Posted Wed Sep 17 2008: from Congress, via The National Academies: Fuel-Efficiency Ratings for Tires Proposed http://apocadocs.com/s.pl?1221669934 Congress has ordered the implementation by the end of 2009 of a national consumer information program whose goal will be to produce ratings on passenger tire fuel-efficiency, although regulations will not require tires to be labeled with the ratings. Tires affect vehicle fuel economy through their rolling resistance. As a tire rolls under the weight of a vehicle, its shape changes repeatedly, causing loss of energy in the form of heat, which in turn causes the vehicle to use more fuel to maintain speed. Some of the key variables in a tire's rolling resistance are its tread design and composition, inflation pressure, and level of maintenance.
