The Pilot Sport A/S 3 N-Spec is Michelin's High Performance All-Season tire developed in conjunction with Porsche for Panamera 4S, Panamera 4 E-Hybrid and Panamera Turbo models as an optional all-season tire offering. Pilot Sport A/S 3 N-Spec tires are designed to combine noise and ride comfort, handling and all-season traction, even in light snow. The Pilot Sport A/S 3 N-Spec features an all-season tread compound molded into an asymmetric pattern to deliver balanced dry, wet and wintertime traction. The independent tread blocks of the circumferential ribs are interlocked for stability and confident handling, with lateral notches and continuous grooves to evacuate water from the footprint and reduce the risk of hydroplaning. Multiple sipes and block edges work to create traction on slippery surfaces to provide grip in wintry conditions. The tire's internal structure features two high-tensile, lightweight steel cord belts reinforced with spirally wrapped polyamide cord to combine predictable handling and high-speed durability with treadwear and ride comfort. WARNING: Pilot Sport A/S 3 N-Spec tires feature a unique tread design that cannot be mixed with conventional Pilot Sport A/S 3 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.
