Firestone FS561. FEATURES AND BENEFITS: Longer lasting tread life; Enhanced durability; Fuel efficient performance; . OVERVIEW: The Firestone FS561 is a highway terrain, all season tire manufactured for commercial vehicles. It was made to be mounted on the steer axle.The model guarantees a lengthened tread life. The ribbed tread design enhances the model's even pressure distribution. It keeps the tire's contact with the road surface at all times to promote a slow, even tread wear. The ribbed design and the solid shoulder ribs keep the tire's road contact and equally spread out the forces of acceleration, cornering and braking along the tread area. This allows the tire to improve the tread life by avoiding irregular tread wear formations across the tread area. The extended tread life upgrades the tire's usability significantly.The tire's durability is ensured throughout the tire's lifetime. The durable tire compound and tread design's self-cleaning nature avoids damage to the tire's casing. The stronger compound prevents punctures, cuts and chipping, while the maintained clean footprint avoids stone retention from harming the tire. The strengthened internal steel belt structure keeps the optimal tire shape under the driving and load pressure affecting the drive. The tire's shape does not deform under the pressure affecting the model, which enhances its load carrying durability and performing capability.The FS561 offers a fuel efficient performance. The ribbed tread design's maintained road contact eases the driving pressure off the model, while keeping its excellent all weather traction. This successfully decreases the tire's rolling resistance, which is the pressure affecting the tire that determines the amount of energy needed for the vehicle to maintain the tire's motion. The reduced rolling resistance, in turn, lessens the vehicle's fuel consumption and CO2 emissions. In this manner, the model provides a fuel efficient and environmentally friendly driving experience. Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
