DOT, Tire Identification Number (TIN)
U.S. tire regulations require each new tire
manufacturer or tire retreader to mold a TIN
into or onto a sidewall of each tire produced.
The TIN is a unique identifier which facilitates
efforts by tire manufactures to notify pur-
chasers in recall situations or other safety
matters concerning tires and gives purchas-
ers the means to easily identify such tires.
The TIN is comprised of “Manufacturer’s iden-
tification mark”, “Tire size”, “Tire type code”
and “Date of manufacture”.
