The National Highway Traffic Safety Administration on Wednesday, Sept. 29, issued a notice of proposed rulemaking 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 of more than 10,000 pounds.
The NPRM would upgrade Federal Motor Vehicle Safety Standard 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.
