Pirelli Winter Sottozero Serie II Ultra High Performance Winter Tire

The Pirelli Winter Sottozero Serie II is Pirelli's second-generation ultra-high performance winter tire, purpose-engineered for drivers of premium sports cars and high-powered performance vehicles who demand confident cold-weather capability without sacrificing dynamic driving character. Backed by a record number of OE homologations, the Winter Sottozero Serie II is the preferred factory-fit winter tire of leading premium automakers worldwide — designed to perform across the full spectrum of unpredictable winter road conditions, not just deep snow.

Key Technologies:

• Asymmetrical Tread Pattern: Two distinct tread zones work in concert — the inner zone efficiently evacuates water and slush from the contact patch, while the outer zone's rigid, widely-spaced blocks deliver enhanced cornering grip and confident snow traction
• Interactive Brickwall Siping (I.B.S.): Pirelli's patented sipe construction forms a brickwork pattern across the tread surface, increasing both lateral and longitudinal stability while multiplying biting edges to shorten braking distances on snow- and ice-covered roads
• Temperature Dynamic Compound: A specially formulated rubber compound optimized for wet and icy surfaces that remains pliable in temperatures below 7°C (45°F), maintaining grip and road contact where conventional all-season tires harden and lose effectiveness
• Twin-Compound Technology: Pirelli's exclusive patented dual-compound construction enhances tread performance characteristics across both the inner and outer tread zones for well-balanced winter capability
• Hydro Static Tank (HST) Grooves: Wide circumferential grooves combined with Pirelli's patented HST technology actively expel water from beneath the contact patch, delivering strong resistance to aquaplaning in wet and slushy conditions
• Twin Steel Belt Construction: Dual steel belts reinforced with a spirally wrapped polyamide cord enhance thermal stability, maintain optimal tire shape at speed, and improve durability, ride comfort, and road-following precision
• Variable Pitch Tread Design: Sequenced tread block arrangement minimizes pattern noise for a quieter, more refined driving experience
• Aromatic Oil-Free Compound: Tread compound formulated with new polymers and mixing processes for a more environmentally responsible construction

Performance Benefits:

• Strong traction and short braking distances on snow-packed, slushy, wet, and cold-dry road surfaces
• Maintains ultra-high-speed stability and precise steering response in cold-weather conditions
• Optimized contact patch geometry delivers responsive, predictable handling across varied winter surfaces
• Reduced road vibration and cabin noise compared to conventional winter tire designs
• Three-Peak Mountain Snowflake (3PMSF) certified — meets the industry's severe snow service requirements
• Run Flat variants available, allowing continued mobility following a loss of tire pressure
• Record number of OE homologations — the factory winter fitment choice of leading premium and performance automakers

Rooted in Pirelli's motorsport heritage and precision tire engineering, the Winter Sottozero Serie II is the performance driver's winter tire — delivering the traction, control, and safety demanded by cold and winter conditions without compromise. Available in both standard and Run Flat constructions across a broad range of fitments for high-performance passenger cars and sports sedans. Pirelli recommends installing Winter Sottozero Serie II tires in complete sets of four for optimal handling balance and performance.
