Грузовые шины Doublestar DSR669

The Doublestar DSR669 truck tire is designed for installation on the driving axles of trucks and buses. This model is beneficial not only for its extremely attractive cost, traditional for Chinese tire products, but also for its very high operational characteristics. In particular, this tire is characterized by low rolling resistance and excellent traction properties in the longitudinal direction.

Original Tread Pattern

The distinctive feature of the tread pattern used in this model is the combination of simple and original solutions, thanks to which the Doublestar DSR669 tire is able to demonstrate excellent efficiency in any conditions. It contains five longitudinal ribs, separated from each other by very wide and deep drainage grooves. These wide tread elements, especially the shoulder areas, have practically equal sizes, which ensures a number of important advantages. First of all, this is the optimal distribution of external pressure on the contact patch. This, in turn, led to an increase in carrying capacity and reduced the likelihood of uneven wear. In addition, this feature allowed not only to maximize the contact patch but also to give it a practically rectangular shape, which had a very favorable effect on traction properties.

Multiple Lameles

Another distinctive feature of the tread pattern of this tire is the presence of a large number of lameles, which are located exclusively on the three longitudinal ribs in the central part. During movement, they form numerous traction edges, thanks to which maximum traction properties are ensured in the longitudinal direction. At the same time, most of them are located at a significant angle, which, firstly, reduces rolling resistance, and secondly, reduces the level of resonant noises and vibrations.
