Letter rating Speed rating - mph (km/h)
V 149 mph (240 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.
8. 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.
9. M+S or M/S: Mud and Snow, or
AT: All Terrain, or
AS: All Season.
10. 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.
11. Maximum Load: Indicates the maximum load in kilograms and
pounds that can be carried by the tire. Refer to the Safety
Compliance Certification Label, which is located on the B-Pillar or
the edge of the driver’s door, for the correct tire pressure for your
vehicle.
12. 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
1 ⁄
2
) 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
