H. U.S. DOT Tire Identification
Number: 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.
Refer to 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.
