TITLE: FMVSR INTERPRETATION

TEXT: This is to acknowledge your letter of May 19, 1972, regarding tire identification and recordkeeping.

Regulation Part 574 requires a vehicle manufacturer to maintain a record of tires on each vehicle shipped to a dealer and requires that he maintain a record of the name and address of the first purchaser of the vehicle for a period of three years. The purpose, of course, is to enable him to locate tires in the event of a recall. The name and address of the purchaser is provided by the dealer. The manufacturer is not required by the regulation to record each identification number for each tire, but may do so by group or category. There is a strong possibility that all tires on one vehicle will be of the same brand and will have the same identification number. The manner in which a manufacturer chooses to maintain the tire records is optional and the dealer would be expected to cooperate in his system of recording data. It is primarily a matter of agreement between manufacturer and dealer.

In the event the original tires on a vehicle are changed by the dealer prior to sale, he must report the new tire identification numbers and the purchaser's name and address to the manufacturer of the tires sold with the vehicle.

We note that your letter refers to registration of serial number rather than identification number. It is the letter that is subject to the regulation.

We trust this information answers your questions.
