Current through Register Vol. 54, No. 50, December 14, 2024

Appendix A

The following tables list tire sizes and tire constructions with proper load and inflation values. The tables group tires of related constructions and load-inflation values. Persons requesting the addition of new tire sizes to the tables or the addition of tables for new tire constructions may, when the additions requested are compatible with existent groupings, or when adequate justification for new tables exists, submit five copies of information and data supporting the request to the Secretary of Transportation, Attention: Motor Vehicle Programs, National Highway Traffic Safety Administration, U.S. Department of Transportation, Washington, D.C. 20590.

The information should contain the following:

(1) The tire size designation, and a statement either that the tire is an addition to a category of tires listed in the tables or that it is in a new category for which a table has not been developed.

(2) The tire dimensions, including aspect ratio, size factor, section width, overall width and test rim size.

(3) The load-inflation schedule of the tire.

(4) A statement as to whether the tire size designation and load-inflation schedule has been coordinated with the Tire and Rim Association, the European Tyre and Rim Technical Organisation, the society of Manufacturers and Traders Limited, the Japan Automobile Tire Manufacturers Association, the Deutsche Industrie Norm and the Scandinavian Tire and Rim Organisation.

(5) Copies of test data sheets showing test conditions, results and conclusions obtained for individual tests specified in this chapter.

(6) Justification for the additional tire sizes.
