{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.
If you must replace your vehicle’s tires with those
that do not have a TPC Spec number, make
sure they are the same size, load range, speed
rating, and construction type (radial and
bias-belted tires) as your vehicle’s original tires.Vehicles that have a tire pressure monitoring
system may give an inaccurate low-pressure
warning if non-TPC Spec rated tires are installed
on your vehicle. Non-TPC Spec rated tires
may give a low-pressure warning that is higher or
lower than the proper warning level you would
get with TPC Spec rated tires. SeeTire Pressure
Monitor System on page 405.
Your vehicle’s original equipment tires are listed
on the Tire and Loading Information Label.
This label is attached to the vehicle’s center pillar
(B-pillar). SeeLoading Your Vehicle on page 321,
for more information about the Tire and Loading
Information Label and its location on your vehicle.

Different Size Tires and Wheels
If you add wheels or tires that are a different size
than your original equipment wheels and tires,
this may affect the way your vehicle performs,
including its braking, ride and handling
characteristics, stability, and resistance to rollover.
Additionally, if your vehicle has electronic
systems such as, anti-lock brakes, traction control,
and electronic stability control, the performance
of these systems can be affected.
{CAUTION:
If you add different sized wheels, your
vehicle may not provide an acceptable
level of performance and safety if tires not
recommended for those wheels are
selected. You may increase the chance
that you will crash and suffer serious
injury. Only use GM specic wheel and
tire systems developed for your vehicle,
and have them properly installed by a GM
certied technician.SeeBuying New Tires on page 411and
Accessories and Modications on page 332for
additional information.
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 (NHTSA), 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 (UTQG)
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.
414

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 or tire chain clearance
to the body and chassis.
SeeChanging a Flat Tire (CTS Only) on page 424
for more information.
Used Replacement Wheels
{CAUTION:
Putting a used wheel on your vehicle is
dangerous. You cannot know how it has
been used or how far it has been driven.
It could fail suddenly and cause a crash.
If you have to replace a wheel, use a new
GM original equipment wheel.
417

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.
Lifting Your Vehicle (CTS-V)
{CAUTION:
Lifting a vehicle can cause an injury.
The vehicle can slip off the jack and roll
over you or other people. You and they
could be badly injured. Find a level place
to lift your vehicle. To help prevent the
vehicle from moving:
1. Place the shift lever in REVERSE (R)
and rmly apply the parking brake.
2. Turn off the engine.
To be even more certain the vehicle will
not move, you can put blocks in front of
and behind the wheels. Also seeParking
Your Vehicle (Manual Transmission) on
page 132andParking Brake on page 128
for additional information.
418

Lifting From the Rear
The rear lifting points can be accessed from either
side of your vehicle, in front of the rear tires.1. Locate the rear lifting points using the
diagram shown above and corresponding
triangular-shaped hoisting notches located in
the plastic molding. The rear lifting location
is about 7 inches (17.8 cm) from the
front edge of the rear wheel well.
2. Be sure to place a block or pad between the
jack and the vehicle.
3. Lift the vehicle with the jack, making sure the
jack is centered on the rear lifting point.
SeeDoing Your Own Service Work on page 333
for additional information.

If a Tire Goes Flat
It is unusual for a tire to “blowout” while you are
driving, especially if you maintain your tires
properly. SeeTires on page 392. If air goes out of a
tire, it is much more likely to leak out slowly. But if
you should ever have a “blowout”, 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 blowout, particularly on a curve, acts much
like a skid and may require the same correction
you’d use in a skid. In any rear blowout, 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.If a tire goes at, and your vehicle has a spare
tire, seeChanging a Flat Tire (CTS Only) on
page 424. This information shows you how to use
your vehicle’s tire changing equipment and
how to change a at tire safely.
{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous
without the appropriate safety equipment
and training. The jack provided with your
vehicle is designed only for changing a
at tire. If it is used for anything else, you
or others could be badly injured or killed
if the vehicle slips off the jack. Use the
jack provided with your vehicle only for
changing a at tire.
422

Run-Flat Tires (CTS-V)
If your vehicle has run-at tires, there is no spare
tire and no tire changing equipment. Run-at
tires can operate effectively with no air pressure
for a limited distance and speed. Your vehicle also
has a Tire Pressure Monitor (TPM) which will
alert you if there is a loss of tire pressure in any of
the tires. These tires perform so well without
any air pressure that a Tire Pressure Monitor
(TPM) is used to alert you when there is a low tire
condition.
{CAUTION:
When the low tire warning light is
displayed on the instrument panel cluster,
your vehicle’s handling capabilities will
be reduced during severe maneuvers.
If you drive too fast, you could lose control
of your vehicle. You or others could be
injured. Do not drive over 55 mph (90 km/h)
CAUTION: (Continued)
CAUTION: (Continued)
when the low tire warning light is
displayed. Drive cautiously and check
your tire pressures as soon as you can.
SeeRun-Flat Tires (CTS-V) on page 400and
Tire Pressure Monitor System on page 405,
for additional information.
{CAUTION:
Special tools and procedures are required
to service a run-at tire. If these special
tools and procedures are not used you or
others could be injured and your vehicle
could be damaged. Always be sure the
proper tools and procedures, as described
in the service manual, are used.
To order a service manual seeService
Publications Ordering Information on page 501.
