The Westlake CR856 cargo tire was specially designed for light and medium-duty trucks, as well as buses, operated mainly in urban conditions. In addition, the wide range of applications of this model is ensured by the possibility of its use on any axles of the above categories of commercial equipment.
Four longitudinal ribs
Unlike most other tire products of similar purpose, this model has a symmetrical non-directional tread pattern with a minimal number of individual elements. This design feature cannot be considered a disadvantage, since thanks to such a design, the tire has been given a number of important advantages. The main one, perhaps, is very low rolling resistance, which provides it with excellent fuel efficiency.
In addition, the reduction in the number of individual tread elements allowed Chinese tire manufacturers to make them as large as possible. In addition to the increased contact patch size, this design feature gave them increased resistance to dynamic deformation, which in turn led to improved directional stability.
Excellent load capacity
Another advantage of the 4-rib tread pattern design of this model was the optimization of external pressure distribution over the contact patch achieved through this. As a result, the tire demonstrates not only excellent load capacity but also resistance to uneven tread wear, which significantly increased its service life.
Excellent traction on wet roads
The next undisputed advantage of this tire is its traction properties on wet roads. They are mainly provided by the zigzag shape of the drainage grooves separating the tread ribs from each other. During movement, these elements not only drain water from the contact patch but also provide it with a large number of traction edges.
Key features of the WestLake CR856 tire
- a universal model that is equally well suited for all axles of not only light and medium-duty trucks but also buses;
- the minimal number of individual tread elements made it possible to make them very massive, which led to an increase in the contact patch size;
- the rigid design of the four longitudinal ribs reduces rolling resistance, optimizes the distribution of external pressure over the contact patch, and increases directional stability.
