Use this rotation pattern if the
vehicle has different size tires
on the front and rear.
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 Pressure0309andVehicle
Load Limits0226.
Reset the Tire Pressure Monitor
System. SeeTire Pressure
Monitor Operation0312.
Check that all wheel nuts are
properly tightened. See“Wheel
Nut Torque”underCapacities
and Specifications0362.
{Warning
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, a cloth or a paper
towel can be used; however, use
ascraperorwirebrushlaterto
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. Do not get
grease on the flat wheel
mounting surface or on the
wheel nuts or bolts.
When It Is Time for New
Tires
Factors such as maintenance,temperatures, driving speeds,vehicle loading, and road conditionsaffect the wear rate of the tires.
Treadwear indicators are one way totell when it is time for new tires.Treadwear indicators appear whenthe tires have only 1.6 mm (1/16 in)or less of tread remaining. SeeTireInspection0315andTire Rotation0315.

on proper tire rotation. However,
if it is necessary to replace only
one axle set of worn tires, place
the new tires on the rear axle.
Winter tires with the same speed
rating as the original equipment
tires may not be available for H,
V, W, a n d Z R s p e e d r a t e d t i r e s .
Never exceed the winter tire's
maximum speed capability when
using winter tires with a lower
speed rating.
{Warning
Tires could explode during
improper service. Attempting
to mount or dismount a tire
could cause injury or death.
Only your dealer or authorized
tire service center should
mount or dismount the tires.
{Warning
Mixing tires of different sizes
(other than those originally
installed on the vehicle), brands,
or types may cause loss of
control of the vehicle, resulting in
acrashorothervehicledamage.
Use the correct size, brand, and
type of tire on all four wheels.
{Warning
Using bias-ply tires on the
vehicle may cause the wheel
rim flanges to develop cracks
after many miles of driving.
Atireand/orwheelcouldfail
suddenly and cause a crash.
Use only radial-ply tires with
the wheels on the vehicle.
If the vehicle tires must be
replaced with a tire that does not
have a TPC Spec number, make
sure they are the same size,
load range, speed rating, and
construction (radial) as the
original tires.
Vehicles that have a tire
pressure monitoring system
could give an inaccurate
low-pressure warning if non-TPC
Spec rated tires are installed.
SeeTire Pressure Monitor
Operation0312.
The Tire and Loading
Information label indicates the
original equipment tires on the
vehicle. SeeVehicle Load Limits
0226.
Different Size Tires and
Wheels
If wheels or tires are installed thatare a different size than the originalequipment wheels and tires, vehicleperformance, including its braking,ride and handling characteristics,stability, and resistance to rollovermay be affected. If the vehicle haselectronic systems such as antilockbrakes, rollover airbags, traction

control, electronic stability control,or All-Wheel Drive, the performanceof these systems can also beaffected.
{Warning
If different sized wheels are used,
there may not be an acceptable
level of performance and safety if
tires not recommended for those
wheels are selected. This
increases the chance of a crash
and serious injury. Only use GM
specific wheel and tire systems
developed for the vehicle, and
have them properly installed by a
GM certified technician.
SeeBuying New Tires0317andAccessories and Modifications0272.
Uniform Tire Quality
Grading
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 tires,
compact 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.
Quality grades can be found
where applicable on the tire
sidewall between tread shoulder
and maximum section width. For
example:
Treadwear 200 Traction AATemperature A
All Passenger Car Tires Must
Conform to Federal Safety
Requirements In Addition To
These Grades.
Treadwear
The treadwear grade is a
comparative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test
course. For example, a tire
graded 150 would wear one and
one-half (1Ω) 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 significantly from the

