Designed to carry heavy loads in inter-city bus and on-highway service, the Firestone FS400 delivers excellent performance, exceptional ride quality and high all-season traction. Its deep tread and cross-rib siping ensure a long tread life and superior traction in wet and dry conditions. The tire features shoulder wear protector ribs that suppress irregular wear and special stone-rejector platforms that help prevent the retention of casing-damaging stones to give excellent retreadability. Additional computer-designed features help the FS400 provide a quiet and comfortable ride.
