General S581, S371, D660 and ST250 truck tires were recently verified by SmartWay as low rolling resistance tires. The General S581 long-haul steer tire features an 18/32-inch five rib tread design, for wet traction and lateral stability. The General S371 long-haul steer and drive tire has 20/32-inch tread depth. Its tread compound provides long highway miles while resisting cuts and tears in off-highway use. The D660 is a long-haul drive tire with 30/32-inch tread depth and a closed shoulder tread design for long, even wear. The ST250, a long-haul trailer tire, features 13/32-inch tread depth, a stone ejection system and the patented visual alignment indicators to alert drivers of tracking problems.
Tires verified by the EPA for lower rolling resistance can provide a reduction in NOx emissions and an estimated fuel savings of 3 percent or greater, relative to the "best selling" new tires for line haul trucks, when used on all five axles on long-haul Class 8 trucks.
