Dear Mr. Hudson: This is in reply to your letter of April 3, 1970, to the Director National Highway Safety Bureau, that has been referred to this office.; The type of information requested under items 1 and 2 of your lette can be extracted, within the limitations of the tests conducted, from the enclosed test result summaries. However, it should be recognized that the scope of the Bureau's testing program is such that valid statistical inferences relating to industry-wide rates for tire defects or failures are not possible with the limited data available.; Prior to the adoption of the labeling requirements in Federal Moto Vehicle Safety Standard No. 109, tires could be identified by manufacturer. This was an industry practice, involving the use of serial number systems and was not required by Government regulation nor war the coding used readily available to the general public.; We trust this and the enclosed publication will answer your questions We will be pleased to answer any additional questions.; Thanks you for your interest in the programs of the National Highwa Safety Bureau.; Sincerely, Francis Armstrong, Director, Office of Compliance, Moto Vehicle Programs;
