A new super-wide, low-rolling-resistance trailer tire, the FT125, has been introduced by Double Coin Tires and China Manufacturers Alliance (CMA).
The FT125 is the company's fourth addition to the EPA SmartWay Verified Technology fuel-efficient line, which includes the FR605, FD405, and the FT105. A super-wide drive tire, the FD425, will follow soon..

The new FT125 is said to be engineered with an advanced tread compound and a low-profile design to maximize durability while promoting fuel economy. It boasts a low-rolling-resistance rib-style tread design with an original tread depth of 16/32nds.
It's now available in a 445/50-R22.5 size and has a maximum carrying capacity of 10,300 lb (load index 161).

You might be surprised to know that Double Coin tires have been marketed in the U.S. since 1992. Canadian dealers include Kal Tire.
