SUMMARY:

This document amends Federal Motor Vehicle Safety Standard (FMVSS) No. 109, ''New pneumatic and certain specialty tires,'' in response to a petition for rulemaking from the Tire and Rim Association, to clarify the applicability of the FMVSSs to certain types of tires intended for use on trailers. Based on a review of prior amendments to FMVSS Nos. 109 and 119, ''New pneumatic tires for motor vehicles with a Gross Vehicle Weight Rating (GVWR) of more than 4,536 kilograms (10,000 pounds) and motorcycles.'' NHTSA concludes that it inadvertently made these tires subject to both FMVSS Nos. 109 and 119, when it was the Agency's intent to make them subject only to FMVSS No. 119. This document corrects that error, and also includes nonsubstantive technical corrections to tire and rim regulations.
