Bridgestone America’s latest ultra-wide-base tires, the Greatec M835A Ecopia tire for the drive position and the Greatec R197 Ecopia tire for the trailer position, are designed for use on tandem-axle applications in long-haul service. The tires have a high-rigidity tread pattern to help enhance tread life, overall even wear and low rolling resistance; an optimized shoulder design for even wear balance across the tire footprint; Bridgestone America’s proprietary NanoPro-Tech compound to help limit energy loss for improved rolling resistance; the company’s Fuel Saver Sidewall technology to help absorb excess energy and conserve fuel, both when new and retreaded; a patented Waved Belt design to help reduce casing growth and maintain a stable footprint; a patented Turn-In Ply design that addresses ply-end stress; and stone rejector platforms that combat capture and retention of casing-damaging stones. The tires are compatible with Bandag FuelTech retreads and are available in size 445/50R22.5.
