2006 CADILLAC DTS PROFESSIONAL tire type

Professional Vehicle
The proper ination of the tires on your professional
vehicle depends on the type of tires on it.
If your vehicle has P235/60R17 size tires, the cold
ination pressure is 41 psi (284 kPa).
If your vehicle has LT235/60R17E size tires, the cold
ination pressure depends on the vehicle mass and
should be determined by the vehicle coach-builder.
A tire and loading information label provided by the
nal stage manufacturer should be attached to the
B-pillar on the driver’s side of the vehicle. If the nal
stage manufacturer’s label is not present, the
coach-builder should be consulted. Do not use the
tire pressures indicated on the General Motors label.
These tire pressures are for the incomplete vehicle
and are not the correct tire pressures for the
completed professional vehicle.
Operation at ination pressures below this
recommendation may cause your tires to become
overloaded.
Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) is designed
to monitor the amount of pressure in your vehicle’s
tires using radio and sensor technology. A TPMS
sensor, mounted onto the vehicle’s full-size tire and
wheel assembly, transmits tire pressure readings to a
receiver located in the vehicle. The compact spare
tire and wheel does not have a TPMS sensor.
Tire pressure status and tire pressure warnings are
shown on the Driver Information Center (DIC) display.
For additional information and details about the DIC
operation and displays seeDIC Controls and Displays
on page 3-72andDIC Warnings and Messages on
page 3-76.
If a low tire pressure condition is detected, the TPMS
will display the CHECK TIRE PRESSURE warning
message on the DIC and, at the same time, illuminate
the low tire pressure warning symbol, on the instrument
panel cluster.
You may notice, during cooler weather conditions, that
the low tire pressure warning symbol and the CHECK
TIRE PRESSURE message will display when the vehicle
is rst started and then turn off as you start to drive
the vehicle. This could be an early indicator that the tire
pressures are getting low and need to be checked
and inated to the proper pressure.

Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your 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 5-64andWheel Replacement
on page 5-69for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The rst rotation
is the most important. SeeScheduled Maintenance
on page 6-4.
If your vehicle has a compact spare tire, it should not be
included in the tire rotation process. Use the four-tire
rotation pattern shown.A ve-tire rotation pattern may be used for your
professional vehicle, if it has a full-size spare tire and
wheel assembly that matches the original equipment
tires and wheels in size, type and brand. The correct
ve-tire rotation pattern is shown.
After the tires have been rotated, adjust the front and
rear ination pressures as shown on the Tire and
Loading Information label. SeeLoading Your Vehicle on
page 4-31.
Vehicles that have the Tire Pressure Monitor System
(TPMS) will need to have the sensors reset after a tire
rotation is performed. SeeTire Pressure Monitor
System on page 5-59. Four-Tire Rotation Pattern

Buying New Tires
GM has developed and matched specic tires for your
vehicle. The original equipment tires installed on
your vehicle, when it was new, were designed to meet
General Motors Tire Performance Criteria Specication
(TPC spec) system rating. If you need replacement
tires, GM strongly recommends that you get tires with
the same TPC Spec rating. This way, your vehicle
will continue to have tires that are designed to give the
same performance and vehicle safety, during normal
use, as the original tires.
GM’s exclusive TPC Spec system considers over a
dozen critical specications that impact the overall
performance of your vehicle, including brake system
performance, ride and handling, traction control, and tire
pressure monitoring performance. GM’s TPC Spec
number is molded onto the tire’s sidewall by the
tire manufacturer. If the tires have an all-season tread
design, the TPC spec number will be followed by an MS
for mud and snow. SeeTire Sidewall Labeling on
page 5-50for additional information.{CAUTION:
Mixing tires could cause you to lose control of
your vehicle while driving. If you mix tires of
different sizes, brands, or types (radial and
bias-belted tires), the vehicle may not handle
properly, and you could have a crash. Using
tires of different sizes, brands, or types may
also cause damage to your vehicle. Be sure to
use the correct size, brand, and type of tires
on all wheels.
Your vehicle may have a compact spare tire
and wheel assembly. If the vehicle has a
compact spare tire and wheel, they have the
same overall diameter as your vehicle’s
full-size tires and wheels. Because they were
designed and developed for use on your
vehicle, it is all right to drive your vehicle with
the compact spare installed properly. Compact
spare tires are designed for temporary use
only. SeeSpare Tire on page 5-82.
5-65

{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 5-59.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). See
Loading Your Vehicle on page 4-31.
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.
5-66

{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 5-65andAccessories
and Modications on page 5-3for 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.
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.
5-67

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.
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, readjust or remove the
device if it is contacting your vehicle, and do
not spin your vehicle’s wheels. If you do nd
traction devices that will t, install them on the
front tires.
5-70

After installing the spare tire on your vehicle, you should
stop as soon as possible and make sure the spare is
correctly inated. Have the damaged or at road tire
repaired or replaced as soon as you can and installed
back onto your vehicle. This way, a spare tire will be
available in case you need it again.
Your vehicle may have a different size spare tire
than the road tire originally installed on your vehicle.
This spare tire was developed for use on your vehicle,
so it is all right to drive on it.
If your vehicle has a spare tire that does not match your
vehicle’s original road tires and wheels in size and
type, do not include the spare in the tire rotation.
Appearance Care
Cleaning the Inside of Your Vehicle
Your vehicle’s interior will continue to look its best if
it is cleaned often. Although not always visible, dust and
dirt can accumulate on your upholstery. Dirt can
damage carpet, fabric, leather, and plastic surfaces.
Regular vacuuming is recommended to remove particles
from your upholstery. It is important to keep your
upholstery from becoming and remaining heavily soiled.
Soils should be removed as quickly as possible. Your
vehicle’s interior may experience extremes of heat
that could cause stains to set rapidly.Lighter colored interiors may require more frequent
cleaning. Use care because newspapers and garments
that transfer color to your home furnishings may also
transfer color to your vehicle’s interior.
When cleaning your vehicle’s interior, only use cleaners
specically designed for the surfaces being cleaned.
Permanent damage may result from using cleaners on
surfaces for which they were not intended. Use glass
cleaner only on glass. Remove any accidental over-spray
from other surfaces immediately. To prevent over-spray,
apply cleaner directly to the cleaning cloth.
Notice:If you use abrasive cleaners when cleaning
glass surfaces on your vehicle, you could scratch
the glass and/or cause damage to the integrated
radio antenna and the rear window defogger. When
cleaning the glass on your vehicle, use only a
soft cloth and glass cleaner.
Many cleaners contain solvents that may become
concentrated in your vehicle’s breathing space. Before
using cleaners, read and adhere to all safety
instructions on the label. While cleaning your vehicle’s
interior, maintain adequate ventilation by opening
your vehicle’s doors and windows.
Dust may be removed from small buttons and knobs
using a small brush with soft bristles.
Your GM dealer has a product for cleaning your
vehicle’s glass. Should it become necessary, you can
also obtain a product from your GM dealer to remove
odors from your vehicle’s upholstery.
