The Michelin Pilot Sport A/S Plus is the next generation of all-season performance. The new Michelin Pilot Sport A/S Plus tires provide an unrivaled combination of all-weather performance and tread life. This technology is unique for high-end performance vehicles. They are the only UHP tires in the Michelin lineup to offer TriFusion™ Compound - three different compounds bonded together on the tread face for superior all-weather performance. A state-of-the-art directional tread pattern and a wet-weather silica compound have been combined for extreme wet-weather control. In addition to these superior feats of performance, the Michelin Pilot Sport A/S Plus tires are the first to make use of the enhanced MaxTouch Construction. A tire design innovation that delivers dramatically improved tread life without sacrificing performance. The Michelin Pilot Sport A/S Plus tires are backed by a 45,000-mile limited warranty.
