The Firestone FS821 is a highway terrain, all season tire made for commercial vehicles. It was designed for use on all axle positions. Its all-steel casing and the special cap/base compounding keep the optimal tire shape under load pressure. Sine the tire does not deform, it can securely carry and withstand heavy loads with ease.
The tire ensures exceptional all season traction. The ribbed tread design, with the multiple biting edges, and the all season compound increase the year-round performance. The tread elements firmly grip the road surface, while the compound keeps the rubber flexible. Circumferential grooves disperse water and slush from the footprint, combating hydroplaning.
The Firestone FS821 upgrades the usability. The special compound, the stabilized tread design, and the reinforced internal structure enhance the tread life by working together. Stronger compound elements minimize the treadwear rate, while it also resists tread damage. The optimal footprint’s even pressure circulation avoids irregular wear as well. The special stone ejecting platforms eliminate rocks from the footprint. This effectively combats stone retention. The combination of these improvements significantly boosts the tire’s overall service life.
