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 (Proposed Rule)
SUMMARY: 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.
