Bridgestone Commercial Solutions is launching the premium Firestone FS507 Plus steer/all-position radial for fuel efficiency and dependability.

The FS507 Plus is approved for use on EPA SmartWay-dedicated equipment and complies with California Air Resources Board rules.

Building on the proven performance of the FS507, the new FS507 Plus adds advanced, fuel-efficient twin-layer tread and sidewall compounding for significantly lower rolling resistance and outstanding fuel economy.

With the top layer of its twin-layer tread formulated for longer wear, the FS507 Plus increases mileage. The lower layer of the tread helps shield the casing from damaging heat for superior life and retreadability.

Shoulder wear protector ribs minimize cupping and step-down wear while stress-relief sipes fight irregular wear and provide hundreds of biting edges to enhance traction.

The new tire uses a deep original tread and proven casing construction with four steel belts and an all-steel body ply.

The FS507 Plus is available in both low profile and 90-series sizes. The low profile tread pattern has five ribs and the 90-series four ribs. Both are available in G and G load ratings.
