DOT, Tire Identification Number (TIN)
U.S. tire regulations prescribe that every tire
manufacturer or retreader must imprint a TIN
in or on the sidewall of every tire produced.
The TIN is a unique identification number. The
TIN makes it easier for tire manufacturers or
retreaders to notify customers of recalls or
other safety-related matters. It makes it pos-
sible for the purchaser to easily identify the
affected tires.
The TIN consists of the manufacturer identi-
fication code ;, tire size =, tire type
code ? and manufacturing date A.
DOT (Department of Transportation): tire
symbol : indicates that the tire complies
with the requirements of the U.S. Department
of Transportation.
Manufacturer identification code: manu-
facturer identification code ; provides
details on the tire manufacturer. New tires
have a code with two symbols. Retreaded
tires have a code with four symbols.
For further information about retreaded tires,
see (
Y
page 310).
Tire size: identifier = describes the tire size.
Tire type code: tire type code ? can be used
by the manufacturer as a code to describe
specific characteristics of the tire.
Date of manufacture: date of manufacture
A provides information about the age of a
tire. The first and second positions represent
the week of manufacture, starting with "01"
for the first calendar week. Positions three
