Federal Motor Vehicle Safety Standards; New Pneumatic Tires for Motor Vehicles With a GVWR of More Than 4,536 Kilograms (10,000 Pounds) and Motorcycles

요약

This NPRM proposes to upgrade Federal Motor Vehicle Safety Standard (FMVSS) No. 119, which specifies requirements for new truck tires. We propose to amend FMVSS No. 119 to adopt more stringent endurance test requirements and a new high speed test for several heavy load range tires for vehicles with gross vehicle weight rating (GVWR) of more than 4,536 kilograms (10,000 pounds). We are also proposing that FMVSS No. 119 require that the tire sidewall be labeled with the tire's maximum speed rating.
