TITLE: FMVSS INTERPRETATION

TEXT: This is in response to your February 23, 1976, letter concerning the rim marking requirements of S5.2 of Federal Motor Vehicle Safety Standard No. 120, Tire Selection and Rims for Motor Vehicles Other Than Passenger Cars.

In its present form, S5.2 requires a rim to which the standard applies to be marked with its size designation and, if it is a multi-piece rim, its type designation as well. There is no prohibition on the marking of additional information beyond that which is required. Therefore, the marking of single piece rims with a type designation is permitted.

Please note that, in a notice published on May 6, 1976 (41 FR 18659, Docket No. 71-19, Notice 4), the National Highway Traffic Safety Administration delayed the effective dates of several of the standard's requirements. In particular, the effective date of S5.2, Rim Marking, was delayed until August 1, 1977. A copy of this notice is enclosed for your convenience.

Yours truly,

Enclosure

Re: Interpretation of FMVSS No. 120, S5.2

Dear Mr. Berndt:

This is to request interpretation of Federal Motor Vehicle Safety Standard No. 120, 'Tire Selection and Rims for Vehicles other than Passenger Cars," which was published in the Federal Register of January 23, 1976 as Docket No. 71-19; Notice 3.

In S5.2, it lists the information required to be marked on each rim on and after August 1, 1976. As we understand it, this requirement does not prohibit marking of additional information on rims. For example, although S5.2(6) requires that each rim be marked with information of the rim size designation, and, in the case of multipiece rims, the rim type designation, we believe that single piece rims should also be marked with the rim type designation, such as the type of flange denoted as J, JJ, etc., for reasons of vehicle safety.

We would appreciate your informing us of the correct interpretation at your earliest convenience.

Very truly yours,

D. KIWANO FOR

K. Nakajima -- Director/General Manager, Factory Representative Office
