TITLE: FMVSS INTERPRETATION

TEXT: This is in reply to your letter of January 21, 1969, requesting the "actual state of affairs" concerning States requiring a V-1 marking on tires.

You are correct in your understanding that the Federal tire standard (No. 109 preempts or supersedes any State regulation applicable to the same aspect of performance. The Federal tire standard does not require tires to be marked with the "V-1" symbol. However, it does not prohibit such marking. Our understanding is that American tire manufacturers have continued marking their product with "V-1" symbol although not required to do so by the Federal standard.
