Customer Information and Reporting Safety Defects

Uniform Tire Quality Grading System (UTQGS)

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.

 UNIFORM TIRE QUALITY GRADING

Quality grades can be found where applicable on the tire sidewall between tread shoulder 

and maximum section width.
