According to a notice from SEMA, the National Highway Traffic Safety Administration will be in San Francisco today holding a public workshop to gather additional information on how to implement a tire fuel efficiency consumer information program.
In 2010, the NHTSA established the test procedures to be used by tire manufacturers when rating the fuel economy, safety and durability characteristics of replacement tires. However, the agency is still debating how to convey the information to consumers at the point of sale and online.
According to SEMA, NHTSA “is specifically interested in whether to base the fuel efficiency rating on the rolling resistance coefficient or the rolling resistance force. The NHTSA is also interested in reviewing the experiences other countries have had in pursuing similar programs.”
The tire testing and labeling program is supposed to allow consumers to compare ratings for different brands and models of replacement tires, and determine potential tradeoffs between tire fuel efficiency, wet traction and treadwear.
