Engineers at Sunfull have created the SF-989 tire to provide you with complete control in harsh winter conditions. This is not just a tire, but an intelligent traction system, where every element of the tread works for your safety. The model is based on a directed symmetric tread design, specially developed for the effective removal of snow slush, water, and slush. This provides excellent stability at high speeds and minimizes the risk of hydroplaning.
The unique construction of lamellas and grooves creates a "snow capture" effect. The tire literally grips loose snow, providing traction comparable to off-road, without losing comfort and handling. Asymmetric blocks of variable geometry - large central blocks of irregular shape, separated by wide drainage channels, form an aggressive traction patch. This solution radically improves acceleration and reduces braking distance on rolled snow and ice. The numerous lamellas have a special three-dimensional structure. When loaded (braking, acceleration), they "close", increasing the stiffness of the block and the contact area. On slippery surfaces, the lamellas remain flexible, providing a multitude of microscopic hooks.
The wide shoulder and massive side blocks form an enlarged contact patch. This stabilizes the vehicle in turns, preventing skidding and loss of control, and provides exceptional traction on deep or loose snow. The special arrangement of blocks and studs, as well as the use of a modern soft winter compound that adapts to low temperatures, guarantees acoustic comfort and vibration suppression.
Key features of Sunfull SF-989:
- a special block configuration provides maximum traction on snow, which directly affects the dynamics of acceleration and reduction of braking distance;
- a dense network of three-dimensional lamellas creates a multitude of sharp edges for "biting" into ice and compacted snow, significantly increasing directional stability and preventing skidding;
- elongated shoulder blocks and an extended contact patch provide instant response to steering wheel rotation and confident passage of turns;
- a rational arrangement of tread elements in combination with a special soft rubber compound reduces rolling noise and dampens road vibrations.
