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 de ne 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
Speci cation):Original equipment tires designed to
GM’s speci c tire performance criteria have a TPC
speci cation code molded onto the sidewall. GM’s TPC
speci cations 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 Identi cation Number (TIN):The letters and
numbers following DOT (Department of Transportation)
code is the Tire Identi cation 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 5-68.

(F) Tire Size:A combination of letters and numbers
de ne a tire’s width, height, aspect ratio, construction
type and service description. The letter T as the
rst character in the tire size means the tire is for
temporary use only.
(G) TPC Spec (Tire Performance Criteria
Speci cation):Original equipment tires designed to
GM’s speci c tire performance criteria have a TPC
speci cation code molded onto the sidewall. GM’s TPC
speci cations meet or exceed all federal safety
guidelines. Compact Spare Tire Example
5-58

Aspect Ratio:The relationship of a tire’s height to
its width.
Belt:A rubber coated layer of cords that is located
between the plies and the tread. Cords may be made
from steel or other reinforcing materials.
Bead:The tire bead contains steel wires wrapped by
steel cords that hold the tire onto the rim.
Bias Ply Tire:A pneumatic tire in which the plies are
laid at alternate angles less than 90 degrees to the
centerline of the tread.
Cold In ation Pressure:The amount of air pressure in
a tire, measured in pounds per square inch (psi) or
kilopascals (kPa) before a tire has built up heat
from driving. SeeIn ation - Tire Pressure on page 5-62.
Curb Weight:This means the weight of a motor
vehicle with standard and optional equipment including
the maximum capacity of fuel, oil and coolant, but
without passengers and cargo.
DOT Markings:A code molded into the sidewall of a
tire signifying that the tire is in compliance with the U.S.
Department of Transportation (DOT) motor vehicle
safety standards. The DOT code includes the Tire
Identi cation Number (TIN), an alphanumeric designator
which can also identify the tire manufacturer, production
plant, brand and date of production.GVWR:Gross Vehicle Weight Rating, seeLoading
Your Vehicle on page 4-29.
GAWR FRT:Gross Axle Weight Rating for the front
axle, seeLoading Your Vehicle on page 4-29.
GAWR RR:Gross Axle Weight Rating for the rear axle,
seeLoading Your Vehicle on page 4-29.
Intended Outboard Sidewall:The side of an
asymmetrical tire, that must always face outward when
mounted on a vehicle.
Kilopascal (kPa):The metric unit for air pressure.
Light Truck (LT-Metric) Tire:A tire used on light duty
trucks and some multipurpose passenger vehicles.
Load Index:An assigned number ranging from 1 to 279
that corresponds to the load carrying capacity of a tire.
Maximum In ation Pressure:The maximum air
pressure to which a cold tire may be in ated. The
maximum air pressure is molded onto the sidewall.
Maximum Load Rating:The load rating for a tire at the
maximum permissible in ation pressure for that tire.
Maximum Loaded Vehicle Weight:The sum of curb
weight; accessory weight; vehicle capacity weight;
and production options weight.

Courtesy Transportation
To enhance your ownership experience, we and our
participating dealers are proud to offer Courtesy
Transportation, a customer support program for
new vehicles.
The Courtesy Transportation program is offered to
customers in conjunction with the Bumper-to-Bumper
coverage provided by the New Vehicle Limited Warranty.
Several transportation options are available when
warranty repairs are required. This will reduce your
inconvenience during warranty repairs.
Scheduling Service Appointments
When your vehicle requires warranty service, you should
contact your dealer and request an appointment. By
scheduling a service appointment and advising
your service consultant of your transportation needs,
your dealer can help minimize your inconvenience.
If your vehicle cannot be scheduled into the service
department immediately, keep driving it until it can be
scheduled for service, unless, of course, the problem is
safety-related. If it is, please call your dealership, let
them know this, and ask for instructions.
If the dealer requests that you simply drop the vehicle off
for service, you are urged to do so as early in the work
day as possible to allow for the same day repair.

Transportation Options
Warranty service can generally be completed while you
wait. However, if you are unable to wait, GM helps
to minimize your inconvenience by providing several
transportation options. Depending on the circumstances,
your dealer can offer you one of the following:
Shuttle Service
Participating dealers can provide you with shuttle
service to get you to your destination with minimal
interruption of your daily schedule. This includes
one-way or round trip shuttle service to a destination
up to 10 miles (16 km) from the dealership.
Public Transportation or Fuel
Reimbursement
If your vehicle requires overnight warranty repairs,
reimbursement of public transportation expenses may
be available, for up to a maximum of ve days. In
addition, should you arrange transportation through a
friend or relative, reimbursement for reasonable
fuel expenses may be available, up to a ve-day
maximum. Claim amounts should re ect actual costs
and be supported by original receipts.
Courtesy Rental Vehicle
Your dealer may arrange to provide you with a courtesy
rental vehicle or reimburse you for a rental vehicle
that you obtain if your vehicle is kept for a warranty
repair. Reimbursement will be limited to a maximum
amount per day and must be supported by receipts. This
requires that you sign and complete a rental agreement
and meet state, local and rental vehicle provider
requirements. Requirements vary and may include
minimum age requirements, insurance coverage, credit
card, etc. You are responsible for fuel usage charges
and may also be responsible for taxes, levies,
usage fees, excessive mileage or rental usage beyond
the completion of the repair.
Generally it is not possible to provide a like-vehicle as a
courtesy rental.
Additional Program Information
Courtesy Transportation is available during the
Bumper-to-Bumper warranty coverage period, but it is
not part of the New Vehicle Limited Warranty. A
separate booklet entitledWarranty and Owner
Assistance Informationfurnished with each new vehicle
provides detailed warranty coverage information.
