The U.S. Environmental Protection Agency (EPA) has announced the first verifications of low rolling resistance retread tire products under the performance requirements announced in June 2012. Verified drive and trailer retreads are both available. More information about the SmartWay program, low rolling resistance tires and EPA-verified retreads can be found at: http://www.epa.gov/otaq/smartway/technology/tires.htm.
EPA estimates that using verified low rolling resistance tires can improve fuel consumption by three percent when used in all axle positions on line-haul class-8 tractor trailers. Verified retreads, when used in the drive and trailer axle positions in combination with EPA-verified steer tires, can reduce fuel consumption by three percent relative to the most common retreads.
