TITLE: FMVSS INTERPRETATION

TEXT: Thank you for your letter of October 31, 1969 requesting information about the Federal Motor Vehicle Safety Standards and their applicability to wheels manufactured by Pacer. We have enclosed a copy of the April, 1969, edition of the Federal Motor Vehicle Safety Standards, along with amendments relevant to your inquiry.

You have requested information as to how you can comply with Standards No. 109 and 110. These Standards, as you will notice, are applicable to new passenger car tires add to wheels and tires mounted on new passenger cars, so that if a wheel manufactured by Pacer is placed on a passenger car before the car is sold to the first purchaser, the wheel and the tire must conform to the requirements of Standards No. 109 and 110. To comply the tire and rim must meet the performance requirements of Standard 109, and the rim must be able to retain a deflated tire during a stop from 60 miles per hour, as required by paragraph S4.4.1(b) of Standard No. 110. There are no other requirements applicable to wheels and rims as such.

The National Highway Safety Bureau issues no certificate of compliance, although it maintains surveillance over product safely through its own testing program. The Gregon manufacturer to whom you refer may have requested the Bureau's opinion as to whether a particular wheel design would violate Standard No. 211, a standard applicable to wheel nuts, wheel discs and hub caps as items of motor vehicle equipment which prohibits certain tyres of hazardous projections on wheels. In response to such requests, the Bureau has occasionally issued interpretations of Standard No. 211, but these are in no way equivalent to a certificate of compliance.

I trust this information will be helpful to you. Should you have additional questions, please advise us and we will try to provide further clarification.
