Pirelli SOTTOZERO Serie II

Winter SOTTOZERO™ Serie II is designed to provide drivers with the versatility and safety needed to navigate in harsh fall and winter weather driving conditions. It represents a versatile and safe solution for drivers who encounter fall and winter weather conditions, be they dry, wet or snowy. Pirelli’s SOTTOZERO™ Serie II actively reacts in the presence of wet asphalt and low external temperatures (under 45°F), greatly reducing the possibility of aquaplaning and guarantees the best performance on all surfaces.

 

The innovative asymmetric tread design of the Sottozero Serie II and its openly sporty character can be sub-divided into two distinct areas comprised of differentiated compositions due to the exclusive and patented bi-composition (present on W270). The internal module of the tire adopts a rigid composition that reacts to a more humid climate and helps manages the stability and control of the vehicle at high speeds on wet and dry surfaces, giving the Sottozero Serie II serious advantages in traction.

The internal module is characterized by:

• Wide molded grooves, in order to effectively expel the water.
  
• Special water containment basins (HST - Hydro Static Tank). Patented by Pirelli, HST guarantees a better containment of water in the grooves that reduces the phenomenon of aquaplaning.
  

The external module characterized by more rigid wedges and greater distanced privileges the winter performance on snow due to the support of a softer compound optimised for this purpose with the method TDC - Temperature Dynamic Compound (also on W210/W240).

The external module is characterized by rigid wedges allowing for more confidence inspiring winter performance on snow with Pirelli's TDC - Temperature Dynamic Compound, a softer compound that was created specifically for snow duty (also on W210/W240).

The primary characteristics of those sections are:

• A double band of wedges that guarantees stability and adherence during acceleration and braking in any condition.
  
• Three-deep longitudinal canals that improve the fluid dynamics of the design - thus reducing the occurrence of aquaplaning.
  
• A thick lamination "like brickwork" (IBS - Interactive Brickwork Siping), that remarkably improves the traction capacity of the snow and the grip of dry surfaces.
