LOUISVILLE -- Three new Firestone brand tires for regional to long-haul use made their debut at the Mid-America Trucking Show.

The new tires - FS591, FD691, and FT491 - meet EPA SmartWay and California Air Resources Board (CARB) fuel efficiency requirements without sacrificing removal miles, according to parent company Bridgestone.

Each tire features patented NanoPro-Tech polymer technology that limits energy loss for improved rolling resistance and optimum fuel efficiency. An innovative sidewall design reduces overall tire weight to improve fuel efficiency without sacrificing durability.

FS591 Steer Radial - Combines low rolling resistance tread and energy-saving casing design to optimize fuel efficiency. The FS591 also features a wide, deep tread and proprietary shoulder design for greater removal mileage and irregular wear resistance. The ULTI-Rib and Defense Side Groove designs promote smooth wear while a continuous shoulder offers long, even wear and lower rolling resistance.

FD691 Drive Radial - Features a continuous shoulder design and high-rigidity tread pattern to promote long, even wear, helping increase tread life and lower rolling resistance. Flow-through design evacuates water to increase road grip. The tire's optimized bead design and proprietary compound found in the sidewall lowers rolling resistance and improves fuel efficiency throughout the lifecycle of the casing.

FT491 All-Position Radial - Features ULTI-Rib and Defense Groove designs to combat the initiation and spread of irregular wear. Sidewall protector ribs help protect the casing from curbing damage and abrasion. Plus, wider tread spreads load over a larger area, distributing footprint pressure to promote long, smooth wear. The wider design also takes a full-size drive cap when retreaded for extended life.