Chevrolet SS Sedan Owner Manual (GMNA-Localizing-U.S.-10122752) -2017 - crc - 8/31/16
320 Vehicle Care
norm due to variations in driving
habits, service practices and
differences in road
characteristics and climate.
Traction
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
specified 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.
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

performance which all
passenger car tires must meet

Standard No. 109. Grades B and
Arepresenthigherlevelsof
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 alignedand balanced at the factory toprovide the longest tire life and bestoverall performance. Adjustments towheel alignment and tire balancingare not necessary on a regularbasis. Consider an alignment checkif there is unusual tire wear or thevehicle is significantly pulling to oneside or the other. Some slight pull tothe left or right, depending on thecrown of the road and/or other roadsurface variations such as troughsor ruts, is normal. If the vehicle isvibrating when driving on a smoothroad, the tires and wheels may needto be rebalanced. See your dealerfor proper diagnosis.
Wheel Replacement
Replace any wheel that is bent,cracked, or badly rusted orcorroded. If wheel nuts keep comingloose, the wheel, wheel bolts, andwheel nuts should be replaced.If the wheel leaks air, replace it.

Chevrolet SS Sedan Owner Manual (GMNA-Localizing-U.S.-10122752) -2017 - crc - 8/31/16
Vehicle Care 321
Some aluminum wheels can berepaired. See your dealer if any ofthese conditions exist.
Yo u r d e a l e r w i l l k n o w t h e k i n d o fwheel that is needed.
Each new wheel should have thesame load-carrying capacity,diameter, width, offset, and bemounted the same way as the one itreplaces.
Replace wheels, wheel bolts, wheelnuts, or Tire Pressure MonitorSystem (TPMS) sensors with newGM original equipment parts.
{Warning
Using the wrong replacement
wheels, wheel bolts, or wheel
nuts can be dangerous. It could
affect the braking and handling of
the vehicle. Tires can lose air,
and cause loss of control, causing
acrash.Alwaysusethecorrect
wheel, wheel bolts, and wheel
nuts for replacement.
Caution
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.
Used Replacement Wheels
{Warning
Replacing a wheel with a used
one is dangerous. How it has
been used or how far it has been
driven may be unknown. It could
fail suddenly and cause a crash.
When replacing wheels, use a
new GM original equipment
wheel.
Tire Chains
{Warning
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 loss of
control and a crash. Use another
type of traction device only if its
manufacturer recommends it for
the vehicle's tire size combination
and road conditions. Follow that
manufacturer's instructions. To
avoid vehicle damage, drive
slowly and readjust or remove the
traction device if it contacts the
vehicle. Do not spin the wheels.
If traction devices are used, install
them on the rear tires.

322 Vehicle Care
If a Tire Goes Flat
It is unusual for a tire to blow outwhile driving, especially if the tiresare maintained properly. SeeTires0303.Ifairgoesoutofatire,itismuch more likely to leak out slowly.But if there is ever a blowout, hereare a few tips about what to expectand what to do:
If a front tire fails, the flat tirecreates a drag that pulls the vehicletoward that side. Take your foot offthe accelerator pedal and grip thesteering wheel firmly. Steer tomaintain lane position, and thengently brake to a stop, well off theroad, if possible.
Arearblowout,particularlyonacurve, acts much like a skid andmay require the same correction asused in a skid. Stop pressing theaccelerator pedal and steer tostraighten the vehicle. It may bevery bumpy and noisy. Gently braketo a stop, well off the road,if possible.
{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
Lifting a vehicle and getting under
it to do maintenance or repairs is
dangerous without the
appropriate safety equipment and
training. If a jack is provided with
the vehicle, it is designed only for
changing a flat tire. If it is used for
anything else, you or others could

be badly injured or killed if the
vehicle slips off the jack. If a jack
is provided with the vehicle, only
use it for changing a flat tire.
If a tire goes flat, avoid further tireand wheel damage by driving slowlyto a level place, well off the road,if possible. Turn on the hazardwarning flashers. SeeHazardWarning Flashers0127.
{Warning
Changing a tire can be
dangerous. The vehicle can slip
off the jack and roll over or fall
causing injury or death. Find a
level place to change the tire. To
help prevent the vehicle from
moving:
