2009 HUMMER H3 tires

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/retailer if any of these
conditions exist.
Your dealer/retailer 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, wheel nuts,
or Tire Pressure Monitor System
(TPMS) sensors, replace them only
with new GM original equipment
parts. This way, you will be sure
to have the right wheel, wheel bolts,
wheel nuts, and TPMS sensors
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 5-66for more information.
Used Replacement Wheels
{CAUTION
Putting a used wheel on the
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
If your vehicle has LT285/75R16
or P265/65R18 size tires, do not
use tire chains. They can damage
your vehicle because 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.
(Continued)
CAUTION (Continued)
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
rear tires.Notice:If your vehicle has a
tire size other than LT285/75R16
or P265/65R18 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
creates 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.
If a jack is provided with the
vehicle, it 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. If a jack
is provided with the vehicle, only
use it 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 hazard warning ashers.
SeeHazard Warning Flashers
on page 3-5.
{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
P (Park).

5-66 Service and Appearance Care

To store the jack tool bag and jack:
1. Return the tools to the jack
tool bag.
2. Secure the tool bag to the jack
by securely wrapping the straps
around the jack. Then, slide
the straps through the rings on
the bag and secure.
3. Reinstall the wing nut retainer to
fasten the jack and tool bag
under the rear seat.
Make sure that the wing nut
passes through the tool bag and
the jack before tightening it.
4. Turn the wing nut retainer
clockwise to secure.Spare Tire
The vehicle, when new, had a
fully-inated spare tire. A spare tire
may lose air over time, so check
its ination pressure regularly.
SeeInflation - Tire Pressure on
page 5-51andLoading the Vehicle
on page 4-35for information
regarding proper tire ination and
loading your vehicle. For instruction
on how to remove, install or store
a spare tire, seeRemoving the Flat
Tire and Installing the Spare Tire
on page 5-72andStoring a Flat or
Spare Tire and Tools (H3) on
page 5-78orStoring a Flat or Spare
Tire and Tools (H3T) on page 5-80.
After installing the spare tire on
your vehicle, you should stop
as soon as possible and make sure
the spare is correctly inated.The spare tire does not have a Tire
Pressure Monitor System sensor.
You may get a low pressure warning
light. SeeTire Pressure Monitor
Operation on page 5-54. Have the
damaged or at road tire repaired or
replaced as soon as you can.
Do not mix tires and wheels of
different sizes, because they will not
t. Keep your spare tire and its
wheel together.
5-82 Service and Appearance Care

Tires
To clean the tires, use a stiff brush
with tire cleaner.
Notice:Using petroleum-based
tire dressing products on the
vehicle may damage the paint
nish and/or tires. When applying
a tire dressing, always wipe off
any overspray from all painted
surfaces on the vehicle.
Sheet Metal Damage
If the vehicle is damaged and
requires sheet metal repair or
replacement, make sure the body
repair shop applies anti-corrosion
material to parts repaired or
replaced to restore corrosion
protection.Original manufacturer replacement
parts will provide the corrosion
protection while maintaining
the vehicle warranty.
Finish Damage
Any stone chips, fractures or deep
scratches in the nish should be
repaired right away. Bare metal will
corrode quickly and may develop
into major repair expense.
Minor chips and scratches can be
repaired with touch-up materials
available from your dealer/retailer.
Larger areas of nish damage can be
corrected in your dealer’s/retailer’s
body and paint shop.
Underbody Maintenance
Chemicals used for ice and
snow removal and dust control can
collect on the underbody. If these
are not removed, corrosion and rust
can develop on the underbody
parts such as fuel lines, frame,
oor pan, and exhaust system
even though they have corrosion
protection.
At least every spring, ush these
materials from the underbody
with plain water. Clean any areas
where mud and debris can collect.
Dirt packed in close areas of the
frame should be loosened before
being ushed. Your dealer/retailer or
an underbody car washing system
can do this.
