Understanding the Vehicle
Load Identification:
“...blank...” = Absence of any text on
the sidewall of the tire indicates a
Standard Load (SL) tire
XL = Extra Load (or reinforced) tire
LL = Light Load tire
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
outboard side, then you will find it on the
inboard side of the tire.
EXAMPLE: DOT MA L9 ABCD 0320
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 man-
ufacturing location (two digits).
L9 = Code representing the tire size
(two digits).
EXAMPLE: DOT MA L9 ABCD 0320
ABCD = Code used by the tire manu-
facturer (one to four digits).
03 = Number representing the week in
which the tire was manufactured (two
digits). In this case, 03 means the 3rd
week.
20 = Number representing the year in
which the tire was manufactured (two
digits). In this case, 20 means the year
2020.
