The Pilot Sport Cup 2 R is Michelin's Streetable Track & Competition tire developed for the drivers of supercars and sports cars who want to maximize their vehicle's performance and reduce lap times. The Pilot Sport Cup 2 R is highly-tuned to enhance the capability of the specific vehicles it was homologated for, so it may only be sold for use in those applications. Since it is designed to help drivers realize their car's full potential in dry conditions, the Pilot Sport Cup 2 R, like all Streetable Track & Competition tires, is not intended to be used, stored, moved nor shipped in near- or below-freezing temperatures.The Pilot Sport Cup 2 R utilizes a tread compound taken directly from Michelin's motorsport tires for enhanced grip during acceleration, braking and cornering. This high-traction compound is molded into an updated, asymmetric pattern with reduced void area to improve grip in dry conditions. The massive, outboard shoulder features fewer lateral notches, and the tire's circumferential grooves are narrower, creating wider tread ribs for more rubber in the contact patch. The inner shoulder is focused on wet traction, with deep, lateral notches to evacuate water from the footprint. Even so, while Pilot Sport Cup 2 R tires meet DOT requirements, they are not recommended for driving in wet conditions where standing water is present and there is the risk of hydroplaning; drivers should drive cautiously at reduced speeds if they encounter these conditions. This is especially true of shaved or worn tires.Internal construction of the Pilot Sport Cup 2 R has been reengineered to fully exploit the additional grip provided by the updated compound and is tuned to best complement its intended vehicle application. Increased structural rigidity provides the stable base needed to withstand the forces transmitted through the tire.Note: Michelin Pilot Sport Cup 2 R tires should be stored at temperatures above 32°F (0°C). Below 14°F (-10°C) the tires should not be used, stored, moved or shipped. Lower temperatures can cause the rubber to crack. Cold compound cracking occurs as a result of improper use or storage, and therefore Michelin's warranty will not cover tires exhibiting this condition. Any tires exhibiting compound cracking must be replaced.Note: For best handling on the track or the road, Michelin advises a complete set of four Pilot Sport Cup 2 R tires should be fitted.
