Falken 28036572-NDFP Azenis FK510 255/40ZR20 XL 101Y Ultra High Performance Summer Tire

The Falken Azenis FK510 255/40ZR20 XL 101(Y) is an ultra-high performance summer tire engineered for drivers of premium and luxury sport vehicles who demand exceptional grip and outstanding handling in both dry and wet conditions. Built on Falken's latest generation platform, the FK510 combines cutting-edge compound technology with an advanced asymmetric tread design to deliver confidence-inspiring performance at speed.

Key Features:

• 4D Nano Design Tread Compound – Optimizes high-performance polymer compounds at the molecular level, enhancing both wet weather traction and long-term tread wear resistance
• Hybrid Undertread Cap Ply – Uses aramid and nylon materials to increase rigidity and high-speed stability for the tire's XL (Extra Load) construction
• Tension Control Technology – Proprietary casing mold shape creates a flexible middle sidewall that absorbs road shock while the rigid outer shoulder tread delivers precise handling and enhanced steering response
• Adaptive Constant Pressure (ACP) Pattern Design – Distributes driving forces evenly across the tread surface to improve contact patch consistency, stopping distances, and cornering stability
• Switchback Siping with Variable Sipe Depth – Enhances both dry and wet traction while preserving overall block rigidity
• Four Circumferential Grooves – Wide channels efficiently evacuate water from beneath the contact patch to resist hydroplaning
• Wide Shoulder Blocks – Increase biting edges during cornering and maneuvering for enhanced lateral grip
• Asymmetric Tread Design – Optimizes contact surface geometry during cornering to improve wet-weather grip and high-speed stability
• Road Hazard Protection Warranty – Covers unrepairable damage for the first 3/32nds of tread life or 2 years from purchase, whichever comes first
• 30-Day Ride Guarantee – Try the tire risk-free for 30 days or 1,000 miles
