In June of 2011 the Sumitomo ST778 SE long haul steer tire earned the EPA's SmartWay certification.That brings the total of Sumitomo low rolling resistant truck tires on the SmartWay Transport Partnership list to three.
"Three very good truck tires have been made even better with the incorporation of low rolling resistance technology," says Richard Purol, vice president of marketing for the TBC Wholesale Group. "SmartWay-verified technologies not only protect the environment, they save fleets money by reducing fuel expense."
The radial tires cover all three truck and trailer axles.
- The Sumitomo ST778se steer tire (see photo) features Flat Contact Technology that minimizes irregular wear by controlling the shape and pressure distribution of the tire footprint.
- The Sumitomo ST938SE drive tire features a new tread pattern concept for strong traction and smooth, even wear.
- The Sumitomo ST710SE trailer tire has shoulder grooves that control migration of irregular wear, and a wide footprint enhances vehicle stability.
The tires are available from TBC Wholesale.
