Bridgestone Americas is launching the new Firestone FS507 Plus, steer/all-position radial that delivers "superior fuel efficiency and outstanding dependability," according to the tiremaker.
The SmartWay verified FS507 Plus also meets California Air Resources Board (CARB) rules.
“Fleets who rely on Firestone’s superior cost per mile and value can run SmartWay-verified Firestone tires on every wheel position. Using the new FS507 Plus steer, in combination with the FD695 Plus drive and FT455 Plus trailer tires, offers some of the best fuel efficiency in the industry,” said Bert Jones, manager of product marketing.
The Firestone FS507 Plus features a fuel-efficient twin-layer tread and sidewall compounding that Bridgestone claims “significantly” lowers rolling resistance and provides for longer wear. The lower layer of the tread protects the casing from heat damage, and shoulder wear protector ribs reduce cupping and step-down wear while stress-relief sipes fight irregular wear and provide hundreds of biting edges to enhance traction, Bridgestone said. The FS507 Plus also has four steel belts and an all-steel body ply.
According to Bridgestone, the tire is available in low profile and 90-series sizes, though specific sizes were not offered. The low profile tread pattern has five ribs and the 90-series four ribs. Both are available in G and H load ratings.
