The Firestone FS422 summer tire is designed for the steering axle of long-haul trucks. This model stands out for its excellent directional stability, wet traction, fuel efficiency, and long service life.
Handling Comfort
This model significantly improves the handling comfort of a truck. This is largely due to the design of the tread pattern, which consists of five solid longitudinal ribs, each of a different size. The shoulder areas are much wider, providing higher resistance to deformation and ensuring fast and precise transmission of lateral acceleration forces.
Resistance to Irregular Wear
The absence of breaks in the tread ribs provides another advantage of the tire. This design ensures a very even distribution of the vehicle's external weight across the tire's contact patch, reducing the risk of irregular wear caused by lateral acceleration forces and abrasive road surfaces. This significantly extends the life of the tread.
Wet Traction
All tread ribs feature numerous lateral grooves with a polygonal shape, providing the contact patch with an even larger number of sharp edges. These edges penetrate through the water film, allowing the tire to effectively grip the road surface.
Extended Service Life
The tire features a full-metal carcass, which, in addition to improving load capacity and handling, provides a significant increase in tire life. When worn, the tire can be retreaded.
