Letter rating Speed rating - mph (km/h)

W 168 mph (270 km/h)

Y 186 mph (299 km/h)

Note: For tires with a maximum speed capability over 149 mph

(240 km/h), tire manufacturers sometimes use the letters ZR. For

those with a maximum speed capability over 186 mph (299 km/h), tire

manufacturers always use the letters ZR.

H. U.S. DOT Tire Identification Number (TIN): This begins with the

letters DOT and indicates that the tire meets all federal standards. The

next two numbers or letters are the plant code designating where it was

manufactured, the next two are the tire size code and the last four

numbers represent the week and year the tire was built. For example,

the numbers 317 mean the 31st week of 1997. After 2000 the numbers

go to four digits. For example, 2501 means the 25th week of 2001. The

numbers in between are identification codes used for traceability. This

information is used to contact customers if a tire defect requires a recall.

I. M+S or M/S: Mud and Snow, or

AT: All Terrain, or

AS: All Season.

J. Tire Ply Composition and Material Used: Indicates the number of

plies or the number of layers of rubber-coated fabric in the tire tread and

sidewall. Tire manufacturers also must indicate the ply materials in the

tire and the sidewall, which include steel, nylon, polyester, and others.

K. Maximum Load: Indicates the maximum load in kilograms and

pounds that can be carried by the tire. See the Safety Compliance

Certification Label (affixed to either the door hinge pillar, door-latch

post, or the door edge that meets the door-latch post, next to the

driver’s seating position), for the correct tire pressure for your vehicle.

L. Treadwear, Traction and Temperature Grades

• 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

⁄

) times as well on the government

course as a tire graded 100.

• Traction: 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.
