  
 The Pilot Sport A/S Plus is the Ultra High Performance All-Season tire member of Michelin's Pilot family of low profile, high-speed tires that represents the evolution of the Pilot Sport A/S. Developed for the drivers of high-end sports cars, sporty coupes and performance sedans, the Pilot Sport A/S Plus is designed to combine enhanced all-weather performance, wet grip and treadwear along with year-round traction, including in light snow. The Pilot Sport A/S Plus features Michelin's TriFusion Compound that molds three different tread compounds side-by-side using the precise capabilities of Michelin's "C3M" tire manufacturing process. The tread compound in both shoulders improves dry handling, the compound used between the shoulders and center rib enhances wet, snow and cold weather traction while the compound used in the center rib boosts wet traction. These three compounds are molded into a directional tread design (shared with Pilot Sport A/S tires) that features a continuous circumferential center rib (to provide communicative road feel and reduce noise on dry roads), high angle directional tread blocks (to sharpen steering response and dry road handling) along with circumferential and high angle lateral grooves (to resist hydroplaning and enhance wet traction). The tire's internal structure includes two high-tensile, lightweight steel cord belts under the tread area reinforced with Michelin's "Filament At Zero" (FAZ) technology that spirally wraps an individual strand of polyamide across the entire tread (similar to the way fishing line is wound onto a fishing reel) to increase treadwear and ride comfort while providing high speed durability and predictable handling. NOTE: Pilot Sport A/S Plus tires can be mixed with earlier Pilot Sport A/S tires in axle pairs as long as the Pilot Sport A/S Plus tires are installed on the rear axle.
