Customer Information and Reporting Safety Defects
■ 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 when tested under controlled condi-
tions on a specified 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 specified
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 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 UNDER-INFLATION/OVERLOADING/
DAMAGE-FOLLOW OWNER’S MANUAL AND PLACARD IN
VEHICLE-FREQUENTLY CHECK INFLATION PRESSURE AND
INSPECT FOR DAMAGE.
