Pennsylvania Code › Title 67 - TRANSPORTATION › Part I - Department of Transportation › Subpart A - Vehicle Code Provisions › Article VII - Vehicle Characteristics › Chapter 159 - NEW PNEUMATIC TIRES › Appendix A

Current through Register Vol. 54, No. 28, July 13, 2024
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.
