GT Radial

Four GT Radial commercial tires, including three designed for regional service and one designed for urban delivery, have received SmartWay verification from the EPA.

The four GT Radial tires to obtain SmartWay verification are the GT279 regional steer tire, the GT688 regional driver tire, the GT879 regional all-position tire, and the GT867 all position tire for urban use.

The GT279 features a five straight rib pattern for control and handling, deep tread depth for longer tread life and multiple sipes in the five ribs for better traction and braking. The GT688 has an aggressive open shoulder lug pattern for better traction on wet and dry roads. Central dual serrated ribs contribute to stability and control while the tire’s deep tread depth is designed for a better cost per mile.

The GT879 has a five rib design with wide straight grooves that contribute to better water evacuation. Crossing sipes in the intermediate ribs contribute to traction and longer life, while equal rib distribution provides better resistance to tread scrubbing.

The GT867 has a three-groove tread design developed for urban delivery applications. It has reinforced sidewall protector ribs to help prevent curb damage and a solid shoulder design for enhanced cornering stiffness on the shoulder.

The GT279, GT688 and GT879 tires are SmartWay verified for all of the standard highway sizes – 11R22.5, 11R24.5, 295/75R22.5 and 285/75R24.5. The GT867 is SmartWay verified for the 11R22.5 size .

The EPA has determined that certain low rolling resistance tire models when used on all five axles on line-haul class-8 tractor trailers can reduce NOx emissions and improve fuel consumption by over 3 percent. The EPA has verified that these GT Radial tires achieved the appropriate target values for rolling resistance for their designated axle positions and can be considering low rolling resistance tires.
