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.
DOT MA L9 ABCD 0301
DOT = Department of Transportation
•
This symbol certifies that the tire is in compliance with the US 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 = Number representing the year in which the tire was manufactured (two digits)

Tire Terminology And Definitions

B-pillar
Cold Tire Inflation Pressure
Maximum Inflation Pressure
Recommended Cold Tire Inflation Pressure
Tire Placard
Tires with white sidewalls will have the full TIN, includ-
ing the date code, located on the white sidewall side of
the tire.
EXAMPLE:
The vehicle B-pillar is the structural member of the body located behind the front door.
Cold tire inflation pressure is defined as the tire pressure after the vehicle has not been driven for at
least three hours, or driven less than 1 mile (1.6 km) after sitting for a minimum of three hours. Inflation
pressure is measured in units of psi (pounds per square inch) or kPa (kilopascals).
The maximum inflation pressure is the maximum permissible cold tire inflation pressure for this tire. The
maximum inflation pressure is molded into the sidewall.
Vehicle manufacturer's recommended cold tire inflation pressure as shown on the tire placard.
A label permanently attached to the vehicle describing the vehicle's loading capacity, the original equip-
ment tire sizes and the recommended cold tire inflation pressures.
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.
