TIRE LABELING
Federal law requires tire manufacturers to
place standardized information on the
sidewall of all tires. This information
identifies and describes the fundamental
characteristicsof the tire and also provides
the tire identification number (TIN) for
safety standard certification. The TIN can
be used to identify the tire in case of a
recall.
