Customer Information and Reporting Safety Defects
P215/65R15 95H is an example of a tire size and load index rating.
Here is an explanation of the various components of that tire size and
load index rating. Note that the tire size and load index rating may be
different from the example.
● P
Indicates a tire that may be inst alled on cars, SUVs, minivans and
light trucks as designated by the Tire and Rim Association (T&RA).
If your tire size does not begin with a letter this may mean it is desig-
nated by either ETRTO (European Tire and Rim Technical Organiza-
tion) 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 millimeter s of the tire from sidewall edge
to sidewall edge. In general, the larger the number, the wider the
tire.
● 65
“65” is the aspect ratio. This two-digit number indicates the tire’s
ratio of height to width.
● R
“R” is the tire construc tion symbol. R indicates “Radial ply construc-
tion”.
● 15
“15” is the wheel rim diameter in inches.
● 95
“95” is the Load Index. This two-or three-digit number indicates how
much weight each tire can support.
● H
“H” is the speed rating. The speed rating denotes the maximum
speed for which the use of the tire is rated.

■Maximum Load Rating
This number indicates the maximum load in kilograms and pounds
that can be carried by the tire.
■Maximum Permissible Inflation 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 wh en tested under controlled condi-
tions on a specified government te st 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 specified
government test surfaces of as phalt 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 resist ance to the generation of heat and
its ability to dissipate heat w hen tested under controlled condi-
tions on a specified 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 pur-
chase snow tires that are the same size and construction type as
the other tires on your vehicle.
■SAFETY WARNING
The following safety warning appears on the tire’s sidewall. SERI-
OUS INJURY MAY RESULT FROM: • EXPLOSION OF TIRE/RIM ASSEMBLY DUE TO IMPROPER MOUNTING-MATCH TIRE DIAMETER TO RIM DIAMETER;
NEVER EXCEED 40 psi (275 kPa) TO SEAT BEADS-ONLY
SPECIALLY TRAINED PERSONS SHOULD MOUNT TIRES.
• TIRE FAILURE DUE TO UNDE R-INFLATION/OVERLOADING/
DAMAGE-FOLLOW OWNER’S MANUAL AND PLACARD IN
VEHICLE-FREQUENTLY CHECK INFLATION PRESSURE AND
INSPECT FOR DAMAGE.

T115/70D16 90M is an example of a tire size and load index rating.
Here is an explanation of the various components of that tire size and
load index rating. Note that the tire size and load index rating may be
different from the example.
● T
Indicates a tire that may be inst alled on cars, SUVs, minivans and
light trucks as designated by the Tire and Rim Association (T&RA).
● 11 5
“115” is the nominal width of the ti re in millimeters. This three-digit
number gives the width in millimeter s of the tire from sidewall edge
to sidewall edge. In general, the larger the number, the wider the
tire.
● 70
“70” is the aspect ratio. This two-digit number indicates the tire’s
ratio of height to width.
● D
“D” is the tire construction symbol. D indicates “diagonal ply con-
struction”.
● 16
“16” is the wheel rim diameter in inches.

7-7. Tire Information (U.S.A.)
●Tire Placard: A label indicating the OE tire sizes, recommended
inflation pressure, and the maximu m weight the vehicle can carry.
● Tire Identification 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.
● Inflation 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): De scribes 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 con-
tacts the road when it’s mounted on the vehicle.
● Seating capacity means the total a llowable number of vehicle occu-
pants. Seating capacity is described on the tire label.
● Production options weight is the combination weight of installed
