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
purchasers in recall situations or other safety
matters concerning tires and gives
purchasers the means to easily identify such
tires.
The TIN is comprised of "Manufacturer's
identification mark", "Tire size", "Tire type
code" and "Date of manufacture".
