Firestone FS422+ 315/80 R22,5 156/154M (Рулевая ось)

The commercial tire Firestone FS422+ is installed on the steering and trailer axles of trucks. It is adapted for operation on high-speed highways. In motion, it is characterized by directional stability, improved traction on wet surfaces, fuel efficiency, and increased service life.

The tread pattern is made in a closed design, featuring five solid longitudinal ribs. This solution reduces rolling resistance, prevents uneven wear, ensures precision handling and stability of traction on high speed and during maneuvering. The effectiveness of the tire on wet surfaces is ensured by the use of a special rubber compound in the tread manufacturing, which is elastic at low temperatures, as well as numerous edges formed by lamellas.

Main features:

- the tread pattern with rigid longitudinal ribs provides directional stability and handling precision at high speed, reduces rolling resistance and uneven wear;
- high deceleration intensity on wet surface due to the multitude of transverse lamellas;
- enlarged drainage grooves reduce the risk of aquaplaning.
