2009 GMC SIERRA 1500 tire size

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 near the tire
size. If the tires have an all-season tread design, the TPC
spec number will be followed by a MS, for mud and snow.
SeeTire Sidewall Labeling on page 5-68for additional
information.
GM recommends replacing tires in sets of four (or six
if your vehicle has dual rear wheels). This is because
uniform tread depth on all tires will help keep your vehicle
performing most like it did when the tires were new.
Replacing less than a full set of tires can affect the
braking and handling performance of your vehicle.
SeeTire Inspection and Rotation on page 5-84for
information on proper tire rotation.
{CAUTION:
Mixing tires could cause you to lose control
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

CAUTION: (Continued)
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 your
vehicle’s wheels.
{CAUTION:
If you use bias-ply tires on the 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
the 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
could 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 5-79.
Your vehicle’s original equipment tires are listed on
the Tire and Loading Information label. SeeLoading the
Vehicle on page 4-34, for more information about the
Tire and Loading Information label and its location on
your vehicle.
Different Size Tires and Wheels
If you add wheels or tires that are a different size than
your original equipment wheels and tires, this could affect
the way your vehicle performs, including its braking, ride
and handling characteristics, stability, and resistance
to rollover. Additionally, if your vehicle has electronicsystems such as anti-lock brakes, rollover airbags,
traction control, and electronic stability control, the
performance of these systems can be affected.
{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 5-86andAccessories
and Modifications on page 5-4for additional information.

Tire Chains
{CAUTION:
If your vehicle has dual wheels or P265/65R18,
P275/55R20 or LT265/70R17 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.
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.
CAUTION: (Continued)
CAUTION: (Continued)
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 does not have dual
wheels and has a tire size other than P265/65R18,
P275/55R20 or LT265/70R17, 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.

Spare Tire
Your 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 5-76andLoading the Vehicle on page 4-34for
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 5-100andStoring
a Flat or Spare Tire and Tools on page 5-110.
Notice:If the vehicle has four-wheel drive and the
different size spare tire is installed on the vehicle,
do not drive in four-wheel drive until you can
have your at tire repaired and/or replaced.
You could damage the vehicle, and the repair
costs would not be covered by your warranty.
Never use four-wheel drive when the different
size spare tire is installed on the vehicle.Your vehicle may have a different size spare tire
than the road tires 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 four-wheel
drive and the different size spare tire is installed, keep the
vehicle in two-wheel drive.
After installing the spare tire on your vehicle, you should
stop as soon as possible and make sure the spare tire
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, the spare tire will be
available in case you need it again.
Do not mix tires and wheels of different sizes, because
they will not t. Keep your spare tire and its wheel
together. 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.
