Extension of comment period.


NHTSA has received a petition asking the agency to extend the comment period for its proposal to upgrade the Federal motor vehicle safety standard (FMVSS) that applies to new pneumatic tires for use on vehicles with a gross vehicle weight rating (GVWR) greater than 10,000 pounds and motorcycles. In the proposal, NHTSA established a deadline for the submission of written comments of November 29, 2010. In light of that petition and the need to ensure that all interested parties have a sufficient amount of time to fully develop their comments, the agency is extending the deadline for the submission of written comments by 30 days.


Written comments must be received by December 29, 2010.

NHTSA issued a notice of proposed rulemaking (NPRM) proposing to upgrade FMVSS No. 119 (49 CFR 571.119), which applies to new pneumatic tires for vehicles with a GVWR greater than 10,000 pounds and motorcycles. The NPRM was published on September 29, 2010 (75 FR 60037, Docket No. NHTSA-2010-0132). In the NPRM, among other matters, NHTSA proposed to amend FMVSS No. 119 to adopt a more stringent endurance test and a new high speed test for heavy vehicle tires with a load range of F, G, H, J, and L.

The Rubber Manufacturers Association (RMA), which represents manufacturers of finished rubber products, including tire manufacturers, has petitioned for an extension of the comment period on the NPRM. RMA said that it is requesting a 30-day extension so that its members can complete all of their additional testing to evaluate the more stringent endurance test proposed by the agency and to develop new data to demonstrate differences in outcomes with tire break-in versus no break-in for the new proposed high speed test. RMA indicated that it also intends to supplement its earlier test data submitted to the agency on April 14, 2009. RMA believes that the earlier data set submitted to the docket, combined with additional new data, will assist NHTSA in evaluating RMA's comments and arriving at a final rule. RMA maintains that its members require several weeks to complete even a small test program of the 47-hour endurance test. Therefore, RMA indicates that it is not possible for its members to complete all of their additional testing and have it ready for submittal by November 29, 2010.

In considering the extension request, NHTSA weighed the complexity and importance of this rulemaking and the basis for the request. We have decided there is good cause to grant the petition and extend the comment period 30 days. The extension is in the public interest since it will provide the public additional time to prepare and submit useful technical information that should benefit agency decision-making in this rulemaking action. Accordingly, NHTSA extends the period for the submission of written comments in this proceeding to December 29, 2010.
