Tire Identification Number (TIN)
The TIN may be found on one or both sides of the tire; however, the date code may
only be on one side
.
Tires with white sidewalls will have the full TIN, including the date
code, located on the white sidewall side of the tire
.
Look for the TIN on the outboard
side of black sidewall tires as mounted on the vehicle
.
If the TIN is not found on the out-
board side, then you will find it on the inboard side of the tire
.
EXAMPLE:
DOT MA L9 ABCD 0301
DOT
= Department of Transportation
•
This symbol certifies that the tire is in compliance with the U
.
S
.
Department of
Transportation tire safety standards and is approved for highway use
MA
= Code representing the tire manufacturing location (two digits)
L9
= Code representing the tire size (two digits)
ABCD
= Code used by the tire manufacturer (one to four digits)
03
= Number representing the week in which the tire was manufactured (two digits)
•
03 means the 3rd week
01

•
01 means the year 2001
•
Prior to July 2000, tire manufacturers were only required to have one number to repre-

.
Example: 031 could represent the 3rd
week of 1981 or 1991
