Грузовые шины Doublecoin RR900

The Doublecoin RR900 truck tire is designed for installation on any axle of trucks and buses. This model owes its versatility primarily to the tread pattern, which has high performance in any conditions. Among other key features of this tire, it is worth noting the very low rolling resistance, excellent grip on wet roads, and long service life.

Six rigid longitudinal ribs

The symmetrical non-directional tread pattern of the Doublecoin RR900 model contains six longitudinal ribs, two of which are shoulder areas, and four of which make up its central part. At the same time, each of them is characterized by the complete absence of any breaks, which gives them very high resistance to dynamic deformation. This feature allows the tire to demonstrate several very important operational qualities - high directional stability, responsiveness to handling, and low rolling resistance.

Good traction properties in the longitudinal direction

Despite the absence of separate blocks, the tire's contact patch has a fairly large number of traction edges, including transverse ones. They are formed due to the wavy shape of the longitudinal tread ribs. At the same time, the protrusions on them are arranged with a variable pitch, which makes it possible to significantly reduce the level of resonant noise and vibrations.

Reinforced shoulder areas

In contrast to the central part, the shoulder areas of the tread have more massive dimensions, which gives them rigidity and resistance to dynamic deformation. This design gives the contact patch a rectangular shape, which remains unchanged in any conditions. Thanks to this, a higher resistance of the tread to uneven wear is ensured, which, in turn, led to an increase in the tire's service life.
