The National Highway Traffic Safety Administration is proposing a new sticker for replacement tires that would give buyers more information on which to judge tires. In addition to a wet traction index and tread wear rating, the new proposed stickers would include a fuel efficiency rating. The new rating is based on the tire's rolling resistance, which contributes to the overall efficiency of the vehicle. The new stickers are actually a requirement of the 2007 energy bill and NHTSA has to finalize them by the end of this year. Unfortunately, the sticker should also have some information about the tire's grip characteristics, which affect handling and braking capabilities.
