Uniform Tire Quality Grading System (UTQGS)
Form No. 8R09-EA-02G
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 vehicle may vary
with respect to grade.
ALL PASSENGER VEHICLE TIRES MUST CONFORM TO THESE GRADES AND
TO ALL OTHER FEDERAL TIRE-SAFETY REQUIREMENTS.

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
The temperature grade for this tire is established for a tire that is properly inflated
and not overloaded. Excessive speed, underinflation, or excessive loading, either
separately or in combination, can cause heat buildup and possible tire failure.
