Developed for daily driving on snowy and mixed roads, the Three-A WINTER PRO model combines key solutions. Engineers have achieved high directional stability, predictable handling, short braking distance on snow, reduced fuel consumption, and extended mileage.
Geometry and Multi-Block Division
The non-directional tread pattern is executed in an asymmetric form. The key element is a multitude of small but rigid blocks arranged with a variable pitch. This architecture solves three problems at once:
- excellent grip on loose and rolled snow due to the large number of gripping edges;
- fast self-cleaning of drainage channels;
- minimized rolling resistance due to optimized stress distribution in the contact patch.
This configuration reduces uneven wear and increases directional stability at high speeds.
Ice Traction Engineering
A particular pride of the developers is the array of three-dimensional lamellas. Unlike flat elements, their walls have a complex wavy shape. This gives two important effects:
- when braking and accelerating, the differently directed faces create additional grip;
- under lateral loads, the lamella walls lock each other, preventing excessive mobility of the elements, ensuring clear, predictable steering control.
Key Features of Three-A WINTER PRO:
- installation on most passenger cars in the winter period;
- fine-block structure of the tread ensures confident acceleration and stability on any snow-covered roads;
- increased density of three-dimensional lamellas improves traction on ice and wet snow, maintaining block stiffness during maneuvers;
- special block geometry reduces rolling resistance and abrasive wear, while enhancing drainage for stable handling.
