Pirelli has revealed the Scorpion All Season SF3, an all-season tire designed specifically for SUVs, expanding the technical features of the Cinturato All Season SF3.
Pirelli prioritized safety and versatility in different weather conditions, which has been confirmed by independent Dekra tests, in which the tire achieved excellent results in cumulative braking. It also features an A rating on the European label for wet grip. The tire’s snow performance is certified by the 3PMSF marking and the tire is rated B for external noise on the EU label and ranked in classes A and B for rolling resistance.
Optimized for SUV dynamics
To support the handling and weight of SUVs, specific adaptations and technological solutions were introduced to the tire. These include reinforced tread blocks with larger dimensions and a progressive entry geometry that gradually increases the contact patch between the tread block and the road. This is designed to avoid sudden pressure peaks and enables a smoother interaction with the asphalt, reducing vibrations and road noise. The tire is also designed to improve driving comfort, stability and grip, especially in heavier vehicles.
Adaptive tread structure
The tire features a special tread pattern with an adaptive structure, inherited from the Cinturato All Season SF3. It includes 3D sipes that change shape from straight lines to a zigzag pattern as the tires wear down, increasing the surface area capable of gripping snow even as tread depth decreases. The adaptive design also affects the movement of the sipes. With their ability to close and compact under high contact stress, the tread transforms from a winter-like siped pattern to a more summer-like profile. This enables effective performance on dry surfaces and during braking.
Material innovation
The adaptive behavior of the tread is made possible by material innovation. To balance these wider grooves, the Scorpion All Season SF3 compound is formulated for stiffness, stability and response at high temperatures. Winter grip is enhanced through the introduction of innovative materials, including a new mix of polymers with specific microstructures that ensure high mobility at low temperatures. New natural-origin resins improve grip on cold surfaces, while liquid polymers enhance snow performance without compromising wet traction.
Pirelli used its AI-based Virtual Compounder tool, which assisted engineers in selecting the best material mix and 3D modelling also played a crucial role, enabling parallel design of the compound and tread pattern.
Available range
Available in sizes from 17in to 21in, the tire is distinguished by the Elect marking, denoting models equipped with technology solutions tailored for BEVs and PHEVs. It is also offered with the Pirelli Noise Cancelling System (PNCS), which reduces tire rolling noise thanks to a special sound-absorbing material inside the tire.
In related news, Apollo Tyres has launched its latest ultra-high performance (UHP) tire, the Aspire 5. The tire has been designed to address the growth of the Indian luxury car segment and is available in sizes from 17in-20in. Read the full story here
