Bridgestone Commercial Solutions' FT491 All-Position Radial tire 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.
