This document responds to petitions for reconsideration of a March 30, 2010 final rule that established test methods to be used by tire manufacturers to generate comparative performance information in order to inform consumers about differences in the fuel efficiency (rolling resistance), safety (wet traction), and durability (treadwear) of replacement passenger car tires. The final rule also established reporting requirements for the generated performance information. In response to the petitions, today's final rule revises certain aspects of the reporting requirements and clarifies others, incorporates by reference a publication cited in the final rule but not included with the other publications incorporated by reference, and clarifies the scope of the program by amending the definition of the term, ``replacement passenger car tires.''
