The Pilot Sport A/S Plus N-Spec is Michelin's High Performance All-Season tire developed in conjunction with Porsche for Panamera, Panamera 4, Panamera S, Panamera 4S, and even Panamera Turbo models as an optional all-season tire offering. Pilot Sport A/S Plus N-Spec tires are designed to combine comfort, handling and all-season traction, even in light snow. The Pilot Sport A/S Plus N-Spec features an all-season tread compound molded into a symmetric pattern that helps balance dry, wet and wintertime traction. Stable shoulder blocks and a continuous center rib boost responsiveness and highway stability, while wide circumferential grooves help resist hydroplaning and 2-D Active Sipes improve handling in rain and snow. The tire's internal structure features twin steel belts reinforced with Michelin's FAZ Technology (Filament At Zero degrees) that winds polyester and aramid/nylon cords spirally under the tread area to provide a stable feel and crisp steering, while polyester cord reinforced sidewalls enhance ride quality. WARNING: Pilot Sport A/S Plus N-Spec tires feature a unique tread design that cannot be mixed with conventional Pilot Sport A/S Plus tires. NOTE: While High Performance All-Season tires offer all-season versatility including traction in light snow, tire sizes featuring extremely wide tread widths may limit the traction this type of tire can provide in deep snow.
