(D) Tire Identication Number (TIN):The letters
and numbers following DOT (Department of
Transportation) code is the Tire Identication
Number (TIN). The TIN shows the manufacturer
and plant code, tire size, and date the tire
was manufactured. The TIN is molded onto both
sides of the tire, although only one side may have
the date of manufacture.
(E) Tire Ply Material:The type of cord and
number of plies in the sidewall and under the tread.
(F) Uniform Tire Quality Grading (UTQG):Tire
manufacturers are required to grade tires based on
three performance factors: treadwear, traction, and
temperature resistance. For more information see
Uniform Tire Quality Grading on page 419.
(G) Maximum Cold Ination Load Limit:
Maximum load that can be carried and the
maximum pressure needed to support that load.(A) Temporary Use Only:The compact spare
tire or temporary use tire has a tread life of
approximately 3,000 miles (5 000 km) and should
not be driven at speeds over 65 mph (105 km/h).
The compact spare tire is for emergency use when
a regular road tire has lost air and gone at. If
your vehicle has a compact spare tire, see
Compact Spare Tire on page 442andIf a Tire
Goes Flat on page 423.
Compact Spare Tire Example
402

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 471.
When rotating P255/50R20 size tires, always use
the correct rotation pattern shown here.
Do not include the compact spare tire in the tire
rotation.
After the tires have been rotated, adjust the front
and rear ination pressures as shown on the
Tire and Loading Information label.Vehicles that have the Tire Pressure Monitor
System (TPMS) will need to have the TPMS
sensors reset after a tire rotation, seeTire
Pressure Monitor System on page 410.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specications on page 464.
{CAUTION:
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
you change a wheel, remove any rust or
dirt from places where the wheel attaches
to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this;
but be sure to use a scraper or wire brush
later, if needed, to get all the rust or dirt
off. SeeChanging a Flat Tire on page 424.
415

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
(except some aluminum wheels, which can
sometimes be repaired). See your dealer if any of
these conditions exist.
Your dealer will know the kind of wheel you need.
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 on page 424for more
information.
421

Notice:If your vehicle has a tire size other
than P255/50R20 use tire chains only where
legal and only when you must. Use chains that
are the proper size for your tires. Install
them on the tires of the rear axle. Do not use
chains on the tires of the front axle. Tighten
them as tightly as possible with the ends
securely fastened. Drive slowly and follow the
chain manufacturer’s instructions. If you
can hear the chains contacting your vehicle,
stop and retighten them. If the contact
continues, slow down until it stops. Driving
too fast or spinning the wheels with chains on
will damage your vehicle.If a Tire Goes Flat
It is unusual for a tire to blowout while you are
driving, especially if you maintain your vehicle’s
tires properly. 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 would 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.

{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.
If a tire goes at, the next part shows how to use
the jacking equipment to change a at tire safely.
Changing a Flat Tire
If a tire goes at, avoid further tire and wheel
damage by driving slowly to a level place. Turn
on your vehicle’s hazard warning ashers.
SeeHazard Warning Flashers on page 166for
more information.
{CAUTION:
Changing a tire can be dangerous. The
vehicle can slip off the jack and roll over
or fall on you or other people. You and
they could be badly injured or even killed.
Find a level place to change your tire. To
help prevent the vehicle from moving:
1. Set the parking brake rmly.
2. Put the shift lever in PARK (P).
CAUTION: (Continued)
424

5. Tilt the retainer (C) and slip it through the
wheel opening to remove the spare tire
from the cable (B).
6. Turn the wrench clockwise until you feel two
slips or hear two clicks after removing the
spare tire to raise the cable back up.
Do not store a full-size or a at road tire under
the vehicle. SeeStoring a Flat or Spare Tire
and Tools on page 439.To continue changing the at tire, seeRemoving
the Flat Tire and Installing the Spare Tire on
page 429.
If the spare tire will not lower, the secondary latch
may be engaged causing the tire not to lower.
Do the following to check the cable:
1. Check under the
vehicle to see if the
cable is visible. If
it is not visible, see
Secondary Latch
System on
page 436.
428

2. If it is visible, rst try to tighten the cable by
turning the wheel wrench clockwise until you
hear two clicks or feel it skip twice. You
cannot over-tighten the cable.
3. Loosen the cable then by turning the wrench
counterclockwise three or four turns.
4. Tighten the cable all the way and then loosen
it at least two times, if the spare tire has not
lowered.
If the spare tire did lower to the ground,
continue with Step 4 underRemoving the
Spare Tire and Tools on page 426.
If you still cannot lower the spare tire to the
ground, seeSecondary Latch System on
page 436.Removing the Flat Tire and
Installing the Spare Tire
To remove the at tire and install the spare, do
the following:
1. Loosen the wheel nuts, but do not remove
them yet, using the wheel wrench. Turn the
handle about 180 degrees, then ip the handle
back to the starting position. This avoids
taking the wrench off the lug nut for each turn.
429

Secondary Latch System
Your vehicle has an underbody mounted tire hoist
assembly equipped with a secondary latch
system. It is designed to stop the compact spare
tire from suddenly falling off your vehicle if the
cable holding the spare tire is damaged. For the
secondary latch to work, the tire must be
stowed with the valve stem pointing down. See
Storing a Flat or Spare Tire and Tools on page 439
for instructions on storing the spare tire correctly.
{CAUTION:
Before beginning this procedure read all
the instructions. Failure to read and follow
the instructions could damage the hoist
assembly and you and others could get
hurt. Read and follow the instructions
listed next.
{CAUTION:
Someone standing too close during the
procedure could be injured by the jack. If
the spare tire does not slide off the jack
completely, make sure no one is behind
you or on either side of you as you pull
the jack out from the under spare.
436

Storing a Flat or Spare Tire
and Tools
{CAUTION:
Storing a jack, a tire, 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 all these in the
proper place.
Storing the Flat Tire with Third Row
Passengers
1. Put back all tools as they were stored in the
rear storage compartment and put the
compartment cover back on.
2. Use the power third row seat button, near the
liftgate, to tilt the third row seatback forward
slightly.3. Place the at tire in the tire storage bag and
put the tire in an upright position against the
third row seat.
4. Route the tie-down strap through the tire as
shown in the graphic and attach the strap to
the cargo tie-downs in the rear of the vehicle.
5. Tighten the tie-down strap.
