Satoya SF-042 315/80 R22,5 156/152L PR20 (Рулевая ось)

The Satoya SF-042 truck tire, designed for the steering axle of highway trucks, favorably stands out against the background of its numerous analogs from competing brands. And it's not just the attractive cost, traditional for tire products from China. First and foremost, this model is distinguished by excellent traction properties on wet roads, fuel efficiency, and a long service life, making its purchase economically advantageous.

5-rib design of the tread pattern

Since this model was initially developed for operation on the steering axle of highway trucks, it's no surprise that its symmetrical non-directional tread pattern features five longitudinal ribs. This design gives the tire a whole range of operational qualities that are extremely important, considering the specific conditions of its use. First and foremost, this is reduced rolling resistance, excellent directional stability when driving at high speeds, and maneuverability. These properties were achieved due to the rigid construction of all five longitudinal tread ribs, which, thanks to this, possess excellent resistance to dynamic deformation.

High braking efficiency on wet roads

Despite the absence of numerous tread blocks, the contact patch has a large number of traction edges. They are formed during movement due to the Z-shaped lamellas, located on the even tread ribs, which open when in contact with the road surface.

Reinforced shoulder areas and central longitudinal rib

One of the distinctive features of the tread pattern of this tire is the reinforced design of the shoulder areas and the central tread rib. Each of these tread elements is characterized by increased stiffness. In combination with their location, this contributes to a significant improvement in a number of important operational characteristics of the Satoya SF-042 truck tire. The main one is the optimization of the distribution of external pressure over the contact patch, which, in turn, led to an increase in load capacity and resistance to uneven wear of the tread.

In addition, it is impossible not to note the increased size of the contact patch, the shape of which, due to this design feature, remains unchanged under any road conditions. This allows the tire to demonstrate reliable and very stable traction on dry roads.

Main features of the Satoya SF-042 tire

- the tire was developed taking into account the specific operating conditions on the steering axle of trucks;
- five rigid longitudinal ribs provide excellent directional stability when driving at high speeds, maneuverability, and low rolling resistance;
- the reinforced design of the central longitudinal rib and shoulder areas optimizes the distribution of external pressure over the contact patch, which, in turn, improves load capacity and resistance to uneven wear of the tread;
- the optimized design of the symmetrical non-directional tread pattern provides excellent traction properties under any road and weather conditions;
- excellent resistance to aquaplaning due to four very voluminous drainage grooves;
- a short braking distance on wet roads is achieved due to numerous transverse traction edges formed by special Z-shaped lamellas.
