INFORMATION ABOUT UNIFORM TIRE QUALITY GRADING

New vehicles are fitted with tires

that have a rating on them called

Tire Quality Grades. The 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

These Tire Quality Grades are determined by standards that the United

States Department of Transportation has set.
Tire Quality Grades apply to new pneumatic tires for use on passenger

cars. They do not apply to deep tread, winter-type snow tires,

space-saver or temporary use spare tires, tires with nominal rim

diameters of 10 to 12 inches or limited production tires as defined in

Title 49 Code of Federal Regulations Part 575.104(c)(2).

U.S. Department of Transportation-Tire quality grades:

The U.S.

Department of Transportation requires Mazda to give you the following

information about tire grades exactly as the government has written it.

Treadwear

The treadwear 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 one-half (1 1/2) 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 due to variations in driving habits, service practices, and

differences in road characteristics and climates.

Traction AA A B C

The traction grades, from highest to lowest are AA, A, B, and C. The

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.

NOTE:

The traction grade assigned to this tire is based on

straight-ahead braking traction tests, and does not include acceleration,

cornering, hydroplaning or peak traction characteristics.
