Roadboss WS001 215/50 R17 98H XL

Tire for winter operation Roadboss WS001 — a universal model that is the result of a systematic approach to winter dynamics. This is a symmetrical platform where each tread zone solves a specific problem, transforming the unpredictability of an icy road into a controlled environment.

Dual contact logic

The shoulder area consists of a high-density matrix of medium-sized blocks with multi-directional lamellas. This structure forms a "claw-like" surface, creating a maximum number of sharp working edges for grip. It is responsible for effective traction when starting, braking on ice, and moving in deep ruts, actively working on the micro-relief. When entering a turn, the load shifts precisely here. These elements, providing minimal deformation, form a stable support platform, ensuring clear feedback through the steering wheel, precise arc guidance, and protecting the tire from accelerated wear in the most loaded points.

Acoustic comfort and resource

The optimized profile of the central tread with a variable radius of curvature performs two key functions. Firstly, it provides a smooth redistribution of pressure in the contact patch when rolling, which directly leads to a reduction in rolling resistance for fuel economy. Secondly, in combination with the calculated step of semi-blocks, this profile disrupts the sound waves generated when contacting the road. The result is a significant reduction in the noise level in the cabin and an increase in acoustic comfort, which is atypical for aggressive winter tires. And this, despite the fact that the surface has a system of spikes that actively participate in maintaining traction properties in icy conditions.

Cryoelastic compound

The heart of the model is a winter compound modified with special plasticizers. Its main property is the preservation of high elasticity and micro-roughness up to extremely low temperatures. This guarantees that the rubber does not become "rigid" in severe frost, but continues to cling to ice and rolled snow, ensuring a short braking distance and predictable handling even in extreme cold. The mixture is also resistant to the effects of reagents and has increased resistance to abrasive wear on cleaned asphalt.

Key features of Roadboss WS001:

- symmetrical system — division into an inner grip zone (middle blocks, lamellas) and an outer stabilization zone (massive blocks) for comprehensive control;
- "intelligent" profile — optimized geometry for reducing rolling resistance, noise, and ensuring even wear;
- compound with a protective function against "curing" — preservation of elasticity and traction properties at extremely low temperatures;
- presence of a Euro-spike system, ensuring stable behavior of the vehicle on slippery roads.
