Uniform Tire Quality Grading System (UTQGS)
This information relates to the tire grading system developed by the U.S. National
Highway Traffic Safety Administration for grading tires by tread wear, traction, and
temperature performance.
qTread Wear
The tread wear grade is a comparative rating based on the wear rate of the tire when tested
under controlled conditions on a specified government test course.
For example, a tire graded 150 would wear one-and-a-half times as well on the government
course as a tire graded 100.
The relative performance of tires depends upon the actual conditions of their use, however,
and may depart significantly from the norm because of variations in driving habits, service
practices and differences in road characteristics and climate.
qTraction-AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B, and C. These 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.
WARNING
The traction grade assigned to this tire is based on braking (straight ahead) traction
tests and does not include acceleration cornering (turning), hydroplaning, or peak
traction characteristics.
qTemperature-A, B, C
The temperature grades A (the highest), B, and C, represent the tire's resistance to the
generation 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 excessive temperatures can lead to sudden tire failure.
Grade C corresponds to a level of performance which all passenger vehicle 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.

WARNING
Keep your vehicle's tires properly inflated and not overloaded:Driving with improperly inflated or overloaded tires is dangerous. Excessive speed,
underinflation, or excessive loading, either separately or in combination, can cause
heat buildup and possible tire failure. The temperature grade for this tire is
established for a tire that is properly inflated and not overloaded.
These grades will be added to the sidewalls of passenger vehicle tires over the next several
years according to a schedule established by the NHTSA and the tire manufacturers.
The grade of tires available as standard or optional equipment on Mazda vehicles may vary
with respect to grade.
ALL PASSENGER VEHICLE TIRES MUST CONFORM TO THESE GRADES AND
TO ALL OTHER FEDERAL TIRE-SAFETY REQUIREMENTS.
q Uniform Tire Quality Grading
Quality grades can be found where applicable on the tire sidewall between tread shoulder
and maximum section width.
For example:
Treadwear 200 Traction AA Temperature A
TREADWEAR 200 TRACTION AA
TEMPERATURE A

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 affect 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 Certification 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 inflation
pressure.
Never overload the vehicle and always observe the vehicle's weight ratings from the
vehicle's Safety Certification and Tire and Load Information labels.

Reporting Safety Defects (U.S.A.)
If you believe that your vehicle has a defect which could cause a crash or could
cause injury or death, you should immediately inform the National Highway
Traffic Safety Administration (NHTSA) in addition to notifying Mazda Motor
Corporation (Your Mazda Importer/Distributor).
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 become involved in individual
problems between you, your dealer, or Mazda Motor Corporation (Your Mazda
Importer/Distributor).
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://www.safercar.gov; or write to:
Administrator, NHTSA, 1200 New Jersey Avenue, SE., Washington, DC,
20590. You can also obtain other information about motor vehicle safety from
http://www.safercar.gov.
