All-season tire for SUVs Nexen Roadian AT Pro RA8 is one of the most popular models of the well-known South Korean manufacturer, which offers it all over the world, except for those regions where there is no snow in winter. Its key feature is a very wide range of applications, provided by good performance on any type of coverage, regardless of weather conditions, although with some limitations, significantly leveled due to the use of modern technologies and materials.

Dual blocks in the central part of the tread

This model is equipped with a tread with an open design, consisting of many individual elements. In the central part, the blocks have a dual structure, consisting of two adjacent "halves". This feature improves traction and coupling properties, primarily on slippery surfaces, gives the tire softness on uneven roads, and due to the longitudinal arrangement, reduces rolling resistance. At the same time, it is impossible not to note the complex geometric shape of the blocks. Their numerous faces provide a contact patch with many additional coupling edges.

Handling and traction on snow and wet roads

A significant part of the above-mentioned versatility of this model is provided due to the numerous lamellas located throughout the tread, in all its blocks. These miniature elements, when in contact with the road, open up and form several hundred additional coupling edges. This allows the tire to demonstrate very confident behavior, primarily on wet and snowy roads.

In addition, it is impossible not to note the wavy shape of the lamellas. It allows their walls to remain stationary relative to each other, which limits the mobility of the blocks and, as a consequence, improves handling on asphalt.

Zigzag edge in the center

Like the rest of the tread, the central longitudinal edge consists of many individual blocks. However, they are arranged in such a way that they give it an original zigzag shape. Thanks to this, the central edge can perform several important functions while driving. First of all, this is stability and reliability at high speed, as well as reduced rolling resistance. At the same time, the use of such a configuration of the edge provides a contact patch with many additional transverse coupling edges, which, in turn, significantly improves longitudinal traction and coupling properties.

Multifunctional blocks in the shoulder zones

The distinctive feature of the design of the shoulder zones of the tread of this tire is the shape and size of the blocks located here. They are distinguished by a quadrangular shape and significant width, while a significant part of them is located on the sidewalls. This allows them to perform several tasks at once. The main ones are providing maximum stability when passing turns, optimizing the distribution of external pressure on the contact patch, increasing stability of behavior and coupling when accelerating and braking. The part of the blocks located on the outside improves the passability on dirt roads.
