minimum speed of 20 km/h
(12 mph). A dash (-) or pressure
value will display in the DIC.
See Driver Information Center
(DIC) (Base Level)0136 or
Driver Information Center
(DIC) (Uplevel) 0139. A warning
message displays in the DIC if
a problem occurs during the
relearn process.
Tire Inspection
We recommend that the
tires, including the spare
tire, if the vehicle has one,
be inspected for signs of
wear or damage at least
once a month.
Replace the tire if:
.The indicators at three or
more places around the
tire can be seen.
.There is 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.
Tire Rotation
Tires should be rotated
according to the interval
specified in the
Maintenance Schedule. See
Maintenance Schedule
0 471.
Tires are rotated to
achieve a uniform wear for
all tires. The first rotation is
the most important.
Anytime unusual wear is
noticed, rotate the tires as
soon as possible, check for proper tire inflation
pressure, and check for
damaged tires or wheels.
If the unusual wear
continues after the
rotation, check the wheel
alignment. See When It Is
Time for New Tires
0437
and
Wheel Replacement 0441.
Use this rotation pattern if
the vehicle has different
size tires on the front
and rear.

436 Vehicle Care
Different tire sizes should
not be rotated front
to rear.
Use this rotation pattern
when rotating tires of the
same size installed on all
four wheel positions.
Adjust the front and rear
tires to the recommended
inflation pressure on the
Tire and Loading
Information label after the
tires have been rotated.See Tire Pressure
0427
and
Vehicle Load Limits 0261.
Reset the Tire Pressure
Monitor System. See Tire
Pressure Monitor
Operation 0431.
Check that all wheel nuts
are properly tightened. See
“Wheel Nut Torque” under
Capacities and
Specifications 0482.
{Warning
Rust or dirt on a wheel,
or on the parts to which it
is fastened, can cause
wheel nuts to become
loose over time. The
wheel could come off and
cause a crash. When
changing a wheel, remove
any rust or dirt from
places where the wheel
attaches to the vehicle. In
(Continued)
Warning (Continued)
an emergency, a cloth or
paper towel can be used;
however, use a scraper
or wire brush later to
remove all rust or dirt.
Lightly coat the center of
the wheel hub with wheel
bearing grease after a
wheel change or tire
rotation to prevent
corrosion or rust build-up.
{Warning
Do not apply grease to
the wheel mounting
surface, wheel conical
seats, or the wheel nuts
or bolts. Grease applied
to these areas could
cause a wheel to become
loose or come off,
resulting in a crash.

Vehicle Care 437
When It Is Time for
New Tires
Factors, such as maintenance,
temperatures, driving speeds,
vehicle loading, and road
conditions affect the wear
rate of the tires.
Treadwear indicators are one
way to tell when it is time for
new tires. Treadwear
indicators appear when the
tires have only 1.6 mm (1/16 in)
or less of tread remaining. See
Tire Inspection0435 and
Tire Rotation 0435. The rubber in tires ages over
time. This also applies to the
spare tire, if the vehicle has
one, even if it is never used.
Multiple factors including
temperatures, loading
conditions, and inflation
pressure maintenance affect
how fast aging takes place.
GM recommends that tires,
including the spare if
equipped, be replaced after six
years, regardless of tread
wear. To identify the age of a
tire, use the tire manufacture
date, which is the last four
digits of the DOT Tire
Identification Number (TIN)
molded into one side of the
tire sidewall. The last four
digits of the TIN indicate the
tire manufactured date. The
first two digits represent the
week and the last two digits,
the year. For example, the
third week of the year 2020
would have a 4-digit DOT date
of 0320. Week 01 is the first
full week (Sunday through
Saturday) of each year.
Vehicle Storage
Tires age when stored
normally mounted on a parked
vehicle. Park a vehicle that will
be stored for at least a month
in a cool, dry, clean area away
from direct sunlight to slow
aging. This area should be free
of grease, gasoline, or other
substances that can
deteriorate rubber.
Parking for an extended
period can cause flat spots on
the tires that may result in
vibrations while driving. When
storing a vehicle for at least a
month, remove the tires or
raise the vehicle to reduce the
weight from the tires.
Buying New Tires
GM has developed and
matched specific tires for
the vehicle. The original
equipment tires installed
were designed to meet
General Motors Tire
Performance Criteria

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-16500419) -

Vehicle Care 441
this tire is based on
straight-ahead braking
traction tests, and does not
include acceleration,
cornering, hydroplaning,
or peak traction
characteristics.
Temperature
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
specified 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 whichall passenger car tires must
meet under the Federal
Motor 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 inflated and
not overloaded. Excessive
speed, underinflation,
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 were
aligned and balanced at the
factory to provide the longest
tire life and best overall
performance. Adjustments to
wheel alignment and tire balancing are not necessary
on a regular basis. Consider an
alignment check if there is
unusual tire wear or the
vehicle is significantly pulling
to one side or the other. Some
slight pull to the left or right,
depending on the crown of the
road and/or other road
surface variations such as
troughs or ruts, is normal.
If the vehicle is vibrating when
driving on a smooth road, the
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.
Some aluminum wheels can be
repaired. See your dealer if
any of these conditions exist.
Your dealer will know the kind
of wheel that is needed.

