Firestone FS400 315/70 R22,5 152M Рулевая ось (Рулевая ось)

Like any other truck tire, the Firestone FS400 has a narrow sphere of application. Its primary "target audience" is intercity buses, where this model can be operated on any axle. Despite its unassuming appearance, its design is full of modern technologies and original technical solutions. This allows the tire to demonstrate a number of advantages, from excellent traction on wet roads to a very long service life.

Wear-resistant grooves in the shoulder areas

When developing this tire, special attention was paid to ensuring maximum durability. One of the numerous solutions aimed at solving this problem was special longitudinal grooves located along the edges of the shoulder areas. They prevent premature wear of this part of the tread.

Multifunctional lamellas

In the absence of separate blocks, all the tread edges of this tire are provided with numerous lamellas cut into all its longitudinal ribs. Due to their shape, these tread elements have multifunctionality. In addition to forming the tread edges, they improve resistance to aquaplaning, directing water from the contact patch into one of the nearby drainage grooves. Moreover, these lamellas optimize the distribution of external pressure on it, preventing uneven wear of the tread. In this regard, it is impossible not to mention the original serrated edges of the tread ribs, which also contribute to increasing the tire's service life.
