TITLE: FMVSS INTERPRETATION

TEXT: This is in reference to a question that has been raised in telephone conversations, by Monsanto, as to whether the NHTSA allows a manufacturer of newly developed tires to run them on the public roads before they are certified as conforming to Standard 109.

The answer is no. We have, to the best of our knowledge, allowed no exception to the requirement that all tires to which a motor vehicle safety standard is applicable must conform to the standard and be certified as such.
