The tire manufacturer is not required to test the tires, but if they are sold in the U.S., they are subject to random testing by the National Highway Traffic Safety Administration (NHTSA), with penalties assessed if the tires fail to be in compliance with federal standards.
Tires found not in compliance with these federal standards will be subject to recall and the manufacturer is subject to civil penalties of up to $6,000 per tire — up to a maximum of $17.4 million for any related series of violations, according to agency documents.
The new codes reflect the agency's policy of replacing the decades-old two-place alphanumeric system with a three-place identity.
The DOT switched out of concern that it would run out of two-place IDs.
In all but a few cases, the DOT added the numeral "1" in front of the existing code to create the new code. Exceptions to this practice are those codes that include "G," "S" or "Q" due to the potential for misreading a G or an S for a 2 or Q for 0, for example.
