TITLE: FMVSR INTERPRETATION

TEXT: This is in reply to your letter of November 27, 1972, requesting what date code should be assigned to tires manufactured during the week of December 31, 1972 through January 6, 1973.

Section 574.5(d) of the Tire Identification and Record Keeping regulation provides in pertinent part that:

"This first two symbols should identify the week of the year using '01' for the first full calendar year in each year. The final section of each year may include not more than six days of the following year." (emphasis added).

Therefore, the last three digits of tires manufactured during the week in question should contain the numerals 532 for the date code.
