The National Highway Traffic Safety Administration has extended the comment period for its proposal to upgrade the Federal Motor Vehicle Safety Standard that applies to new pneumatic tires for use on vehicles with a gross vehicle weight rating greater than 10,000 pounds and motorcycles.
In its Sept. 29 proposal, NHTSA established a deadline for the submission of written comments of Nov. 29. In light of a petition to extend the comment period 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 to Dec. 29.
NHTSA’s notice of proposed rulemaking would adopt more stringent endurance test requirements and a new high speed test for several heavy load range tires for vehicles with a GVWR of more than 10,000 pounds. The NPRM would upgrade FMVSS No. 119, which specifies requirements for new truck tires. NHTSA also is proposing that FMVSS No. 119 require that the tire sidewall be labeled with the tire’s maximum speed rating.
The docket number is NHTSA-2010-0132.
