China Manufacturers Alliance L.L.C.'s Double Coin RR680 tire has met the requirements for the U.S. Environmental Protection Agency's SmartWay Technology Program.

CMA said the RR680 has met the EPA low rolling resistance tire performance criteria for new tires in both the steer and drive positions.

"Double Coin's RR680 was designed for today's transportation requirements and joins five other Double Coin fuel efficient models included in the OptiGreen Series line," said Aaron C. Murphy, vice president of CMA.

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