire Quality Grading
Quality grades can be found where applicable on the
tire sidewall between tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA Temperature A
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
grades, they must also conform to federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specied government test course.
For example, a tire graded 150 would wear one and
a half (1.5) 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 signicantly from the norm
due to variations in driving habits, service practices and
differences in road characteristics and climate.
Traction – AA, A, B, C
The traction grades, from highest to lowest, are AA, A,
B, and C. Those grades represent the tire’s ability
to stop on wet pavement as measured under controlled
conditions on specied 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 straight-ahead braking
traction tests, and does not include acceleration,
cornering, hydroplaning, or peak traction characteristics.
5-62

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 specied 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 inated and not
overloaded. Excessive speed, underination, or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
Wheel Alignment and Tire Balance
The tires and wheels on your vehicle were aligned
and balanced carefully at the factory to give you
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 you notice unusual tire wear or your vehicle pulling to
one side or the other, the alignment may need to be
checked. If you notice your vehicle vibrating when
driving on a smooth road, your tires and wheels may
need to be rebalanced. See your dealer 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 if any of these conditions exist.
Your dealer will know the kind of wheel you need.
5-63

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.
{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 clearance to the
body and chassis.
{CAUTION:
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 a crash. 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.
5-64

{CAUTION:
Never use oil or grease on studs or the threads
of the wheel nuts. If you do, the wheel nuts
might come loose and the wheel could fall off,
causing a crash.
{CAUTION:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to become
loose and even come off. This could lead to a
crash. Be sure to use the correct wheel nuts.
If you have to replace them, be sure to get new
GM original equipment wheel nuts.Notice:Improperly tightened wheel nuts can lead
to brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
torque specication.
Used Replacement Wheels
{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 a crash. If you have to replace a
wheel, use a new GM original equipment wheel.
5-65

Tire Chains
{CAUTION:
Do not use tire chains. There is not enough
clearance. Tire chains used on a vehicle
without the proper amount of clearance can
cause damage to the brakes, suspension or
other vehicle parts. The area damaged by the
tire chains could cause you to lose control of
your vehicle and you or others may be injured
in a crash. 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, re-adjust or remove the
device if it is contacting your vehicle, and do
not spin your wheels. If you do nd traction
devices that will t, install them on the
rear tires.
If a Tire Goes Flat
Your vehicle has no spare tire, no tire changing
equipment and no place to store a tire.
It is unusual for a tire to blow out while you are driving,
especially if you maintain your tires properly. See
Tires on page 5-52. If air goes out of a tire, it’s much
more likely to leak out slowly. But if you should
ever have a blow out here are a few tips about what to
expect and what to do:
If a front tire fails, the at tire will create a drag that
pulls the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel rmly.
Steer to maintain lane position, and then gently brake
to a stop well out of the traffic lane.
A rear blow out, particularly on a curve, acts much
like a skid and may require the same correction
you would use in a skid. In any rear blow out, remove
your foot from the accelerator pedal. Get the vehicle
under control by steering the way you want the vehicle
to go. It may be very bumpy and noisy, but you can
still steer. Gently brake to a stop, well off the road
if possible.
5-66

If a tire goes at, avoid further tire and wheel damage
by driving slowly to a level place and stopping.
Then do this:
1. Turn on the hazard warning ashers.
2. Park your vehicle. If your vehicle has an automatic
transmission, set the parking brake rmly and put
the shift lever in PARK (P). SeeShifting Into
Park (P) (Automatic Transmission) on page 2-24
for additional information. If your vehicle has
a manual transmission, move the shift lever to
REVERSE (R) and set the parking brake rmly.
SeeParking Your Vehicle (Manual Transmission)
on page 2-25for additional information.
3. Turn off the engine.
4. Inspect the at tire.
If the tire has been separated from the wheel or has
damaged sidewalls or large tears that allow rapid
air loss, call a tire repair facility. SeeRoadside
Assistance Program on page 7-6.If the at tire is due to a slow leak caused by a nail
or other similar road hazard, the tire inator kit may be
used to repair the damaged tire temporarily. The kit
uses a liquid tire sealant to seal small punctures in the
tread area of the tire. The at tire is then inated to
at least 26 psi (179 kPa) and driven to evenly distribute
the tire sealant. The tire pressure is checked after
driving for a maximum of 10 minutes to see if the slow
leak has been stopped. If the tire pressure is 19 psi
(131 kPa) or more, inate the tire up to the standard
operating pressure as shown on the tire and loading
information label. This label is attached to the
vehicle’s B-pillar below the driver’s door latch. See
Ination - Tire Pressure on page 5-58.
You should have the damaged tire repaired as soon as
possible. The tire sealant is a temporary repair only.
For more information regarding the tire inator kit
seeTire Inator Kit on page 5-68.
Notice:If the tire pressure has dropped below
19 psi (131 kPa), the vehicle should not be driven.
Damage to the tire may be severe and the sealant
will not be effective. Contact Roadside Assistance,
seeRoadside Assistance Program on page 7-6.

5-68

Tire Sealant
The kit contains a liquid sealant that when injected into
a at tire, may temporarily repair nail holes or cuts
in the tread area of the tire. The tire sealant cannot
repair tire damage caused while driving on a at tire or
a tire that has had a “blow out” or a tire that has
punctures in the sidewall areas. The tire sealant solution
is a one-time use application for one tire only. Check
the tire sealant expiration date; the sealant may not be
as effective beyond the expiration date. The tire
sealant can be peeled off easily after drying.
Using Tire Sealant
To apply the tire sealant, do the following:
1. Turn the valve cap on the tire valve
counterclockwise to remove it.
2. Remove the valve core using the valve core tool
provided in the tire inator kit. An extra valve
core is also provided in the kit.
3. Shake the bottle to make sure the sealant is
well mixed.4. Attach the tire sealant lling hose to the bottle
of tire sealant to pierce the seal on the bottle.
5. Remove the sealing plug from the end of the
lling hose and insert the end of the hose over
the tire valve.
6. Hold the bottle upside down over the tire valve
and squeeze the sealant into the tire until the
bottle is empty.
7. Remove the sealant lling hose from the tire valve
and reinstall the sealing plug.
8. Insert the valve core back into the tire valve.
Turn the valve core tool clockwise to secure
the valve core.
Once the tire sealant is applied, you can use the
compressor to inate the tire. SeeAir Compressor on
page 5-70for instructions.
