Wheels and Tires
Tires
Your new vehicle comes with
high-quality tires made by a
leading tire manufacturer. If you
ever have questions about your
tire warranty and where to
obtain service, see your vehicle
Warranty booklet for details. For
additional information refer to
the tire manufacturer.
{WARNING
.Poorly maintained and
improperly used tires are
dangerous.
.Overloading your tires can
cause overheating as a result
of too much flexing. You
could have a blowout and a
serious accident. SeeVehicle
Load Limits on page 9‑11.
(Continued)
WARNING (Continued)
.Under inflated tires pose the
same danger as overloaded
tires. The resulting crash
could cause serious injury.
Check all tires frequently to
maintain the recommended
pressure. Tire pressure
should be checked when your
tires are cold.
.Over inflated tires are more
likely to be cut, punctured,
or broken by a sudden
impact—such as when you
hit a pothole. Keep tires at
the recommended pressure.
.Worn or old tires can cause a
crash. If your tread is badly
worn, replace them.
.Replace any tires that have
been damaged by impacts
with potholes, curbs, etc.
(Continued)
WARNING (Continued)
.Improperly repaired tires can
cause a crash. Only your
dealer or an authorized tire
service center should repair,
replace, dismount, and mount
the tires.
.Do not spin the tires in
excess of 55 km/h (35 mph)
on slippery surfaces such as
snow, mud, ice, etc.
Excessive spinning may
cause the tires to explode.
See Tire Pressure for High-Speed
Operation
on page 10‑75for inflation
pressure adjustment for high-speed
driving.

Winter Tires
If you expect to drive on snow or ice
covered roads often, you may want
to get winter tires for your vehicle.
All season tires provide good overall
performance on most surfaces but
they may not offer the traction you
would like or the same level of
performance as winter tires on snow
or ice covered roads.
Winter tires, in general, are
designed for increased traction on
snow and ice covered roads. With
winter tires, there may be decreased
dry road traction, increased road
noise, and shorter tread life. After
switching to winter tires, be alert for
changes in vehicle handling and
braking.
See your dealer for details
regarding winter tire availability and
proper tire selection. Also, see
Buying New Tires on page 10‑83.If you choose to use winter tires:.Use tires of the same brand and
tread type on all four wheel
positions.
.Use only radial ply tires of the
same size, load range, and
speed rating as the original
equipment 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 winter tires with a lower
speed rating, never exceed the tire's
maximum speed capability.
Low-Profile Tires
If your vehicle has P235/50R18,
245/45ZR19, P245/45R19, 255/
40ZR19 or 285/35ZR19 size
tires, they are classified as
low‐profile tires. These tires are
designed for very responsive
driving on wet or dry pavement.
You may also notice more road noise with low‐profile
performance tires and that they
tend to wear faster.
Notice:If the vehicle has
low‐profile tires, they are more
susceptible to damage from
road hazards or curb impact
than standard profile tires.
Tire and/or wheel assembly
damage can occur when
coming into contact with road
hazards like, potholes,
or sharp edged objects,
or when sliding into a curb.
The vehicle warranty does not
cover this type of damage.
Keep tires set to the correct
inflation pressure and, when
possible avoid contact with
curbs, potholes, and other
road hazards.

(E) Tire Inflation:The
temporary use tire or compact
spare tire should be inflated to
420 kPa (60 psi). For more
information on tire pressure and
inflation see Tire Pressure
on
page 10‑74
.
(F) Tire Size
:A combination of
letters and numbers define a
tire's width, height, aspect ratio,
construction type, and service
description. The letter T as the
first character in the tire size
means the tire is for temporary
use only.
(G) TPC Spec (Tire
Performance Criteria
Specification)
:Original
equipment tires designed to
GM's specific tire performance
criteria have a TPC specification
code molded onto the sidewall.
GM's TPC specifications meet or
exceed all federal safety
guidelines.
Tire Designations
Tire Size
The following illustration shows
an example of a typical
passenger vehicle tire size.
(A) Passenger (P‐Metric) Tire:
The United States version of a
metric tire sizing system. The
letter P as the first character in
the tire size means a passenger
vehicle tire engineered to
standards set by the U.S. Tire
and Rim Association.
(B) Tire Width
:The three‐digit
number indicates the tire section
width in millimeters from
sidewall to sidewall. (C) Aspect Ratio
:A two‐digit
number that indicates the tire
height‐to‐width measurements.
For example, if the tire size
aspect ratio is 60, as shown in
item C of the illustration, it would
mean that the tire's sidewall is
60 percent as high as it is wide.
(D) Construction Code
:A
letter code is used to indicate
the type of ply construction in
the tire. The letter R means
radial ply construction; the
letter D means diagonal or bias
ply construction; and the letter B
means belted‐bias ply
construction.
(E) Rim Diameter
:Diameter of
the wheel in inches.

