Federal law requires tire manufacturers to place standardized information on the sidewall of
all tires. This information identi¿ es and describes the fundamental characteristics of the tire
and also provides a tire identi¿ cation number for safety standard certi¿ cation and in case of
a recall.

P
Indicates a tire that may be installed on cars, SUVs, minivans and light trucks as designated
by the Tire and Rim Association (T&RA).
N O T E
If your tire size does not begin with a letter this may mean it is designated by either ETRTO
(European Tire and Rim Technical Organization) or JATMA (Japan Tire Manufacturing
Association).

215
“215” is the nominal width of the tire in millimeters. This three-digit number gives the
width in millimeters of the tire from sidewall edge to sidewall edge. In general, the larger
the number, the wider the tire.
6 5
“65” is the aspect ratio. This two-digit number indicates the tire's ratio of height to width.

Tire Information (U.S.A.)
M S or M/S: Mud and Snow
AT: All Terrain.
AS: All Season. The “M
S” or “M/S” indicates that the tire has some functional use in mud
and snow.
U.S. DOT Tire Identi¿ cation Number (TIN)
This begins with the letters “DOT” which indicates the tire meets all federal standards. The
next two numbers or letters are the plant code where it was manufactured, and the last four
numbers represent the week and year the tire was manufactured. For example, the numbers
457 means the 45st week of 1997. After 2000 the numbers go to four digits. For example,
the number 2102 means the 21th week of 2002. The other numbers are marketing codes
used at the manufacturer's discretion. This information is used to contact consumers if a tire
defect requires a recall.
Tire Ply Composition and Materials Used
The number of plies indicates the number of layers of rubber-coated fabric in the tire.
In general, the greater the number of plies, the more weight a tire can support. Tire
manufacturers also must indicate the tire materials, which include steel, nylon, polyester,
and other.
Maximum Load Rating
This number indicates the maximum load in kilograms and pounds that can be carried by the
tire.
Maximum Permissible InÀ ation Pressure
This number is the greatest amount of air pressure that should ever be put in the tire under
normal driving conditions.
Tread Wear, Traction and Temperature Grades
Tread wear: The tread wear grade is a comparative rating based on the wear rate of the tire
when tested under controlled conditions on a speci¿ ed government test course. For example,
a tire graded 150 would wear one and one-half (1 1/2) times as well on the government
course as a tire graded 100.
Traction: The traction grades, from highest to lowest are AA, A, B, and C. The grades
represent the tire's ability to stop on wet pavement as measured under controlled conditions
on speci¿ ed government test surfaces of asphalt and concrete. A tire marked C may have
poor traction performance.
Temperature: The temperature grades are A (the highest), B and C, representing the
tire's resistance to the generation of heat and its ability to dissipate heat when tested under
controlled conditions on a speci¿ ed indoor laboratory test wheel.
Snow Tires
In some heavy snow areas, local governments may require true snow tires, those with very
deeply cut tread. These tires should only be used in pairs or placed on all four wheels. Make
sure you purchase snow tires that are the same size and construction type as the other tires
on your vehicle.

Tire Information (U.S.A.)
Location of the Tire Label (Placard)
You will ¿ nd the tire label containing tire inÀ ation pressure by tire size and other important
information on the driver's side B-pillar or on the edge of the driver's door frame.

SAMPLE


Recommended Tire InÀ ation Pressure
On the tire label you will ¿ nd the recommended tire inÀ ation pressure in both kPa and
psi for the tires installed as original equipment on the vehicle. It is very important that the
inÀ ation pressure of the tires on your vehicle is maintained at the recommended pressure.
You should check the tire pressure regularly to insure that the proper inÀ ation pressure is
maintained.
Refer to Tires on page 9-8 .
N O T E
Tire pressures listed on the vehicle placard or tire information label indicate the
recommended cold tire inÀ ation pressure, measured when the tires are cold, after the vehicle
has been parked for at least 3 hours. As you drive, the temperature in the tire warms up,
increasing the tire pressure.

Glossary of Terms
Tire Placard: A label indicating the OE tire sizes, recommended inÀ ation pressure, and the
maximum weight the vehicle can carry.
Tire Identi¿ cation Number (TIN): A number on the sidewall of each tire providing
information about the tire brand and manufacturing plant, tire size, and date of manufacture.
InÀ ation Pressure: A measure of the amount of air in a tire.
kPa: Kilopascal, the metric unit for air pressure.
psi: Pounds per square inch, the English unit for air pressure.
B-pillar: The structural member at the side of the vehicle behind the front door.
Original Equipment (OE): Describes components originally equipped on the vehicle.
Vehicle Load Limit: The maximum value of the combination weight of occupants and
cargo.
Bead Area of the Tire: Area of the tire next to the rim.
Sidewall Area of the Tire: Area between the bead area and the tread.
Tread Area of the Tire: Area on the perimeter of the tire that contacts the road when it's
mounted on the vehicle.

Seating capacity means the total allowable number of vehicle occupants. Seating capacity
is described on the tire label.

Production options weight is the combination weight of installed regular production
options weighing over 2.3 kilograms in excess of the standard items which they replace,
and not previously considered in the curb weight or accessory weight, including heavy duty
brakes, ride levelers, roof rack, heavy duty battery, and special trim.

Rim is the metal support (wheel) for a tire or a tire and tube assembly upon which the tire

Vehicle Loading
WARNING
Do not tow a trailer with this vehicle:
Towing a trailer with this vehicle is dangerous because it has not been designed to tow a
trailer and doing so will aff ect the drive system which could result in vehicle damage.

This section will guide you in the proper loading of your vehicle, to keep your loaded
vehicle weight within its design rating capability. Properly loading your vehicle will provide
maximum return of vehicle design performance. Before loading your vehicle, familiarize
yourself with the following terms for determining your vehicle's weight ratings, from the
vehicle's Safety Certi¿ cation Label and Tire and Load Information Label:
WARNING
Overloaded Vehicle:
Overloading a vehicle is dangerous. The results of overloading can have serious
consequences in terms of passenger safety. Too much weight on a vehicle's suspension
system can cause spring or shock absorber failure, brake failure, handling or steering
problems, irregular tire wear, tire failure or other damage.
Overloading makes a vehicle harder to drive and control. It also increases the distance
required for stopping. In cases of serious overloading, brakes can fail completely,
particularly on steep grades. The load a tire will carry safely is a combination of the size of
the tire, its load range, and corresponding infl ation pressure.
Never overload the vehicle and always observe the vehicle's weight ratings from the
vehicle's Safety Certifi cation and Tire and Load Information labels.