Warning (Continued)
If traction devices are used,
install them on the tires of
the drive axle only.
If a Tire Goes Flat
It is unusual for a tire to blow
out while driving, especially if
the tires are maintained
properly. If air goes out of a
tire, it is much more likely to
leak out slowly. See Tires
0418 for additional
information. But if there ever
is a blowout, here are a few
tips about what to expect and
what to do:
If a front tire fails, the flat tire
creates a drag that pulls the
vehicle toward that side. Take
your foot off the accelerator
pedal and grip the steering
wheel firmly. Steer to maintain
lane position, and then gently
brake to a stop, well off the
road, if possible. A rear blowout, particularly on
a curve, acts much like a skid
and may require the same
correction as used in a skid.
Stop pressing the accelerator
pedal and steer to straighten
the vehicle. It may be very
bumpy and noisy. Gently brake
to a stop, well off the road,
if possible.
The vehicle has no spare tire,
no tire changing equipment,
and no place to store a tire.
If the vehicle has run-flat tires,
there is no need to stop on
the side of the road to change
a flat tire. See Run-Flat Tires
0
420.
If the vehicle has self-sealing
tires, see Self-Sealing Tires
0 420. Tread punctures
typically will not cause tires to
lose air. However, if the vehicle
does get a flat tire, there is no
spare tire, tire changing
equipment, or place to store a
tire. Contact Roadside
Assistance for help.
{Warning
Driving on a flat tire will
cause permanent damage to
the tire. Re-inflating a tire
after it has been driven on
while severely underinflated
or flat may cause a blowout
and a serious crash. Never
attempt to re-inflate a tire
that has been driven on
while severely underinflated
or flat. Have your dealer or
an authorized tire service
center repair or replace the
flat tire as soon as possible.
{Warning
Special tools and
procedures are required to
service a run-flat tire.
If these special tools and
procedures are not used,
injury or vehicle damage may
occur. Always be sure the
proper tools and

procedures, as described in
the service manual,
are used.
If a tire goes flat, avoid further
tire and wheel damage by
driving slowly to a level place,
well off the road, if possible.
Turn on the hazard warning
flashers. See Hazard Warning
Flashers 0156.
This vehicle may come with a
tire sealant and compressor
kit. To use the tire sealant and
compressor kit, see Tire
Sealant and Compressor Kit
0 444.
Tire Sealant and
Compressor Kit
{Warning
Idling a vehicle in an
enclosed area with poor
ventilation is dangerous.
Engine exhaust may enter
(Continued)
Warning (Continued)
the vehicle. Engine exhaust
contains carbon monoxide
(CO) which cannot be seen
or smelled. It can cause
unconsciousness and even
death. Never run the engine
in an enclosed area that has
no fresh air ventilation. For
more information, see
Engine Exhaust0276.
{Warning
Overinflating a tire could
cause the tire to rupture
and you or others could be
injured. Be sure to read and
follow the tire sealant and
compressor kit instructions
and inflate the tire to its
recommended pressure. Do
not exceed the
recommended pressure.
{Warning
Storing the tire sealant and
compressor kit or other
equipment in the passenger
compartment of the vehicle
could cause injury. In a
sudden stop or collision,
loose equipment could strike
someone. Store the tire
sealant and compressor kit
in its original location.
If this vehicle has a tire sealant
and compressor kit, there may
not be a spare tire or tire
changing equipment, and on
some vehicles there may not
be a place to store a tire.
The tire sealant and
compressor can be used to
temporarily seal punctures up
to 6 mm (0.25 in) in the tread
area of the tire. It can also be
used to inflate an
underinflated tire.

Vehicle Care 445
If the vehicle is equipped with
tires containing acoustic foam,
tire sealant performance may
be decreased in cold climates.
If the tire has been separated
from the wheel, has damaged
sidewalls, or has a large
puncture, the tire is too
severely damaged for the tire
sealant and compressor kit to
be effective. See Roadside
Assistance Program0489.
Read and follow all of the tire
sealant and compressor kit
instructions.
The kit includes:1. Sealant Canister Inlet Valve
2. Sealant/Air Hose
3. Base of Sealant Canister

Tire Sealant
Read and follow the safe
handling instructions on the
label adhered to the tire
sealant canister (4).
Check the tire sealant
expiration date on the tire
sealant canister. The tire
sealant canister (4) should be
replaced before its expiration
date. Replacement tire sealant
canisters are available at your
local dealer.
There is only enough sealant
to seal one tire. After usage,
the tire sealant canister must
be replaced.
Using the Tire Sealant and
Compressor Kit to
Temporarily Seal and
Inflate a Punctured Tire
When using the tire sealant
and compressor kit during cold
temperatures, warm the kit in
a heated environment for
five minutes. This will help to
inflate the tire faster.
