Customer Information and Reporting Safety Defects

Uniform Tire Quality Grading System (UTQGS)

Form No. 8S18-EA-03I

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.

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.
