TITLE: FMVSR INTERPRETATION

TEXT: Mr. (Illegible Word) has asked me to reply to your letter of May 25, 1972, in which you request information regarding tire, wheel and axle capacities as set forth in the Code of Federal Regulations.

I am enclosing Part 567 of the Code which was amended effective January 1, 1972. The amendments require, among other things, that gross axle weight ratings be applied to the certification label. The capacities of the wheel and tire would be calculated into those ratings by our definition of the term. "'Gross axle weight rating' (GAWR) (Illegible Word) the value specified by the vehicle manufacturer as the loaded weight on a single axle measured at the tire-ground interfaces . . . ." (emphasis added).

I am also enclosing the following information that might be of interest to you:

1. Part 566 of Title 49 of the Code of Federal Regulations - Manufacturer Identification

2. Part 568 - Vehicles Manufactured in Two or More Stages

3. Part 573 - Defect Reports

4. Part 574 - Tire Identification

5. Notice of Publications (Illegible Word)

6. National Traffic and Motor Vehicle Safety Act

If you have further questions, I will be pleased to answer them.
