Tire and Loading Information Label
A vehicle specic Tire and Loading Information label
is attached to the vehicle’s center pillar (B-pillar).
With the driver’s door open, you will nd the label
attached below the door lock post (striker). The tire and
loading information label lists the number of occupant
seating positions (A), and the maximum vehicle capacity
weight (B) in kilograms and pounds. The vehicle
capacity weight includes the weight of all occupants,
cargo, and all nonfactory-installed options.The Tire and Loading Information label also lists the
tire size of the original equipment tires (C) and the
recommended cold tire ination pressures (D).
For more information on tires and ination, seeTires on
page 5-47andInation - Tire Pressure on page 5-53.
There is also important loading information on the
Certication/Tire label. It tells you the Gross Vehicle
Weight Rating (GVWR) and the Gross Axle Weight
Rating (GAWR) for the front and rear axles. See
“Certication/Tire Label” later in this section.
Steps for Determining Correct Load Limit
1. Locate the statement “The combined weight of
occupants and cargo should never exceed
XXX kg or XXX lbs” on your vehicle’s placard.
2. Determine the combined weight of the driver and
passengers that will be riding in your vehicle.
3. Subtract the combined weight of the driver and
passengers from XXX kg or XXX lbs. Label Example
4-32

Certication Label
A vehicle specic Certication/Tire label is found on the
rear edge of the driver’s door.
The label shows the size of your original tires and the
ination pressures needed to obtain the gross weight
capacity of your vehicle. This is called the Gross Vehicle
Weight Rating (GVWR). The GVWR includes the
weight of the vehicle, all occupants, fuel, and cargo.The Certication/Tire label also tells you the maximum
weights for the front and rear axles, called the Gross
Axle Weight Rating (GAWR). To nd out the actual loads
on your front and rear axles, you need to go to a
weigh station and weigh your vehicle. Your dealer can
help you with this. Be sure to spread out your load
equally on both sides of the centerline.
Never exceed the GVWR for your vehicle or the GAWR
for either the front or rear axle.
{CAUTION:
Do not load your vehicle any heavier than the
Gross Vehicle Weight Rating (GVWR), or either
the maximum front or rear Gross Axle Weight
Rating (GAWR). If you do, parts on your
vehicle can break, and it can change the way
your vehicle handles. These could cause you
to lose control and crash. Also, overloading
can shorten the life of your vehicle.
Notice:Overloading your vehicle may cause
damage. Repairs would not be covered by your
warranty. Do not overload your vehicle.

If you are using a weight-carrying or a weight-distributing
hitch, the trailer tongue weight (A) should be 10 percent
to 15 percent of the total loaded trailer weight (B).
Do not exceed the maximum allowable tongue weight
for your vehicle.
After you have loaded your trailer, weigh the trailer and
then the tongue, separately, to see if the weights are
proper. If they are not, you may be able to get them right
simply by moving some items around in the trailer.
Total Weight on Your Vehicle’s Tires
Be sure your vehicle’s tires are inated to the upper
limit for cold tires. You will nd these numbers on
the Certication/Tire Label at the rear edge of the
driver’s door, or seeLoading Your Vehicle on page 4-31.
Then be sure you do not go over the GVW limit for
your vehicle, including the weight of the trailer tongue.
Hitches
It is important to have the correct hitch equipment.
Crosswinds, large trucks going by and rough roads
are a few reasons why you will need the right hitch.
Here are some rules to follow:
If you will be pulling a trailer that, when loaded, will
weigh more than 2,000 lbs (900 kg), be sure to use a
properly mounted, weight-carrying hitch and sway
control of the proper size. This equipment is very
important for proper vehicle loading and good
handling when you’re driving.
Will you have to make any holes in the body of your
vehicle when you install a trailer hitch?
If you do, remember to seal the holes when you
remove the hitch. If you do not seal them, deadly
carbon monoxide (CO) from your exhaust can get
into your vehicle. SeeEngine Exhaust on page 2-25.
Dirt and water can, too.

Tire Sidewall Labeling
Useful information about a tire is molded into its
sidewall. The examples below show a typical passenger
vehicle tire and a compact spare tire sidewall.
(A) Tire Size:The tire size is a combination of letters
and numbers used to dene a particular tire’s width,
height, aspect ratio, construction type, and service
description. See the “Tire Size” illustration later in this
section for more detail.(B) TPC Spec (Tire Performance Criteria
Specication):Original equipment tires designed
to GM’s specic tire performance criteria have a
TPC specication code molded onto the sidewall.
GM’s TPC specications meet or exceed all federal
safety guidelines.
(C) DOT (Department of Transportation):The
Department of Transportation (DOT) code indicates that
the tire is in compliance with the U.S. Department of
Transportation Motor Vehicle Safety Standards.
(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 5-58.
(G) Maximum Cold Ination Load Limit:Maximum
load that can be carried and the maximum pressure
needed to support that load. Passenger (P-Metric) Tire Example
5-48

(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, seeCompact Spare Tire on page 5-73
andIf a Tire Goes Flat on page 5-62.
(B) Tire Ply Material:The type of cord and number of
plies in the sidewall and under the tread.(C) Tire Identication Number (TIN):The letters
and numbers following the DOT (Department of