10-76 Vehicle Care
For this example, you would set the
inflation pressure for high‐speed
driving at 44 psi (300 kPa).
Tire Pressure Monitor
System
The Tire Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tire pressure
levels. The TPMS sensors monitor
the air pressure in your tires and
transmit tire pressure readings to a
receiver located in the vehicle.
Each tire, including the spare
(if provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
tire inflation pressure label, you
should determine the proper tire
inflation pressure for those tires.)As an added safety feature, your
vehicle has been equipped with a
tire pressure monitoring system
(TPMS) that illuminates a low tire
pressure telltale when one or more
of your tires is significantly
under‐inflated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them
to the proper pressure. Driving on a
significantly under‐inflated tire
causes the tire to overheat and can
lead to tire failure. Under‐inflation
also reduces fuel efficiency and tire
tread life, and may affect the
vehicle's handling and stopping
ability.
Please note that the TPMS is
not a substitute for proper tire
maintenance, and it is the driver's
responsibility to maintain correct tire
pressure, even if under‐inflation has
not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.Your vehicle has also been
equipped with a TPMS malfunction
indicator to indicate when the
system is not operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start‐ups as
long as the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire
pressure as intended. TPMS
malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.

Black plate (77,1)Cadillac CTS/CTS-V Owner Manual - 2011
Vehicle Care 10-77
Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or
alternate tires and wheels allow the
TPMS to continue to function
properly.
SeeTire Pressure Monitor
Operation
on page 10‑77for
additional information.

Tire Pressure Monitor
Operation
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS is designed to warn the
driver when a low tire pressure
condition exists. TPMS sensors are
mounted onto each tire and wheel
assembly, excluding the spare tire
and wheel assembly, if the vehicle
has one. The TPMS sensors
monitor the air pressure in the
vehicle's tires and transmits the tire
pressure readings to a receiver
located in the vehicle.
When a low tire pressure condition
is detected, the TPMS illuminates
the low tire pressure warning light
located on the instrument panel
cluster. If the warning light comes on, stop as soon as possible and
inflate the tires to the recommended
pressure shown on the tire loading
information label. See
Vehicle Load
Limits on page 9‑11.
Using the Driver Information Center
(DIC), the driver can also check tire
pressure levels using the DIC. For
additional information and details
about the DIC operation and
displays see Driver Information
Center (DIC)
on page 5‑27and
Tire Messageson page 5‑43.
A DIC warning message to check
the pressure in a specific tire is also
shown on the DIC display screen.
The low tire pressure warning light
and the DIC warning message come
at each ignition cycle until the tires
are inflated to the correct inflation
pressure.

Black plate (79,1)Cadillac CTS/CTS-V Owner Manual - 2011
Vehicle Care 10-79
.The TPMS sensor matching
process was not done or not
completed successfully after
rotating the vehicle's tires. The
DIC message should go off after
successfully completing the
sensor matching process. See
“TPMS Sensor Matching
Process”later in this section.
.One or more TPMS sensors are
missing or damaged. The DIC
message and the TPMS
malfunction light should go off
when the TPMS sensors are
installed and the sensor
matching process is performed
successfully. See your dealer for
service.
.Replacement tires or wheels do
not match your vehicle's original
equipment tires or wheels. Tires
and wheels other than those
recommended for your vehicle
could prevent the TPMS from
functioning properly. See Buying
New Tires on page 10‑83.
.Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning it
cannot detect or signal a low tire
condition. See your dealer for
service if the TPMS malfunction
light and DIC message comes on
and stays on.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. Any time you
replace one or more of the TPMS
sensors or rotate your vehicle's
tires, the identification codes need
to be matched to the new tire/wheel
position. The sensors are matched
to the tire/wheel positions in the
following order: driver side front tire,
passenger side front tire, passenger
side rear tire, and driver side rear
tire using a TPMS diagnostic tool.
See your dealer for service. The TPMS sensors can also be
matched to each tire/wheel position
by increasing or decreasing the
tire's air pressure. If increasing the
tire's air pressure, do not exceed
the maximum inflation pressure
indicated on the tire's sidewall. To
decrease the tire's air-pressure use
the pointed end of the valve cap, a
pencil-style air pressure gauge,
or a key.
You have two minutes to match the
first tire/wheel position, and
five minutes overall, to match all
four tire/wheel positions. If it takes
longer than two minutes, to match
the first tire and wheel, or more than
five minutes to match all four tire
and wheel positions, the matching
process stops and you need to
start over.
The TPMS matching process is
outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON/
RUN with the engine off.

Tire Rotation
Tire rotation is not
recommended if the vehicle has
P235/50R18, 245/45ZR19 or
255/40R19 size tires on the front
wheels and P265/45R18, 275/
40ZR19 or 285/35R19 size tires
on the rear wheels.
Different tire sizes should not be
rotated front to rear. Each tire
and wheel should only be used
in its original front or rear
position.
Tire rotation is recommended if
the vehicle has the same size
tires on all four wheel positions.
These tires should be rotated
every 12 000 km (7,500 miles).
SeeScheduled Maintenance
on
page 11‑3
. The purpose of a regular tire
rotation is to achieve a uniform
wear for all tires on the vehicle.
This will ensure that the vehicle
continues to perform most like it
did when the tires were new.
Any time you notice unusual
wear, rotate the tires as soon as
possible and check wheel
alignment. Also check for
damaged tires or wheels.
SeeWhen It Is Time for New
Tires
on page 10‑82and
Wheel
Replacement
on page 10‑88.
Use the rotation pattern shown
here when rotating tires of the
same size installed on all four
wheel positions.
The compact spare tire, if the
vehicle has one, is not included
in the tire rotation.
