Uniform Tire Quality Grading System (UTQGS)
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.
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.
