REPORTING SAFETY DEFECTS  
For USA  
under controlled conditions on specified govern-  
ment test surfaces of asphalt and concrete. A tire  
marked C may have poor traction performance.  
WARNING  
If you believe that your vehicle has a de-  
fect which could cause a crash or could  
cause injury or death, you should immedi-  
ately inform the National Highway Traffic  
Safety Administration (NHTSA) in addi-  
tion to notifying NISSAN.  
The temperature grade for this tire is es-  
tablished for a tire that is properly in-  
flated and not overloaded. Excessive  
speed, under-inflation, or excessive load-  
ing, either separately or in combination,  
can cause heat build-up and possible tire  
failure.  
WARNING  
The traction grade assigned to this tire is  
based on straight-ahead braking traction  
tests, and does not include acceleration,  
cornering, hydroplaning, or peak traction  
characteristics.  
If NHTSA receives similar complaints, it  
may open an investigation, and if it finds  
that a safety defect exists in a group of  
vehicles, it may order a recall and remedy  
campaign. However, NHTSA cannot be-  
come involved in individual problems be-  
tween you, your dealer, or NISSAN.  
TEMPERATURE A, B AND C  
The temperature grades A (the highest), B, and  
C, representing the tire’s resistance to the gen-  
eration of heat and its ability to dissipate heat  
when tested under controlled conditions on a  
specified indoor laboratory test wheel. Sustained  
high temperature can cause the material of the  
tire to degenerate and reduce tire life, and exces-  
sive temperature can lead to sudden tire failure.  
The grade C corresponds to a level of perfor-  
mance which all passenger car tires must meet  
under the Federal Motor Vehicle Safety Standard  
No. 109. Grades B and A represent higher levels  
of performance on the laboratory test wheel than  
the minimum required by law.  
To contact NHTSA, you may call the Vehicle  
Safety Hotline toll-free at 1-888-327-4236  
(TTY: 1-800-424-9153); go to http://  
or
