Firestone FS507 Plus steer/all-position tire

Tires and wheels | November 10, 2011

Firestone’s FS507 Plus steer/all-position radial tire is a remake of the FS507, with an added twin-layer tread and sidewall compounding for lower rolling resistance and improved fuel economy, the company says. The top layer of its twin-layer tread promotes longer wear, while the lower layer helps shield the casing from damaging heat. Shoulder wear protector ribs minimize supping and step-down wear, and stress-relief sipes provide biting edges that enhance traction. The FS507 Plus is approved for use on Environmental Protection Agency and SmartWay-certified equipment and complies with California Air Resources Board rules.
