Pirelli Winter Ice Storm 205/55 R16 91Q

Although the Pirelli Winter Ice Storm non-studded winter tire for passenger cars cannot be considered a novelty, its operational characteristics remain highly relevant against the backdrop of most modern competitors. This was achieved through the use of interesting technical solutions in its design, many of which are applied by the Italian manufacturer today in new models. Among the strengths of this tire, its excellent grip on snowy and wet roads, as well as its "trademark" sports handling, should be particularly noted.

Rigid connections in the central longitudinal rib

The longitudinal rib located in the center of the tread, like the other four similar elements, has a composite structure containing many practically square blocks. They are connected by wide bridges. They give the central rib not only a memorable Z-shaped form but also increased resistance to dynamic deformation. Thus, the impressive appearance of this tread element is combined with its exceptional efficiency. It is expressed in a significant reduction in rolling resistance, improved directional stability, and, in addition, giving the tire's reactions greater speed and accuracy. At the same time, the numerous differently directed faces provide the contact patch with additional grip edges.

Excellent traction properties on snow

The tread pattern of the Pirelli Winter Ice Storm contains a large number of individual blocks of a shape close to a square. In the process of movement, they form a multitude of grip edges. They are most effective when moving on loose snow, providing the tire with excellent traction properties.

Confident behavior on ice and compacted snow

In the absence of studs, this model nevertheless demonstrates fairly confident behavior on compacted snow and ice. It is ensured by the effective work of numerous lamellas cut into all tread blocks. Opening when contacting the road surface, these miniature elements form a multitude of sharp grip edges. Their heights are more than enough to penetrate the water film on the icy surface, thereby ensuring the effective transmission of traction and braking forces.

Optimized rubber compound for winter surfaces

A significant part of the advantages of this model is provided due to the unique properties of the compound from which its tread is made. A characteristic feature of its composition is the increased content of silica and special functional polymers. Carbon-based compounds in the rubber compound give it elasticity and wear resistance, while polymer compounds provide its integrity by increasing tear strength. Due to these features, the tread of this tire improves its grip properties on winter roads, which remain unchanged over a very wide temperature range.

Main features of the Pirelli Winter Ice Storm tire

- a seamless, rigid construction of the central longitudinal rib, thanks to special bridges, improves directional stability, sports-tuned handling, and reduces rolling resistance;
- the block structure of the tread pattern with a large number of individual elements provides good traction properties on snow and wet roads;
- confident behavior on winter roads due to the numerous grip edges formed by wavy lamellas.
