Michelin 23140 Pilot Sport Cup 2 R 305/30ZR21 107Y XL Summer Performance Tire

The Michelin Pilot Sport Cup 2 R (23140) is a street-legal track and competition tire engineered for drivers of high-output supercars and sports cars who demand maximum performance and faster lap times. Built around a tread compound derived directly from Michelin's motorsport program, this ultra-high performance summer tire delivers exceptional dry grip and precise handling in a DOT-compliant package sized at 305/30ZR21 107(Y) XL.

Key Features:

• Motorsport-Derived Tread Compound: The high-traction compound is taken directly from Michelin's racing tires, engineered for maximum grip under acceleration, braking, and hard cornering.
• Bi-Compound Technology: Two distinct rubber compounds are used across the tread width — a softer outboard compound for maximum dry adhesion in curves and a more rigid inboard elastomer for precise steering response and wet grip.
• Asymmetric Tread Pattern with Reduced Void Area: The updated asymmetric design minimizes void area to keep more rubber in contact with the road surface, improving dry traction and stability.
• Variable Contact Patch Technology: Optimizes the tire's footprint pressure distribution, keeping more rubber in contact during cornering for superior grip through tight turns.
• Race-Inspired Reinforced Shoulder Construction: The massive outboard shoulder features fewer lateral notches and narrower circumferential grooves, creating wider tread ribs and a larger dry-contact patch.
• Wet-Focused Inner Shoulder: Deep lateral notches on the inner shoulder actively evacuate water from the footprint to aid wet-weather traction.
• Extra Load (XL) Rating: Reinforced construction supports higher load capacities and inflation pressures for demanding performance applications.
• 20% Deeper Tread Depth vs. Competition: Provides greater track longevity compared to rival ultra-high performance tires.
• DOT Compliant: Street-legal for road use while delivering genuine track-day capability.

Important Note: While the Pilot Sport Cup 2 R meets DOT requirements for road use, it is a summer-only tire and is not recommended for use in wet conditions involving standing water due to the risk of hydroplaning. It is not suitable for use in cold, near-freezing, or winter conditions. This is a single tire — one tire per purchase.
