The Scorpion Zero All Season Plus is Pirelli's Street/Sport Truck All-Season tire developed for the drivers of powerful crossovers and SUVs, as well as sport-tuned and performance pickup trucks looking for a combination of high performance capability with all-season utility, including the ability to drive in light snow.The Scorpion Zero All Season Plus utilizes Pirelli's newest high-performance, all-season tread compound molded into an asymmetric tread design. The high-silica content matrix also features special polymer blends and resins designed for balanced, all-around performance. The asymmetric pattern utilizes large outboard shoulder blocks for responsive handling and braking traction in dry and wet conditions, and the rigid central blocks further aid dry grip. The addition of special silica improves wet-weather traction, while four wide, circumferential grooves evacuate water from the contact patch to resist hydroplaning. Smaller, inboard tread blocks feature winter-focused zigzag sipes to create the biting edges needed for traction in slippery winter conditions.Internal construction of the Scorpion Zero All Season Plus includes two wide steel belts with a spirally wound, nylon reinforcement. The ability to vary the tension of the reinforcement allows Pirelli''s engineers to tune the balance between stiffness and handling, and the two-ply polyester casing further improves ride comfort.
