Double Coin's RR680 tire has met the requirements for the U.S. Environmental Protection Agency’s SmartWay Technology Program.

EPA has verified that the RR680 has met the low rolling resistance tire performance criteria for new tires in both the steer and drive positions. Since 2004, EPA’s SmartWay Technology Program tests and verifies the performance of vehicles, technologies and equipment that have the potential to lower greenhouse gases and other air pollutants from freight transport.

In addition to the RR680, the OptiGreen Series includes Double Coin’s FR605, FD405, FT105, FT125, and the FD425.
