Technologies used in Viatti winter tyres

The optimally constructed profile and the distribution of materials in the sidewall area ensure a balance of handling and damping characteristics of the tire for comfortable operation in all conditions.

The central part of the tread pattern with diamond-shaped blocks provides directional stability when driving in a straight line and cornering control. The blocks have additional broken side surfaces to create edges of adhesion to the road surface in winter operation.

Transverse grooves with direct outlet provide traction characteristics during acceleration and braking properties on icy and snowy surfaces. Due to the optimal wall inclination, volume and straightness, the grooves have a high degree of self-cleaning from snow and dirt.

The reinforcement of the tread pattern blocks in the central and shoulder areas due to connecting bridges ensures a high level of stability and controllability during straight-line movement and high-speed maneuvering.

The shoulder blocks of the tread pattern, alternating in size, have a complex shape with access to the sidewall area for additional traction in deep snow conditions and a sufficient area to accommodate lateral loads during active maneuvering of the vehicle.

The area of the pattern elements creates an optimally saturated tire contact spot with the road surface, which ensures reliable and safe tire operation in various weather conditions.

The undulating shape of the lamellae increases the contact length and allows the tread pattern blocks to work just as effectively on asphalt in various driving modes.

The patented solution of the internal 3D profile of the slats creates additional rigidity of the tread pattern blocks and provides excellent handling during high-speed maneuvering.

New anti-skid spikes with a steel body to reduce wear and a tungsten carbide core with a high degree of puncture of the ice surface. The body shape allows the spike to work effectively in all directions and has a high degree of retention during operation. The efficiency of the new spike is 25% higher in terms of performance on an icy surface (relative to the Viatti Bosco Nordico range)*.

Up to 34 tracks and an 80% increased number of anti-skid spikes (compared to the Viatti Bosco Nordico) create effective grip at the point of tire contact with icy and snow-covered road surfaces during dynamic acceleration or braking, ensuring safe and comfortable operation.

The pattern elements around the anti-skid spikes create a brush effect, clearing the surface of ice or rolled snow to increase the efficiency of the spikes in acceleration and deceleration mode.

The patented solution of the step-by-step wear level indicator allows you to control the degree and uniformity of wear on the tread of the outer and inner sides and along the circumference of the tire as a whole. The 4 mm level is also an indicator of the end of operation in winter.
