GT Radial trailer tire

GT Radial introduced its GT979 FS trailer tire, which has received SmartWay verification, to the North American market Thursday in Louisville, Ky.

The addition gives the company a SmartWay truck tire for every axle position. Other GT Radial tires are the GSL213 FS steer tire and GT669+ FS drive tire.

“This is great news for our customers because trailer tires have a significant impact on fuel economy,” said William Estupinan, GITI Tire technical director for the Americas.

He said steer tires account for 15-20 percent of tires’ overall contribution to fuel economy, drive tires 30-40 percent, and trailer tires 40-50 percent.
