and manufacturing date A.
DOT (Department of Transportation): tire
symbol : marks that the tire complies with
the requirements of the U.S. Department of
Transportation.
Manufacturer identification code: manufac-
turer 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,

Tire size: identifier = describes the tire size.
Tire type code: tire type code ? can be used
by the manufacturer as a code to describe
