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.

  1. A great tire on my ’06 Audi A3 is just mediocre on my ’05 Porsche Boxster S. I’m sure those who buy a Porsche as a luxury car will be more than happy. Those who want performance will be disappointed. The tire can get a bit squirrelly in hard cornering though it does give plenty of warning. They occasionally feel like the PSM is working very hard to keep the car glued down. They definitely do no inspire the kind of stick and confidence of a PS2 or Cup.

  2. the tires have 20,000 miles and still have plenty of treadfor this car snow traction is better than expectedin wet it really holds the road well and does not hydroplanein dry, it is not a summer tire but it does very very well on the cornersand responds very well
