TITLE: FMVSS INTERPRETATION

TEXT: This is in response to your letter of January 27, 1976, concerning the rim listing requirements of Federal Motor Vehicle Safety Standards No. 109 and 110.

You wish to designate the 15x5.5JJ rim as permissible for use with tire sizes 225-15 and 230-15. You have requested confirmation of your interpretation that you need merely list the rim in a document that is furnished to your dealers, to any person on request, and in duplicate to the Tire Division of the NHTSA. Your interpretation is correct. Please note, however, that this listing must include dimensional specifications and a diagram of the rim, unless each of the association publications referred to in S4.4.1(b) of Standard No. 109 in which the rim is listed already contains such specifications and diagram.

We hope that you will also ensure that this tire-rim combination is listed in one of those publications as soon as is possible.

Re: FMVSS 109 - New Pneumatic Tires for Passenger Cars FMVSS 110 - Tire Selection and Rims

We are writing to confirm our interpretation of paragraph S.4.4.1 of FMVSS 110 and paragraph S.3 and S.4.4.1 of FMVSS 109.

It is our understanding that in order to add an additional permissible rim width for a tire which is already listed in the tables of FMVSS 109, we need merely include it in a document (such as our Data Book or Technical Bulletin) which is furnished to our dealers and to any person upon request, and in duplicate to the Tire Division of NHTSA.

It is our immediate need to add the 15x5.5JJ rim as a permissible fitment for tire sizes 225-15 and 230-15.

Your prompt reply would be appreciated. Thank you.
