hdghg -- Tractor-Trailer Greenhouse Gas Regulation Clarification of Low Rolling Resistance Tire Requirements for 2010 Model Year and Older Tractors
Posted: 02 Oct 2012 13:40:37
The California Air Resources Board has issued Advisory Mail-Out MSC# 12-19 to explain how the low rolling resistance tire requirements for 2010 and older model year tractors will be implemented. The Advisory notifies owners of 2010 and older affected tractors that these tractors must comply with the January 1, 2013, tires deadline by using SmartWay verified tires (new or retread). However, the Advisory also clarifies that owners may continue to use non-SmartWay verified tires manufactured before January 1, 2013, until the end of the tire’s useful tread life, or until January 1, 2015, whichever comes first. Any new or retreaded tire manufactured and installed on an affected tractor after January 1, 2013, must be a SmartWay verified tire. After January 1, 2015, all tires on affected tractors must be SmartWay verified. Background The Tractor-Trailer GHG Regulation (regulation) applies to 53-foot or longer dry van or refrigerated van trailers (box-type trailers) and the tractors that pull them on California highways. The regulation requires tractor-trailers operating in California to use tractors and box-type trailers that utilize certain aerodynamic equipment and low rolling resistance tires, as verified by the U.S. EPA SmartWay program, to meet specified fuel efficiency improvements. The regulation requires owners of affected tractors to meet the following tire requirements: • 2011 model year and newer affected tractors (sleeper cabs and day cabs) must use SmartWay verified low rolling resistance new tires or SmartWay verified retread tires beginning in 2010. • 2010 model year and older affected tractors must use SmartWay verified low rolling resistance new tires or SmartWay verified retread tires by January 1, 2013. The Advisory clarifies that 2010 model year and older affected tractors using tires that are not SmartWay verified and were manufactured or retreaded prior to January 1, 2013 (as determined by the U.S. Department of Transportation “DOT” date stamp on the sidewall) may continue to use those tires until the end of their useful tread life, or until January 1, 2015, whichever comes first. After January 1, 2013, any tire on an affected tractor that must be replaced or retreaded must be a SmartWay verified low rolling resistance tire.
