When the temperature drops below zero and the road turns into a series of icy stretches, the driver faces a tough choice: overpay for premium tires or find a budget solution that really works. Unistar Ice Protection S — an affordable studded tire for passenger cars. The model features a directed V-shaped tread, enhanced stud fixation, and a frost-resistant compound.
V-shaped scheme
Tread according to the directed scheme. Multiple drainage grooves are oriented at an angle to the direction of movement, actively "ejecting" water and snow mass from the contact patch. The open design of the "shoulders" provides additional paths for moisture removal. The V-shape also improves the car's self-alignment on slippery surfaces. The result is resistance to hydroplaning and slushplaning.
Stud fixation
At the base of each element, a special retaining "anchor" is formed. During vulcanization, the compound envelops the anchor on all sides, creating a mechanical lock. This design resists tearing loads that occur when braking on ice. The studs remain in place even after several seasons of active operation.
Elasticity at extreme temperatures
The model uses a winter-resistant tire "cocktail" with two key components:
- increased silica content — it is responsible for micro-adhesion to the icy surface at the molecular level;
- high-efficiency additives — they maintain the mobility of polymer chains even at very low temperatures.
The rubber does not become "stiff", remaining elastic. This directly affects the contact patch — a soft tire better adapts to the unevenness of ice and snow, providing a tighter grip.
Key features of Unistar Ice Protection S:
- winter model for a wide range of passenger cars;
- directed tread with a V-shaped drainage groove scheme and open shoulder areas;
- applicability — city and highways, operation is allowed outside the city on flat roads without asphalt coating;
- resistance to aquaplaning and slushplaning due to the directed drainage system;
- increased strength of stud fixation, ensuring the preservation of the full range of operating characteristics for several seasons;
- frost-resistant compound with increased silica content and special additives.
