- EPA SmartWay® verified and CARB-compliant fuel efficiency without sacrificing removal miles means that the Firestone FT491 helps deliver a lower cost per mile. With features such as the patented Defense Groove™ and ULTI-Rib™ designs to combat the initiation and spread of irregular wear, the FT491 is suitable for all-position use, but is designed especially for single- and tandem-axle trailer and dolly applications in long- and regional-haul service.
- The wide footprint spreads load over a larger area, distributing footprint pressure to promote long, smooth wear. The wide design takes a full-size drive cap, which helps extend the life of your casing.
- Ulti-Rib™ design combats the initiation and spread of irregular wear.
- Stress relief sipes fight irregular wear on main ribs by absorbing rib edge stresses in the footprint.
- Flow-through design allows for water evacuation to enhance road grip.
- Thirsty cross-rib sipes improve traction by slicing through water for a solid grip on wet roads.
